Micromastia: Small Breasts & Ways to Make Them Bigger

Micromastia and Surgery for Very Small Breasts

Breasts are a crucial part of a woman’s body image, sexual attractiveness, and overall physique. Micromastia is a medical term that simply means “small breasts”. A lot of women have Micromastia and the condition can cause a loss of confidence, shyness and embarrassment in intimate situations.

Size is not the only aspect when it comes to how your breasts look. Yet, it’s highly important to many women who come to us wanting “bigger boobs”. Luckily, there are several ways to manage micromastia including traditional breast augmentation surgery and fat grafting to breasts.

What is Micromastia?

Micromastia means abnormally small breasts. Other names include; breast aplasia, breast hypoplasia, underdeveloped breasts, and hypomastia. The female breasts usually start growing at puberty and continue increasing in size and changing in shape until the age of around 18. In many women, the growth is not sufficient, and they are said to have underdeveloped breasts. If one breast is smaller than the other one, you then have hypomastia with breast asymmetry.

There’s no standard breast size, as a result it’s hard to define what breast size ‘small’. To a woman with F-cup breasts, C-cup breasts are small. To one with C-cup breasts, A-cups are small. Ultimately, if you feel that you have small boobs that don’t fit your perceived body image, then you have small boobs.

Why do I have small boobs (micromastia)?

Small breasts can simply just be a part of your normal body shape. This is determined by your genes. However, in some women, small boobs can be caused by a range of other factors:

  • Hormonal problems: The breasts are extremely sensitive to hormonal changes, especially during their development. Any medical conditions that cause hormonal imbalance (e.g. congenital adrenal hyperplasia) can affect breast growth. Usually, other symptoms are associated with these conditions like excessive hair. If your surgeon thinks that you might have a hormonal imbalance, he/she will refer you to an endocrinologist or gynaecologist.
  • Malnutrition and Eating disorders: Nutrition is very important for proper growth during adolescence, and a poor diet can hold back normal puberty and growth. Eating disorders like anorexia nervosa can contribute to this problem.
  • Genetic conditions and birth defects: Poland syndrome, Turner syndrome, congenital adrenal hyperplasia, and others are all conditions that can be associated with small breasts. People who have Poland syndrome are born without the major chest muscle (pectoralis major), and it’s usually on one side, which can cause breast hypoplasia and asymmetry.

What are the solutions for micromastia?

Thankfully, there are several ways to make your boobs bigger. Dr Rubinstein is highly experienced in fixing small breasts, and he has developed surgical methods that ensure you’ll have the firm and full breasts you always dreamed of having. Below are the different options when it comes to increasing the size of your breasts:

  • Breast augmentation surgery: Also called breast enhancement, breast implant surgery, or simply a boob job! It’s one of the most popular surgeries that we offer to women who want bigger and better-looking boobs. Your plastic surgeon will insert breast implants (silicone or saline-filled) into your breasts. Depending on your natural body shape, your skin laxity, and desired look, he/she will choose implants that will deliver the best results.
  • Fat grafting: Also called fat transfer. This method is a very popular method of enlarging and contour the breasts. During this procedure, your plastic surgeon harvests excess fat from other areas of your body (like the abdomen or buttocks) by liposuction and injects the fat carefully and strategically into your boobs to enlarge them and contour their shape. With fat transfer breast augmentation, you get bigger and more beautifully shaped breasts, with the added benefit of contouring fatty-areas of your body.
  • Hybrid breast augmentation: If you’re looking to have the best results possible, you might want to get breast implants to make your breasts bigger along with fat transfer to refine and contour them down to the finest detail.

Should I be concerned if I have micromastia?

Having small boobs is usually a cosmetic concern and does not cause any medical problems. However, in some cases, there may be an association to a congenital or genetic condition like; congenital adrenal hyperplasia, Turner syndrome, or Poland syndrome, which might warrant further investigation. Aside from the cosmetic and medical concerns, having small boobs can be annoying, it can affect several aspects of your life. Often, women with small boobs lose self-confidence in their body image, so they tend to withdraw from intimate situations and avoid wearing revealing clothing. If your boobs are very small, you might also have trouble finding bras that suit your body shape, or dresses that won’t droop around your neck when you wear them. This all can be very uncomfortable and may lead to you considering breast augmentation.
