what is the genetic recurrence of breast cancer?

10-15% Hereditary: We believe that only 10-15% of breast cancers are hereditary, with the rest being environmental in origin. People w/the hereditary form of breast cancer tend to get diagnosed earlier in life and may get cancer in both breasts. When treated by lumpectomy or (single) mastectomy, it is not uncommon to develop a second, unrelated breast cancer; therefore, many opt for double mastectomies.
