Ultrasound of mammary glands with implants in Moscow

Ultrasound of the mammary glands with implants is the main non-invasive method used to diagnose common pathologies of the mammary gland. An ultrasound should be done immediately before plastic surgery, and then repeated annually after it. The technique allows you to observe the structures of the organ after surgery, as well as timely diagnose various complications, inflammation, and neoplasms.

Also, during a diagnostic study, the diagnostician assesses the condition of the implant, determines its position and integrity. At the Hemostasis International Clinic, ultrasound examination of mammary glands with implants is carried out using modern, highly sensitive equipment that can detect any, even minor, pathological change, which is very important for early diagnosis and timely therapy.

Features of the procedure

Examination of the mammary glands after mammoplasty is carried out for two purposes:

Assess breast tissue and the condition of regional lymph nodes.
Check the condition of the implants and the body’s reaction to them.

Ultrasound examination after implantation is recommended annually. This is a safe, reliable, painless diagnostic method that allows you to monitor the condition of the organ and detect any pathological changes in the initial stages of development.

No special preparation is required for the procedure. The study is carried out from 6 to 12 days of the menstrual cycle. Ultrasound examination after mammoplasty can be planned or emergency. A routine examination is recommended to be performed a week, a month, six months after surgery. Then you need to visit a mammologist and have an ultrasound scan every year. If cysts, fibromas, or focal neoplasms are identified during diagnosis, re-diagnosis is prescribed after 6 months. An emergency ultrasound of the mammary glands with implants is performed when the patient’s well-being deteriorates, damage to the prosthesis is suspected, or the formation of tumors of various etiologies.

Ultrasound examination after mammoplasty has its own characteristics. When examining breast glands with prostheses, it is necessary to take into account that implants are installed in the lower segments, so the gland tissues are shifted upward and flattened. In addition, it is important to find out where the prosthesis is installed - under the gland or under the muscle.

Ultrasound in the first days after implantation evaluates the presence or absence of fluid around the prosthesis, which helps to exclude gray matter and hematoma, and if they are detected, promptly prescribe treatment. It is also important to evaluate the shape, outline, and integrity of the implant shell.

In the later stages after mammoplasty, ultrasound is used to assess the condition of the prosthesis itself, its shape, contours, mobility, and the presence of pericapsular fibrous changes. Particular attention is paid to neoplasms in the mammary glands, because any tumor can degenerate into malignant in the future. The condition of regional lymph nodes is carefully studied. The conclusion is made on the basis of ultrasound examination, examination, palpation, and laboratory diagnostics. If an ultrasound reveals a tumor with signs of malignancy, an additional MRI of the breast is prescribed.

Introduction

The problem of breast enlargement has worried women since ancient times. According to statistics, the number of people wishing to restore lost tissue volume or compensate for natural deficiencies with the help of plastic surgery increases annually by 10% [1].

The history of surgical breast augmentation goes back more than 100 years. The introduction of liquid paraffin, wax, and vegetable oils into the mammary gland was accompanied by suppuration, the appearance of compactions, rejection of foreign material, the formation of fistulas and granulomas. Foreign materials caused embolism of blood vessels and accumulated in the organs of the reticuloendothelial system. They tried to make prostheses from glass, metal, and ivory, but they also often shifted and were rejected.

In 1895, surgeon Vincenzo Cerni was the first to replace a defect with a lipoma removed from the same patient after excision of part of the mammary gland.

Since the 40s of the last century, silicone has been used as an injection material. The first women to be injected with liquid silicone to enlarge their mammary glands were Japanese prostitutes, since after World War II the American military contingent on the Japanese islands had a demand for women with full breasts. The consequences were the same: fibrosis, necrosis of soft tissues, infection, fistulas, granulomas, migration of the substance into the surrounding tissues with subsequent sclerosis.

In the early 60s, prosthetics were created from polyvinyl alcohol in the form of a sponge. The results became better, but rough connective tissue also formed around the sponge, which deformed the prosthesis; it became unnaturally round, hard and decreased in volume.

At the same time, the first silicone shell endoprostheses filled with gel or saline were implanted.

In the 90s, injection plastic surgery was again attempted with new polyacrylamide hydrogel water-swelling materials similar to human adipose tissue. But the same complications began to arise again and the toxicity of the gel was proven. Injection plastic surgery continues to occupy the minds of surgeons, and 100 years after Cherny’s experience, the technique of lipotransfer or lipofilling appears: an increase of 1–1.5 sizes by introducing into each breast about 300 ml of own fat obtained by liposuction, that is, by washing out with a special solution under low pressure.

