With the help of her family -- the very daughters who tested positive for the BRCA gene -- Marietta Drucker also came to terms with her guilt.
"As a mother, I understood why she was feeling so guilty," says Drucker's daughter Debbie Sokolov, a cancer survivor who after she was diagnosed with breast cancer began to speak out publicly with her mother about BRCA screening while working for Facing Our Risk of Cancer Empowered, a nonprofit that focuses on people affected by hereditary breast and ovarian cancer.
"But what's amazing, what we kept telling her, is that she saved our lives," Sokolov says. "Knowing I had the gene meant I was able to make the right decisions. She has nothing to feel bad about. I'm alive today because of her. She's my hero."
