What is the risk of trauma to the muscle after removal of breast implants?

Hello. I am 32 years old without children. I had to remove the breast implants. I completely expired in 15 days in Italy. The surgeon proposed to remove the breast implants and the capsule through the nipple. the prostheses are a month behind the muscle. he says that he will open the fibers of the muscle and clean the rib cage. The truth is that I am afraid. And can I do this kind of intervention? Will the muscle suffer? And better if I propose to do the cut under the breast? I hope you answer me.