Modern shell endoprostheses have a dense capsule of 2–3–4 or even 5 layers of seamless silicone elastic rubber, filled with gel, or less often, saline filler [1]. The shape can be spherical or teardrop-shaped, the surface smooth or textured. The prosthesis can be placed under the glandular-fibrous complex or under the pectoralis major muscle. But even when installing shell endoprostheses, seromas, hematomas, capsular fibrosis and capsular contracture, implant ruptures, gel migration, inflammation, and liponecrosis can occur. 92% of complications occur in the late postoperative period – over 2 months.

Currently, ultrasound examination (US) is one of the main methods for diagnosing diseases of the mammary glands; the information content of the study increases with increasing scanning frequency (5.0–7.5–10.0 MHz) and the size of the working surface of the sensor 40–60 mm. Thus, for radial ductal echography, a sensor with a frequency of up to 13 MHz and a length of 92 mm is used [2].

The most modern technique that allows you to obtain the most complete image of the mammary gland is automatic volumetric scanning, or ultrasound tomosynthesis, sonotomography [3] using a special attachment that provides automatic movement of a high-frequency sensor (15 MHz) 15.4 cm wide, which registers in one pass 318 slices 0.5 mm thick. The maximum volume of tissue for research is 1552.3 cm3 [4]. The obtained data is analyzed on a workstation, saving the entire data array provides the possibility of post-processing, and standard installations ensure high reproducibility of the technique.

Types of breast structure

ASR 1 (type A) – predominance of adipose tissue.
ASR 2 (type B) – the glandular-fibrous complex occupies less than 50%.
ASR 3 (type C) – glandular-fibrous complex occupies more than 50%.
ASR 4 (type D) – the mammary gland consists 100% of the glandular-fibrous complex, “dense background”.

Normally, the reconstructed coronal section (Fig. 1a) reflects the radial structure of the mammary gland, resembling images obtained with tomosynthesis (Fig. 1b).

Today, in his practical work, an ultrasound diagnostic doctor may encounter the consequences not only of injection or sheath mammoplasty, performed for purely cosmetic purposes, but also with the results of restoring the shape and volume of the mammary gland after surgical treatment of a tumor, including in combination with radiation therapy. As illustrations, we present the following clinical observations in which automatic ultrasound scanning of the mammary glands was performed on a modern ultrasound device with an ABVS (automatic breast volume scanning) attachment.

Clinical observation 1

Patient A., 45 years old, complained of painful lumps in both mammary glands. From the anamnesis it is known that 15 years ago injection mammoplasty was performed - the introduction of gel into both mammary glands in order to increase volume. With automatic volumetric scanning (Fig. 2a, 2b), as well as with tomosynthesis (Fig. 2c, 2d), the gel is detected in the form of scar-gel conglomerates with clear contours; encapsulated masses and diffuse impregnation of tissues. Over 4 years of observation, the ultrasound picture did not change. Conclusion: polyacrylamide mammary syndrome.

Obviously, the presence of gel in breast tissue makes it difficult to diagnose other diseases; in this situation, a multiparametric approach and dynamic observation are certainly necessary [5].

It is believed that after injection of your own fat, taken from the abdominal area, up to 75% of it remains viable and is included in the metabolism, the rest of the fat is absorbed.

Clinical observation 2

Patient P., 36 years old. He makes no complaints. From the anamnesis it is known that 2.5 years ago, lipotransfer was performed to correct the volume of the mammary glands. During mammography, diffusely scattered amorphous calcifications of various sizes with a tendency to grouping are noted in the mammary glands. With automatic volumetric scanning (Fig. 3a, 3b), multiple areas of increased echogenicity with liquid inclusions with partially calcified walls are visualized in the subcutaneous fat tissue - cysts formed in areas of liponecrosis. With tomosynthesis (Fig. 3c, 3d), these areas are visualized as multiple intradermal calcifications.

Patient V., 70 years old. Observed for 18 years after radical resection of the left breast for stage I cancer with simultaneous plastic surgery of the latissimus dorsi muscle. With automatic volumetric scanning of the left breast in the medial projection in a coronal section at the skin level, as in a regular photograph, the area of the postoperative scar is clearly visible, stretching from the lower internal through the upper internal and entire upper external quadrant, the mammary gland is deformed, the nipple is preserved (Fig. 4a). At a depth of 19.5 mm (Fig. 4b), the postoperative scar is still visible, below the nipple, marked with a yellow marker, there is a shadow of calcification, which has an uneven but smooth contour, and at the border of the outer quadrants there is a large hypoechoic area with an uneven contour without a symptom radiance, in the cine-loop mode it is clear that this is a muscle flap that stretches from the back.

