Do I have tubular breast? Is it severe? What can I do about it? (Photos)

tc321.   It appears from your photographs that your breasts are tuberous with some asymmetry and ptosis. However nice improvement can be attained with breast lift/areolar reduction  with implants and release of the tight tissue of your lower breasts. Be sure to consult with a board certified plastic surgeon with lots of experience with tuberous breast surgery.  Good luck!

Thank you for the question and pictures.
I think your breast photos do demonstrate some of the characteristics seen with tubular (constricted) breast. For example, the distance from the areola to inframammary folds seems to be tight and relatively short. Your inframammary folds seem to be widely spaced from the midline of your chest. The areola do demonstrate some features associated with tubular breast such as an increased width and “puffiness”.
Generally, correction of tuberous breast anomalies involves breast augmentation with areola reduction / mastopexy procedure. The distance from the inframammary fold is increased (to create a more rounded out appearance). Proper implant positioning improves the distance (cleavage) between the breasts. The areola reduction helps to treat the pointed and "puffy" appearance of the areola.
In your case, if the appearance/shape/size of the breasts are a concern, you may be an excellent candidate for corrective surgery.
When you are ready, please make sure you consult with well experienced board-certified plastic surgeons who have significant (demonstrable) experience with this type of surgery. There are a lot of factors to consider when making recommendations; for example your life circumstances ( planned pregnancies, psychosocial situation…) and tolerance for scars are factors that should be taken into consideration by you and your plastic surgeon.
I hope this helps. Best wishes.
