Breast cancer happens to be the most common cancer among women over the age of 20. Mutations in the BRCA1 and BRCA2 genes cause approximately seven percent of breast cancer cases and up to 15 percent of ovarian cancer cases. Among women who test positive for BRCA1 and BRCA2 mutations, there’s up to an 87 percent chance of being diagnosed with breast cancer and 44 percent chance of being diagnosed with ovarian cancer.
Some celebrities have chosen to have double mastectomies when they realized they had the “faulty gene” BRCA1. In some cases, this lowers the chance of developing breast cancer all the way down to five percent. About six million women nationwide said they would seek medical advice on preventative surgery after hearing of celebrity procedures.
There’s no question that celebrities can take action that catches people’s attention. London Breast Institute figures showed genetic testing for BRCA mutations at their clinic had risen 67 percent since celebrities brought the issue into the spotlight.
