Regrowth of chest tissue after surgery a decade ago upon starting finasteride. Will another surgery solve this permanently?

I thought I solved this problem years ago with successful surgery. Now, after recently starting finasteride (all four grandparents were bald or had severely thinning hair by age 60, dad bald at 20, mom has gotten scalp shots at 35, hair replacement at 50), the fin is working but my chest tissue is growing back as an awful side effect! Can a second surgery solve this for good? Btw, both men and women have died of breast cancer in my family, so it's a health and cosmetic concern.
