“Is breast cancer genetic?”
Is it possible for breast cancer to be in someone's genes? Does it meant that I can get it if my mother had it?

About one in ten breast cancers can be transmitted genetically (from family), so most breast cancers aren't passed on to offsprings. Depending on the age of diagnosis of breast cancer, there may be a need for genetic testing, looking for abnormal genes (mutation of the BRCA gene). If such mutation is found, the lifetime risk of developing breast and ovarian cancer, along with some other cancers, becomes very significant.
