A new study says that women with silicone breast implants may develop a rare form of lymphoma.

The study has been published in the Nov.5 issue of the Journal of the American Medical and its Dutch authors say that the absolute risk of developing this rare form of lymphoma is quite small and it can appear in 0.1 to 0.3 per 100,000 women with silicone implants every year.

Dr. Mitchell Smith, who is head of the lymphoma service at Fox Chase Cancer Center in Philadelphia, says: “Doctors must keep this fact in mind, however, women shouldn’t worry about it, as women with implants have one in many hundreds of thousands or even one in million chances to develop that cancer.”

According to Smith, this finding may prove helpful for scientists to understand the biology of this specific malignancy.

There have been controversies regarding Silicone breast implants for quite long time. The US Food and Drug Administration lifted a 14-year ban on Silicone breast implants commercial use in 2006 and gave approval to two companies to market the implants to all women aged 22 and older.

In 1992, the implants were removed from the market, as there were suspicions that they might cancer or some other autoimmune diseases. Similarly, there were other concerns that implants might obstruct with the preciseness of breast cancer screening, or broken tissues could cause other health problems.
