Silicone breast implants and breast cancer

Four hundred and seventy-five women with silicone breast implants were matched with control groups and reviewed for evidence of breast cancer. No increased risk of developing breast cancer was found in women who had received a silicone breast prosthesis following breast augmentation compared with the expected incidence in this age group. In women who had a breast reconstruction using a silicone breast implant following mastectomy for breast cancer, there was no increased rate of recurrence, either locally, regionally or at distant sites, or a decrease in survival compared with matched controls.
