A long-term study of women with breast implants shows no support for newly expressed concerns about a cancer risk, and 25 years of experience also shows implants are safe, plastic surgeons say.

"We certainly wouldn't do it (implant surgery) if we thought there was a significant risk," said George Reading, president of the American Society of Plastic and Reconstructive Surgeons.An estimated 2 million women have received implants, with 130,000 procedures done every year. Most are for cosmetic purposes, and the rest for reconstruction after breast surgery.

The Public Citizen Health Research Group, a private health advocacy organization, called this week for a ban on implants, which they said may give a risk of cancer and other health problems.