Clinical observation 4

Patient M., 73 years old, complains of periodic discomfort in the right mammary gland. From the anamnesis it is known that in May 2014 she underwent a radical resection of the right breast with simultaneous nipple plastic surgery for stage I cancer (histologically - infiltrative ductal carcinoma 1.0 x 0.8 cm, RE-8; RP-0; HER- 2; neu–0; Ki 67–25%) followed by external beam radiation therapy at 50 Gy. Hormone therapy with tamoxifen 20 mg daily has been carried out since September 2014. Since the patient has macromastia, the volume of removed tissue was not replenished. Upon examination in June 2014, the right mammary gland was deformed due to surgery, swollen, hyperpigmentation was observed on the skin of the radiation fields, and diffuse thickening of soft tissues was observed in the area of the scar.

With automatic volumetric scanning (Fig. 5), there is a thickening and diffuse increase in the echogenicity of the skin, the picture of the surface section resembles a lemon peel (Fig. 5a), the echogenicity of subcutaneous fat is increased (Fig. 5b), and the lymphatic vessels are significantly dilated (Fig. 5c) .

The ultrasound picture of an unchanged shell implant during automatic volumetric scanning (Fig. 7) is characterized by smooth contours, a continuous capsule and homogeneous contents. A fold depth of up to 4 mm is considered acceptable. The thickness of the periprosthetic fibrous capsule should not exceed 1.5 mm.

Clinical observation 5

Patient P., 50 years old, came in 4 years after endoprosthetics with complaints of periodic discomfort in the left mammary gland. With automatic volumetric scanning, the unevenness of the anterior surface of the right breast implant is clearly visible (Fig. 8a), and it is easy to assess the number and extent of folds. In the left mammary gland (Fig. 8b), the glandular-fibrous complex is shifted to the upper outer quadrant, where several small cysts are visualized.

The image of textured implants differs from smooth capsule implants in the granularity of the structure of their own capsules (Fig. 9a, b). With the same depth of folds (4 mm each), the contents may be different: in Fig. 9a, in the contents of the fold, small hyperechoic inclusions without shadows are clearly differentiated, which is a sign of inflammation, in Fig. 9b the contents are homogeneous. There is one more difference: in Fig. 9a, the periprosthetic fibrous capsule is stretched over the fold like a bowstring [3], while in Fig. 9b, the fibrous capsule is of uneven thickness, but sags above the fold, that is, it has not yet wrinkled. Thus, in Fig. 9a – initial phenomena of capsular contracture; in Fig. 9b – capsular fibrosis.

Patient K., 41 years old, came in 12 years after breast surgery with complaints of deformation of the left mammary gland. On mammograms of the left breast, a retromammary shadow of the implant with clear and even contours, diffuse fibrocystic mastopathy predominantly with a glandular component and signs of adenosis, and well-defined glandular tissue are determined. Against this background, it is not possible to judge the presence of nodular formations (dense background). With automatic volumetric scanning in the left mammary gland, a smooth-capsular two-layer implant with a pronounced deformation along the anterior surface due to a bizarre pattern of folds, a hypoechoic area is visualized above the nipple (Fig. 10a), in the sagittal projection (Fig. 10b) the rupture zone of the implant’s own capsule is clearly visible and fibrous capsule with the formation of a gel depot in the breast tissue – external rupture of the implant.

Patient X., 42 years old, complained of asymmetry of the mammary glands. From the anamnesis it is known that endoprosthetics was performed in 2007 for cosmetic purposes, in 2020 a pregnancy occurred that ended in childbirth, the child was breastfed for up to 1.5 years. By the time of the study, lactation was completely completed. With automatic volumetric scanning depth at skin level (Fig. 11), it is possible to judge the appearance of the mammary glands with photographic accuracy.

Conclusion

The presented observations demonstrate the possibilities of automatic volumetric scanning of the mammary glands after various types of mammoplasty, both for purely cosmetic purposes and to replenish the volume of removed tissue after surgical treatment of tumor formations. The advantages of automatic volumetric scanning over X-ray techniques are the absence of radiation exposure and the risk of rupture of the endoprosthesis due to its mechanical compression under conditions of gland fixation; over conventional ultrasound - a higher scanning frequency and, therefore, higher resolution, a full-format image of the entire gland, ease of assessment of the number and length of defects, precise topography of the “find”, high reproducibility; overcoming such disadvantages of ultrasound as subjectivity and operator dependence through standardization of installations and the process of collecting information, the possibility of post-processing and retrospective analysis.

