Ask-the-Expert Online Conference

Question from CindyM: How do the genes tested in the MammaPrint and Oncotype DX differ from the BRCA1 and BRCA2 genes?
Answers - Carol Cherry, M.S.N., R.N., A.P.R.N., B.C. Oncotype DX is a panel of 21 genes that indicate the recurrence potential of a breast tumor. It is used in particular cases of breast cancer, particularly early stage breast cancer, to help decide if women would benefit from chemotherapy or not. These genes are different than the BRCA1 and BRCA2 genes, which are tumor suppressor genes that are passed through families and predisposed to the development of breast cancer.

The Ask-the-Expert Online Conference Breast Cancer Risk and Your Family featured Terri McHugh, D.O., and Carol Cherry, M.S.N., R.N., A.P.R.N., B.C. answering your questions about genetics and breast cancer, and how your family could be affected.
