Do I have a tubular breasts? (Photo)

Your photos suggest that any potential irregularities are so mild that nothing other than a standard breast augmentation would be necessary or recommended. Confirm this with your surgeon during a consultation, as he or she will have the benefit of a physical examination of your tissues and can give a more definitive diagnosis and recommendation.

More like a herniated nipple-areola complex than a tuberous breast. Since the nipple position is pretty high on the breast, but the breast is just small, options include surgery to correct the excess protrusion and potential volume addition with either an implant or fat grafting.

Its hard to tell with just one pic from the side, however you most likely have a constricted skin envelops and there is some herniation of breast tissue under the nipple causing a "puffy" nipple.

A full set of photos and exam are really needed to make the call however your case would require a little extra thought when selecting the size and shape of an implant as you likely do not have enough skin to cover a large implant (which could damage your tissue and cause an unfavorable result)
