Mutations of the BRCA1 and BRCA2 genes have been linked to the development of hereditary breast and ovarian cancer
. About 60 percent of women (6 out of 10) who have inherited a harmful mutation in BRCA1 or BRCA2 will be diagnosed with ovarian cancer.
RED FLAGS for Hereditary Breast and Ovarian Cancer
Syndrome include a personal or family history of these:
An AstraZeneca spokesman said development was still at the "very early stages" but that it was envisaged the compound could be used to treat woman with hereditary breast and ovarian cancer
Scientists already know that inheriting faulty BRCA genes can trigger hereditary breast and ovarian cancer
, but they did not know what role these genes had in sporadic cancer.
The most prevalent hereditary syndromes associated with these tumors (Table) are hereditary nonpolyposis colorectal cancer (HNPCC), familial adenomatous polyposis (FAP), hereditary breast and ovarian cancer
(HBOC), and multiple endocrine neoplasia type 2 (MEN 2).
Several syndromes are known to be involved in the development of breast and ovarian tumors such as hereditary breast and ovarian cancer
syndrome, Li-Fraumeni syndrome, Cowden disease, hereditary non polyposis colon carcinoma (HNPCC), and Peutz-Jeghers syndrome (6).
NSGC practice guideline: risk assessment and genetic counseling for hereditary breast and ovarian cancer

This is particularly concerning in the context of single-gene disorders such as hereditary breast and ovarian cancer
syndrome, in which a mutation in either the BRCA1 or BRCA2 gene confers up to 50%-60% lifetime risk of female breast cancer and up to 40% lifetime risk of ovarian cancer-as well as increasing the risk of female primary papillary serous peritoneal carcinoma, male breast cancer, prostate cancer, and pancreatic cancer ("BRCA1 and BRCA2 Hereditary Breast and Ovarian Cancer

Washington, May 28 (ANI): A study has reported new insights into the pathogenesis and treatment of hereditary breast and ovarian cancer
and newly discovered risk genes.
