breast cancer gene panel testing

One vial of blood can shed light on a spectrum of predisposition and risk. It was agreed to include ATM and CHEK2, ... since mutations are associated only with a rare type of ovarian cancer—sex cord tumours with annular tubules—so testing on a gene panel primarily intended for individuals with epithelial ovarian cancer was not considered appropriate. NLM The clinical validity and utility of multi-gene panel testing is getting better characterized as more data on the significance of moderate-penetrance genes are collected from large, cancer genetic testing studies. Women with BRCA1 and BRCA2 mutations may pursue surgery to help prevent breast cancer, for example. Cancer risks and mortality in heterozygous ATM mutation carriers. Advances in sequencing technology have made multigene testing, or “panel testing,” a … Some people choose to undergo genetic testing to find out. "Simply having a proven gene abnormality does not necessarily mean that a woman will develop breast cancer, or that her cancer will be any worse than cancer that does not stem from an inherited genetic flaw. Background: Breast cancer (BC) is a highly complex, heterogeneous and multifactorial disease and is the most commonly diagnosed cancer and the leading cause of cancer–related mortality in women worldwide. Testing for these abnormalities is not done routinely, but it may be considered on the basis of your family history and personal situation. USA.gov. 2010).
