Book excerpt: It was no coincidence. There were too many cancer diagnoses in the Tropea family to be coincidental, and Diane Tropea Greene knew it. Apron Strings is the painful but courageous story of Diane and her family, a family that was decimated by cancer. Diane learned that her cancer was caused by the BRCA2 gene mutation for breast cancer, which affected both the women and men in Diane's family. Knowledge is power, however, and the lesson of the Tropea family is important for anyone who suspects their family has too many cancer diagnoses to be coincidental.
