Angelina Jolie just became part of a medical trend: More women are deciding to have their breasts removed to reduce the risk of cancer.
Over the past decade, doctors have noticed a big increase in the number of women choosing prophylactic, or preventive, mastectomies.
Some, like Jolie, have a genetic mutation that makes it much more likely that they will have breast cancer. Her mother died of the disease at age 56. Jolie is 37. She wrote about her decision in The New York Times.
