Breast cancer is genetic and not hereditary, is that correct?

Basic biology: It's easy to misunderstand. Genetic disease is usually hereditary -- only a few diseases of genes can't be inherited or passed on; new mutations are genetic but not hereditary. Inherited disease is almost always genetic. A variety of genes may be passed parent-to-child, each defining a "cancer family syndrome" but most cancer is sporadic.

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.

Sometimes.: It is estimated that 10-15% of all breast cancer cases in the us occur due to hereditary factors. This risk may be identified by doing a simple blood test to check for brca mutations. We generally advise testing family members with known breast cancers first before checking unaffected family.
