SILVER SPRING, MARYLAND — U.S. Food and Drug Administration said on Tuesday that nine deaths from a rare form of cancer have been linked to breast implants.

The cancer is known as Breast Implant-Associated Anaplastic Large Cell Lymphoma. It usually develops in the effusion fluid surrounding the breast implant or is contained inside the fibrous scar capsule, according to the FDA.

The condition is not a type of breast cancer, but a rare cancer of the cells of the immune system that can also occur in other parts of the body, including the skin and the lymphatic system.

Women with breast implants have a very low, but increased risk of developing cancer than women who do not have breast implants.

The FDA received a total of 359 reports of breast Implant-Associated Anaplastic Large Cell Lymphoma as of February 1 this year.

The authority has emphasized that the cancer is rare and the type of implant fill does not appear to affect the risk of developing the cancer.