How does the procedure work?

Algorithm for ultrasound diagnostics of breasts with implants:

The doctor asks the patient to undress to the waist, sit comfortably on the couch and relax.
A conductor gel is applied to the skin of the chest, which enhances the permeability of ultrasonic waves.
The ultrasound sensor is applied to the skin and moves across the entire area under study. The high-resolution image is visualized on the monitor screen. The diagnostician assesses the condition of the tissues of the organ and the implant, and immediately during the diagnosis voices the identified pathologies, so a preliminary diagnosis can be found out immediately.
In some cases, the specialist may ask you to change your body position or raise your arms.

The results of the study are recorded in an ultrasound protocol, which is given to the patient immediately after completion of the diagnosis. The conclusion must be shown to a mammologist who will study the data in detail and determine an accurate diagnosis.

Indications for ultrasound

A woman should have an ultrasound examination of the breast if she has:

Epilator Yes Finishing Touch. An excellent epilator that helps get rid of even the coarsest hair on any part of the body. Order!

Top Model Secret - Liquid tights. A unique cream with the effect of “liquid tights”. Ideally adapts to the skin tone of the legs. Order now!

frequent pain in the chest area
there is blood or milky (not during feeding) discharge
there are palpable seals
enlarged lymph nodes

In any uncomfortable situations or unpleasant sensations, it is better to consult a doctor and have an ultrasound examination of the breast to protect yourself from various pathological processes.

Indications and contraindications for diagnosis

You can sign up for an ultrasound scan of mammary glands with implants at the Hemostasis International Clinic according to your doctor’s indications or at your own request. Indications:

painful lumps detected during palpation;
pain, discomfort in the chest that does not go away for a long time;
pathological discharge from the nipples with purulent, bloody, serous inclusions
inflammation of the lymph nodes;
elevated temperature of unknown origin;
breast skin changes;
pronounced asymmetry of the glands;
planned examination of the condition of breast prostheses.

The procedure has no absolute contraindications. Diagnosis will have to be postponed for a while if there are wounds, ulcers, or rashes on the skin of the chest. Also, the procedure is not possible if the woman has a more viral infectious disease, accompanied by fever, deterioration in general health. As soon as the condition returns to normal, you can sign up for an ultrasound scan at a time convenient for you.

Breast implant location

In order for the ultrasound examination to take place without any problems, before placing the implant, you need to decide what position it will occupy. If it is located above the pectoral muscle, then 30% of the mammary gland will not be visible on ultrasound due to the shadow of the implant. If it is located under the muscle, a maximum of 10% will not be visible. Therefore, to obtain more reliable data, it is better to insert the implant under the pectoral muscle.

Breast punctures. Types, indications, cost

A puncture is a puncture of the breast tissue. A small number of tissue cells are collected from the puncture to determine the cellular composition of the tissue (cytological examination). It is carried out when nodular formations in the mammary glands are detected by ultrasound, mammography or palpation.

Palpable (determined by hand) formations are punctured without instrumental support.

Non-palpable (not detectable by hand) formations are punctured under ultrasound or x-ray control in order to most reliably take material directly from the node.

When puncturing cysts or liquid formations, liquid contents are evacuated from the cavity of the formation. This is not only a diagnostic, but also a therapeutic manipulation. Against the background of subsequent therapy, the empty cyst cavity grows together

Preoperative interstitial marking is the staining of an area of breast tissue before surgical treatment. It is carried out under the control of ultrasound or mammography for the most accurate and less traumatic surgical treatment. To do this, a special coloring marking substance is injected into the location of the tumor.

Our Center's mammologists perform all types of diagnostic and therapeutic puncture techniques. You can make an appointment with mammologists by calling: (495) 942-40-20 from 8.00 to 20.00

Myths and reality

Many people associate having an MRI with dental implants with dire consequences, but it’s time to debunk these myths.

