Growth away from under nipple?

[Ron15]

If you had gyno surgery and there was residual gland left - could that still grow if it was away from under the nipple? Im sure ive got this happening on my upper chest years post op now

[Dr. Sasson]

Depending on hormonal changes and weight changes sometimes the tissue can grow back.

[Dr. Schuster]

Sometimes there can be "accessory" breast tissue. Usually this is in the upper chest towards the armpit. If the major breast tissue in the center has been removed this might cause a slight increase, either real or relative, in the appearance of the accessory breast tissue.
