I have a double mastectomy with no reconstruction. I'm lean with a BMI of 21, so lean that my ribs show. I like the rest of my body just fine the way it is and am physically active. If I don't have enough belly fat to make two breasts, are there other options for autologous reconstruction that will not hurt my ability to dance, have sex, lift weights, etc.? Which offer the least scarring? I had open-abdominal fibroid-removal surgery about 15 years ago but I hear this need not rule out a DIEP.
