For nearly three decades, the safety of silicone breast implants has been debated and investigated, 10News reported. During the past 10 years the Food and Drug Administration investigators looked at whether the implants were associated with connective tissue or cancer. After a rigorous review, the FDA determined they were safe and approved the sale of silicone gel implants again. Twenty-two-year-old Tiana Damico used to have more of a boyish figure. She knew breast implants would help with that, but she wanted to look natural. "I didn't want any rippling with the salines so I opted to wait," said Damico. Damico is among a growing number of women who were waiting to see if silicone gel breast implants would receive a clean bill of health from FDA investigators. "The new implants are designed very differently than the ones from 20 years ago," said plastic and reconstructive surgeon Dr. Munish Batra. The recent approval has allowed two companies to sell silicone gel breast implants. "The silicone feels a lot more natural, feels more like tissue," said Batra. "This new and improved silicone implant is not only perkier in profile, it's less prone to rupture and leaking and it can last a lifetime," said Batra. "The new and improved version has a three-layered shell so that you don't get the silicone gel bleed so if you don't get the bleed, you don't get the leakage, you don't get the rupture," said Batra. The new silicone gel implants won't ripple, like what happens with saline implants. "Because the saline liquid is thinner or less viscous, the implant can fold on itself and cause rippling, and that you don't see with a gel implant, said Batra.Batra said since the FDA approval, a lot of women are asking for the new implants. "I think these implants can last a lifetime," said Damico. "I knew I wanted the best and I waited." Damico felt confident her implants are safe and look more natural. Even though the silicone implants were determined to be safe and effective, the FDA is requiring both companies who make the implants to follow 40,000 women for 10 years to check for any problems.If you would like to read more about the FDA decision, click on http://www.fda.gov/bbs/topics/news/2006/new01512.html.
