Jadin Wilson, 3, stands at a Boulanger family party with her grandmother Hope Sonney (background in pink) and her great Aunt Heather Christian (left). Both women and their sisters carry the BRCA1 gene mutation that puts them at extremely high risk of breast and ovarian cancer. Heather and Hope are having preventative mastectomies. "This little girl," says Heather, "I want to see her grow up and have children." Photo: Rob Finch
