Breast augmentation involves the improvement of appearance & enlargement of your breasts. The operation involves the insertion of an implant which consists of soft or cohesive gel, silicone contained in a silicone bag. The implants are placed either behind or in front of the pectoralis major muscle which lies under the breast itself.
In most of the cases the implants are placed in between the mammary gland and the muscle. Only in a few situations, like lack of enough breast tissue to cover the implants, the implants will then go under the muscle, this is to offer some coverage and disguise better the implants.
It should not interfere with the diagnosis or treatment of any future breast disease, and there is no relation with silicone implants and breast cancer.
