Sorry to hear about your problem. There can be some deformity
in the breast after surgery & radiotherapy due to ibrosis. Reconstructive surgery
is the only option by which this deformity can be corrected. It will involve cutting the fibrotic tissue and filling the defect by mobilising tissue from the breast or from adjacent tissue (muscle).
Getting this reconstructive surgery will make you feel better about yourself and more confident.
Hope you get well soon.
