WASHINGTON (AP) — Federal health officials say the latest data on silicone breast implants show they are relatively safe, despite frequent complications that lead about one in five women to have the implants removed within ten years.

A Food and Drug Administration report issued Wednesday is the agency’s first safety assessment of the devices since regulators returned them to the market in 2006. That followed a 14-year ban when only saline-filled implants were widely available.

The most common side effect remains scar tissue which hardens around the implant, warping the shape of the breast. Other problems include implant rupture, wrinkling, and lopsided appearance, according to the report.

“Despite frequent local complications and adverse outcomes, the benefits and risks of breast implants are sufficiently well understood for women to make informed decisions about their use,” the agency concludes.

The findings are primarily based on follow-up studies conducted by the two U.S. manufacturers of the devices, Allergan Inc. and Johnson & Johnson’s Mentor unit.

But industry critics point out most of the studies are incomplete, and many women have already dropped out.

For example, only 58 percent of women enrolled in a 1,000-patient study of Mentor’s implants are still accounted for after eight years. Two larger studies of 40,000 women, conducted by both Allergan and Mentor respectively, have each lost a significant number of patients after just two to three years.

Dr. Diana Zuckerman of the National Research Center for Women and Families said most medical journals would not publish the studies cited by FDA because of the missing data.

“Once a medical product is approved, the manufacturers have no incentive to do these required studies properly,” Zuckerman said.

“So, we end up with useless information, which is what has happened with the largest, most important studies of silicone gel breast implants.”

The FDA commented that “both manufacturers have communicated to the FDA the difficulties in following women who have received silicone gel-filled breast implants.” The agency said it is working with Allergan and Mentor to increase participation and follow-up.

Based on the company data, FDA says 20 to 40 percent of patients who have implants for cosmetic reasons will need another operation to modify or remove them within eight to 10 years. For women with implants for breast reconstruction the number is even higher, at 40 to 70 percent.

Breast augmentation remains the most popular cosmetic surgery in the U.S., with nearly 300,000 women receiving saline or silicone breast implants last year.

The FDA pulled silicone breast implants off the market in 1992, saying manufacturers had not provided medical data showing their safety and effectiveness. At the time, there were worries about a connection to a variety of diseases, including cancer and lupus. Alarming cases of ruptures added to the concern.

But in 2006 the agency returned the implants to the market after most studies failed to find a link between silicone breast implants and those diseases. Patients and plastic surgeons say the silicone-filled implants look and feel more real than saline versions.

The approval came with conditions, including a requirement that the companies complete 10-year studies on women who have already received the implants to study leaks, as well conduct new decade-long studies of the safety of the devices in 40,000 women.

    I see no need for slicone implants. Women are beautiful the way God made them. Their is no need to cater to the men who are only attracted to bigger breast. If this is what you are being judged by then you don’t need that type of person in your life. I blame men for this as you now have women risking surgery, infection and sometimes their life to get implants. Love em the way the are cause natural is the best!

        So you don’t mind women taking unnceccesary risk to get implants to satisfy your fetish? So it would be ok for your daughter or sister to get implants so they could meet a “REAL” jerk. Now get back to your porn site!
