Triangular shaped breasts with large, hanging nipples that I can't reshape with a bra. Are they tubular? (photo)

Your breasts a slightly tuberous and ptotic, or saggy.  You would be a good candidate for a lollipop lift with implants if you want to correct it properly.

  From your description, there may be components of tuberous breasts, but I cannot reliably interpret the photo presented.Kenneth Hughes, MDLos Angeles, CA

Hard to tell because of the quality of the picture. However, you have elements such as a constricted base, some droopiness and deficient tissue in your lower pole, see a local doc to discuss! 

You do have some characteristics of that but are not classic tuberous.  Regardless, if you wish to rejuvenate them and make them rounder and perkier, you will need an augmentation and a lift.  Find a local plastic surgeon to listen to your concerns and then see what your surgeon can deliver then decide if its for you.

Thank you for the question.To best help you, a physical
examination or another picture where your breast actually show is required in order to determine which procedures and
techniques wold be best for your case.Dr. Campos
