Breast Cancer Panel
Breast cancer, the most common cancer in women, is a disease in which carcinomas arise from epithelial cells in lobular and duct tissues in the breast. Breast cancer affects about 1 in 8 (~12.4%) women on average over the course of their lifetime. It accounts for 1/3 of the cancers in women and in 2017, it is estimated that approximately 255,180 new cases will be diagnosed. Most cases of breast cancer occur sporadically, or without family history. However, about 5-10% of the cases are hereditary and frequently associated with ovarian cancer and other types of cancer. Genetic testing facilitates the identification of hereditary breast cancer, alerts the patient about risks of having other cancers, empowers patients to make their medical decisions and provides information for other at-risk family members. This test analyzes 19 genes simultaneously, including both high-risk genes (BRCA1, BRCA2, CDH1, STK11, PTEN, TP53) and other moderate-to-high-risk genes, which will affect the medical management based on clinical guidelines.
- Genes (19): BRCA1, BRCA2, TP53, PTEN, CDH1, STK11, ATM, AR, BARD1, BRIP1, CASP8, CHEK2, DIRAS3, ERBB2, NBN, PALB2, RAD50, RAD51C, and TGFB1
