Angelina Jolie's dramatic decision in 2013 to have a preventative double mastectomy raised awareness around the world of the importance of genetic testing for cancer. She reached the decision after tests revealed the presence of a mutated gene that predisposed her to breast cancer.
Researchers responded by trying to understand the influence that Jolie's bold decision had on other women in getting tested for breast cancer, especially women with high hereditary risk. There was also research on whether having both breasts removed really is beneficial for women after a tumor is discovered in one.
The "Jolie effect" (as researchers call it) has made more women aware of genetic testing. But when should such testing be done? And are insurance companies dragging their feet in paying for it?
