Rare Mutations May Not Always Spur Breast Cancer on Their Own

Results of a new laboratory study suggest that some rare “missense” mutations in the HER2 gene are apparently not — on their own — capable of causing breast cancer growth or spread. In a related finding, the Johns Hopkins research team said such mutations, which are found in about 5 percent of breast cancers, may, thus, also fail to predict response to anti-cancer drugs…(Read the full story)
