What exactly makes breasts tuberous and what are the different types? Can breasts become tuberous over time? (photo)

Based on your photo, you don't appear to have tuberous breast anatomy. You do appear to have a somewhat foreshortened and ill-defined infra-mammary fold. The good news is that breast augmentation, when done properly, will create a more defined infra-mammary fold for you. Make sure you meet with an experienced plastic surgeon before embarking on this procedure.

Hello,Thank you for your question and photo. To me, it does not appear that you have tuberous breasts. you may have a short nipple-to-fold space but this is perfectly normal. If you are interested in breast augmentation with breast implants you appear to be a good candidate. I recommend that you seek a board certified Plastic Surgeon to consult with. They will examine you and talk about your aesthetic goals, then make recommendations for treatment.All the best

Tuberous breasts present in different degrees of severity. Three hallmark features of tuberous breasts
include enlarged areolas, herniation of breast tissue through the areola, and a
constricted base. It is not clear to me
from your photograph whether or not you do actually have tuberous breasts. Best to discuss particular circumstances during
an in-person consultation. Best regards.

By looking at your above photo, you do not appear to have tuberous breasts. However, to better evaluate you and get a sense of what you are looking to achieve I recommend scheduling a consultation with a board certified plastic surgeon.  

Your breasts aren't tuberous.  Tuberous breasts are so named because they look like a tuber. For example, a a daikon.  

Based solely on your photos, you do not appear to have tuberous breasts. In fact, you look as if you will do very nicely with a breast implant alone. My best,

It would be impossible to comment without photos at a minimum and preferably a full exam. See a board certified plastic surgeon with experience with Tubular Breast problems. 

The tuberous breast is a developmental phenomenon that is essentially a hernia.  The investing  fascia that supports the breast tissue during growth and development is weaker and the breast tissue herniates forward instead of mounding on the chest wall in the desired hemispherical shape.  The areola, accordingly dilates from this uncontrolled herniation. The constriction is the ring of fascia that never became stretched.  Because your photographs appear to be taken with your arms raised it is deceiving. Indeed you may have a tight lower pole that may require lowering to achieve the desired shape.

Thank you for your question. These patients typically have a lower pull of the breast. In addition, they can have large areola and a short nipple ti inframammary fold distance. I hope you find this information useful.  

Based on the submitted photos you do not appear to have tuberous breasts. Tuberous breast usually has several different
characteristics that make the diagnosis. That being said, these findings are on
a spectrum of severity, with some people demonstrating mild changes and others
severe, and still others only show certain characteristics and not all
characteristics. Regarding weight loss, it seems you likely have good quality skin which has retracted/tightened down after the weight loss (this is a good thing - if not your breasts become extremely droopy!) I would consider a second opinion from a board certified plastic surgeon. Good luck!