The first common myth is that implants become dislodged during the diagnostic procedure and damage soft tissue. In fact, the force of a magnetic field can only displace those elements that are not fixed in the body. These could be surgical clips on the vessels of the brain or on the heart, shrapnel, bullets. As for the pins, they are securely fixed in the bone tissue and will not be able to move and damage the oral cavity during an MRI.
The second myth is related to the tomograph’s ability to heat metals. It was already mentioned earlier that the magnetic field actively affects only ferromagnets, that is, medical products made of steel. Depending on the dimensions of the product, they may indeed heat up during the diagnostic procedure, but you should only be wary if the dimensions of the product are large enough. Don't worry, there are no implants of this size in the oral cavity. As for other materials, they are absolutely safe and do not heat up during an MRI.

If the patient still has concerns about pain, there is no need to worry, since there is always the opportunity to use a special button that the specialist gives before starting the diagnosis.

How does the patient feel during the procedure?

Many patients with implants are worried about how they will feel during an MRI and whether there will be pain. However, there is no need to worry about this. The effect of a magnetic field on the body is determined only by the chemical composition of the alloy from which the implant is made, so this nuance must be clarified before the procedure. Otherwise, the operation of the tomograph is standard and does not cause pain or discomfort, with the exception of noise, which can be avoided using headphones.

Possible image distortion

Distortion of diagnostic results is the only unpleasant consequence of an MRI in the presence of dental implants, which is why the specialist must be warned about the presence of such implants. The presence of pins in the teeth is not a categorical contraindication; however, the results may be distorted, but this can be avoided.

On different tomograph models used by a particular clinic, a specialist can change the settings depending on the type of dental implant, which will make the images as clear as possible. To do this, the patient must take an X-ray of his jaws and bring a panoramic image, which will be performed by MRI. The photo should clearly show the dentures and their location. MRI may also be used to examine the oral cavity, but such situations are extremely rare, since traditionally this is done using conventional x-rays or computed tomography. When using a tomograph to scan other areas of the body, the results are not distorted, and the procedure proceeds in a standard manner.

As you can see, MRI with dental implants follows a standard procedure and does not cause negative consequences or pain. The only thing you need to do is to warn the specialist in advance about the presence of foreign bodies in the body and clarify what materials they are made of.

Hardware diagnostics, without which modern medicine is unthinkable, involves exposing patients to various types of radiation, including electromagnetic radiation.

The dental apparatus of a person, especially an elderly person, most likely contains metal products - crowns, inlays, implants.

How does their presence affect the results of an MRI examination? What contraindications and precautions are there for a person with implants undergoing a magnetic resonance examination? Is MRI dangerous for him? Do I need to prepare specially for it?

Information about all this is presented below.

How is it carried out?

The procedure involves a special table on which the patient lies. This table automatically slides into the cylindrical shape of a special scanner. When performing a tomography, the patient must wear headphones, as the device makes some noise. The doctor performing the examination uses radio waves to adjust the image quality and the patient should not move for 10-30 minutes so as not to distort the diagnostic results.

During the procedure, two-way audio communication is used between the patient and the doctor. If the patient does not feel well during the process, he can inform the doctor about it. Sometimes, for the accuracy of the study, the subject cannot breathe.

Types of implants with which MRI can be done

Dental prosthetics can be done using metal-ceramic crowns, pins and implants, which are a relative contraindication for MRI. Previously, steel and gold crowns were placed, but now they are made from metal alloys based on cobalt-nickel, cobalt-chrome, gold, platinum, coated with ceramics. They are attached to the remaining part of the tooth or a pin (screw) inserted into the tooth root. If a tooth is missing (adontia), an implant is implanted into the jaw.

Implants can be made from:

cobalt-chromium alloy;
Titanium and its compounds are an inert material, do not react to the field created by a magnet, take root well, and are used for the manufacture of medical implants.

What does a magnetic field do to an implant during MRI and is it possible to perform this procedure? Metals behave differently under the influence of a magnet:

paramagnetic materials practically do not react to a magnetic field. These are platinum, titanium, zirconium;
Diamagnets repel a magnetic field, their temperature does not change;
Ferromagnets are magnetized, displaced, and their temperature rises. These include iron, cobalt, nickel, chromium.

This is interesting!

A contrast agent that contains halidonium has been successfully used to visualize blood flow. If the ferromagnetic metal is not dangerous, then the paramagnetic substances from which implants are made can be used in MRI.

The severity of the reaction of the metal to the magnet depends on the mass of the object. They found that 20 cm of steel wire heats up to 47 degrees Celsius in a mid-polar tomograph. The mass of prostheses is much smaller and they consist of alloys, the structure of which changes the ferromagnetic properties. The dentures are firmly attached to the jaw bone, and under the influence of a magnet, only a loose object can move - a vascular clip, shot, shrapnel, mine fragments.

