Normal cells in the body grow, divide, and are replaced on a routine basis. Sometimes, cells divide abnormally and begin to grow out of control. These cells may form growths or tumors.
Women who have inherited mutations in these genes are at an increased risk of developing breast cancer and ovarian cancer compared with the general population. The BRCA gene test is offered only to people who are likely to have an inherited mutation based on personal or family history, or who have a specific type of breast cancer. The BRCA gene test isn't routinely performed on women at average risk of breast and ovarian cancers.
There is no doubt that breast cancer can run in families. Just because one of your relatives had breast cancer does not mean you are absolutely fated to develop it. Your risk may be increased if your relative developed breast cancer at a young age or if the relative is very closely related, like a mother, sister or daughter.
Certain mutations in the BRCA genes make cells more likely to divide and change rapidly, which can lead to cancer. Some groups are at a higher risk for a BRCA gene mutation than others, including women with Ashkenazi Jewish heritage. Not every woman who has a BRCA1 or BRCA2 gene mutation will get breast or ovarian cancer, but having a gene mutation puts you at an increased risk for these cancers.
Skip to Content. The chance that a family has HBOC increases in any of these situations:. A woman is diagnosed with a second breast cancer in the same or the other breast or has both breast and ovarian cancer.
Lindsay Avner never met her grandmother or her great-grandmother. Before she was born, breast cancer claimed them both, the latter at age 58, the former on the cusp of turning The disease also struck her mother, as did ovarian cancer, though she survived both.
Mutations in these genes have been linked to a higher risk of breast cancer and ovarian cancer. Cancer is also more likely to develop at an earlier age. A genetic counselor can help you understand if you're likely to have an inherited susceptibility to breast or ovarian cancer.
Your genetic counsellor will discuss with you the different ways of reducing your risk of developing breast cancer. There are three options to consider - screening, risk reducing surgery and drug treatment. The choice will take into account your current health and the prognosis of your diagnosis of ovarian cancer. Women between the ages of 50 and 70 are typically invited for breast screening every three years, but women at high risk can access screening tests before the age of 50 and after the age of
Healthy women who carry a breast cancer-causing mutation in the BRCA1 gene, not only reduce their risk of developing the disease but also their chances of dying from it if they have both breasts removed, according to new research presented today Wednesday at the 11th European Breast Cancer Conference. However, the study also found that for women with a mutation in the BRCA2 gene, there was no difference in their chances of dying from the disease whether they opted to have their breasts removed bilateral risk-reducing mastectomy or BRRM or chose to have closer surveillance instead. The study of BRCA1 mutation carriers and BRCA2 mutation carriers in The Netherlands is the first to prospectively follow healthy women, who opted for either BRRM or surveillance, in order to compare their overall risk of dying from any cause and their risk of dying from breast cancer.
