Hollywood actress Angelina Jolie has undergone a double mastectomy to reduce her chances of getting breast cancer.
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.
"but the truth is I carry a 'faulty' gene, BRCA1, which sharply increases my risk of developing breast cancer and ovarian cancer"
Her chances of developing breast cancer have now dropped from 87% to under 5%, she said.
