Do I have tubular breasts? Are they just small? (Photo)

You do appear to have some mild constriction of tissue around your nipples, a trait of tuberous breasts. If they aren’t causing you any issues, there is no need to pursue surgery to release the constricted tissue.

Tubular breasts are characterized by a number of features, including an under developed lower pole (area below the nipple), herniated nipples (which can appear large), a high IMF (fold under the breast). This is important to recognize features of tubular breast prior to undergoing any type of breast enhancement procedure, as there are specific techniques that can be employed during breast enhancement procedures to correct each of these characteristics.

Thanks for your inquiry, you do have tubular breast, it does need to be "fixed". If you desire a change in shape or size, I recommend consultation with a board certified plastic surgeon.
