Do I have a mild case of tubular breasts? I'm 21 years old. (Photos)

There are several features seen in tuberous breast deformity. Poorly defined inframammary fold, narrow breast width, areolar enlargement and constricted breast tissue. You may have some features similar to tuberous breast, ultimately an examination will helpful in answering your question definitively.

Tuberous breast is not, technically speaking, a "yes" or "no" question. There can be different points on the continuum. The typical hallmarks include a high, tight fold with "puffy" or distended areola, minimal breast tissue and potentially herniation of the breast tissue through a tightened ring thus the "tuberous" label. It is a congenital deformity which usually manifests at puberty. To what degree it manifests will vary from one patient to the next.
Treatment of tuberous breasts varies depending on the degree of the breast architectural distortion. Surgical correction typically involves:
-areolar reduction
-submuscular augmentation
-release of constricted breast tissue
All of these techniques work in concert to correct the tuberous deformation of the breast.
Based upon your photos alone, you do exhibit some features of a tuberous breast. However, this is difficult to discern via photos alone. There is no substitute for an in-person exam. If tuberous, this could be addressed via augmentation and radial parenchymal scoring.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Dear countrywild2638,tuberous breasts are not simply small or underdeveloped breasts. The appearance of the breast can range from mild to severe, and typical traits include: enlarged, puffy areola, rather wide spacing between the breasts, very little breast tissue, sagging, higher than normal inferior breast fold, and narrow base at the chest wall.
Its impossible to tell without a physical examination. I would discuss in consultation with a plastic surgeonDaniel Barrett, MD, MHA, MS

Hello and thank you for your question.   You appear to have mild tuberous breasts, in addtion to ptosis and asymmetry.  You are a great candidate
for a breast augmentation.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.   Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.   The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

If you are unhappy with the shape of your breasts there are many options available to you these days to correct them.  The diagnosis is less important than the fact that you are unhappy with how they look and it is important for you to know this can be improved.  Based on your pictures there does appear to be some constriction of the lower part of the breast - this could be described as a mild case of tuberous breasts.  Correction usually involves placing implants and making some adjustments to the breast tissue and often nipple position.  

Your breasts are wide set and you do appear to have a mild tuberous charasteristic.  I believe an augmentation would help both with volume and shape.

Thanks for your inquiry and pictures.  I believe you have mild tubular breast with a tight crease, but minimal glandular herniation into the areola, hope that helps best of luck.  

countrywild2638.  It appears from your photos that your inframammary folds are slightly constricted, or tight, but you do not have constricted breasts.  Breast augmentation and possible release of your folds should suit you nicely.  Be sure to consult with a board certified plastic surgeon. Good luck!

from your photos you have a constricted breast. The distance from the areola to the fold appears short thus causing the hanging appearance. A breast lift with implants would help with the appearance.

Hello, your breasts do not have typical tuberous features in my opinion.  The areolae are lower on the breasts (ptotic) but don't have some of the common findings such as nipple-areola pseudoherniation (protruding out from the the breast mound), constricted breast base, etc.
