Hollywood actress Angelina Jolie has undergone a double mastectomy to reduce her chances of getting breast cancer.

The 37-year-old mother of six has explained her reasons for having the surgery in the New York Times.
She said her doctors estimated she had an 87% risk of breast cancer and a 50% risk of ovarian cancer. "I decided to be proactive and to minimise the risk as much I could," she wrote.
She said the process began in February and was completed by the end of April.
