Tracey Barraclough made a grim discovery in 1998. She found she possessed a gene that predisposed her to cancer. “I was told I had up to an 85% chance of developing breast cancer and an up to 60% chance of developing ovarian cancer,” she recalls. The piece of DNA responsible for her grim predisposition is known as the BRCA1 gene.
