Can Breast Cancer Skip Generations?

The inheritance of breast cancer accounts for less than 5% of all known breast cancers. Furthermore, even the presence of the gene(s) associated with breast-cancer risk is a poor predictor of whether the individual will get breast cancer.... In other words, even if you inherit the brca gene, which is the gene involved with many of those 5% of breast cancers, it does NOT mean you will get breast cancer...Furthermore, NO one can accurately predict whether a single person carrying the gene will get breast cancer.