It is possible to do an MRI with a dental implant; it is not dangerous for the patient. But with an MRI implant, you can get a distorted image, which makes it unsuitable for diagnosis.

Distortions are observed in the images:

brain, head;
chest (heart, lungs, etc.);
shoulder joints.

Images of the abdominal cavity, pelvis and lower extremities do not reveal any defects. Devices have appeared that can improve image quality; you just need to change the settings. If you have an MRI with a dental implant, notify your doctor, and he will decide whether you can do an MRI or whether it should be replaced with another method.

Titanium implants provide a minimal change in the image during MRI, and you can do MRI with them. It is necessary to bring X-ray data and conduct a comparative analysis. Before an MRI, you can check with your dentist what material the dental implant is made of; this will allow the doctor to correctly set up the tomograph.

Every woman should take care of her health and know that after 35 years it is necessary to undergo breast ultrasound and fluorography once a year. And after breast augmentation, this is extremely necessary. But most girls after plastic surgery wonder whether the examination after the operation will be reliable, and whether all areas of the breast will be visible on the machines.

It is very important to take care of yourself and think about the future, so it is necessary to undergo all examinations on time. Will implants interfere with ultrasound, mammography, CT, MRI? This is the most popular question among women who have had breast enlargement. The answer is no! The presence of breast implants will not affect the examination in any way, and will not interfere with the eventual establishment of an accurate diagnosis, provided that the examination is carried out using modern technology.

Before the examination, it is recommended to carefully select a clinic. As a rule, all modern clinics are equipped with the latest models of technology. It is recommended to first clarify whether it is possible to conduct an examination of breasts with implants, and also consult with a specialist who will select the most suitable examination method.

Types of examinations:

1. Ultrasound - ultrasound examination

. An ultrasound must be done before plastic surgery, and then repeated annually after it. Today this is the most common examination method. Ultrasound allows you to study the mammary glands before surgery, as well as exclude various kinds of complications, inflammation and adverse changes already during the rehabilitation period.

2. Mammography

. Despite the fact that mammography is the most accurate method of breast examination, it still has some difficulties. In cases where the implant was installed above the pectoral muscle, during the examination it may block some areas of the breast. If the implant is installed under the muscle, the blocked area is insignificant. The disadvantage of this method is that it will not help determine whether a breast implant is ruptured or leaking. When performing mammography, each gland is compressed first horizontally, then vertically, so the patient should warn the doctor in advance about the presence of breast implants in the mammary glands.

3. MRI - magnetic resonance imaging

. The peculiarity of the method is the use of a powerful magnetic field. MRI allows you to determine implant rupture or leakage, identify tumor foci and metastases.

4. CT - computed tomography

. This type of examination is considered the most accurate for diagnosing breast cancer. Computed tomography is classified as an X-ray method for examining the breast.

5. Fluorography

. Breast implants are visible in the fluorography image. The patient should notify the doctor in advance about their presence, but they will not interfere with the examination of the lungs, because implants easily transmit x-rays.

Thus, the presence of breast implants will not interfere with any of the listed types of examinations and obtaining accurate data on the condition of the patient’s mammary glands and lungs.

Types of implants

The density of the breast to the touch is determined by the density of the implant itself. If you choose a soft one, the illusion of natural breasts will be complete. In addition, such implants will behave naturally: take different shapes depending on the type of bra, the presence of clothing, and body position.

If you choose dense ones, then such breasts will be pleasant to look at from a distance, but to the touch they will be clearly artificial and hard. And such breasts will retain the same shape in any position and in any underwear.

Size and shape

Gigantomania and unnatural breast shape, which was chosen in accordance with a stereotyped and exaggerated idea of beauty, without taking into account the characteristics of the figure and appearance in general, is what can often be seen in before and after photographs.

Size does not matter if, with an initial breast size of zero, a woman who is not particularly thin makes a choice between the second and incomplete third size.

If we are talking about the fourth or fifth size of a twig girl, then we can say with confidence that the unnaturalness will not only be noticeable, it will be striking.

As for the shape, some ladies after the age of thirty often change implants just to make the breast shape more natural for their age. The most interesting thing is that there is not a single comment on men’s forums about the presence of scars as a sign of silicone breasts.

The presence of scars only for women is an indicator of unnaturalness, and even then not for everyone. This means that if you approach the choice of breast size, shape and implant density wisely, then others will not have any suspicions about your new shape.
