Angelina Jolie
IN 2013, actress Angelina Jolie made headlines by announcing that she had decided to have a double mastectomy as a preventative measure against a hereditary form of cancer. Sadly, Jolie had previously lost her mother, grandmother and aunt to this same type of cancer—linked to a mutation in the BRCA1 gene—and knew that her risks were extremely high. So, in a bold and somewhat controversial move, Jolie took preventative steps before the cancer ever fully developed.
