In the U.S., getting breast augmentation surgery -- breast implants for cosmetic reasons -- cost an average of $5,278 in 2011.
Most women have to pay that out of their own pockets. Insurance usually will not cover breast enlargement surgery. It will, though, cover breast implants for women who have had mastectomies due to breast cancer.
If you need further surgery later on, your health insurance may not cover that, either. Having breast implants may also affect your insurance rates later on.
