No. Inheriting a harmful gene change means that you have an increased risk for cancer, but it does not guarantee that you will develop a cancer in your lifetime. If testing shows that you have an increased risk for cancer, you may need to be screened earlier or more often. For example, if you have a change in the BRCA gene that increases your risk ...
Your health care team may recommend genetic testing based on guidelines established by the National Comprehensive Cancer Network (NCCN). These guidelines use factors such as your personal cancer history, family cancer history, ancestry or the presence of abnormal cells to determine if you qualify for genetic testing. If you do not meet the NCCN gui...
If you are battling cancer, genetic testing can help your care team make recommendations for treatments and surgical procedures.

Mar 6, 2024 · This week, 23andMe released new reports on three of the most common types of cancer — breast cancer, prostate cancer, and colorectal cancer. The new reports use thousands of genetic variants associated with the disease to assess a person’s likelihood of an individual developing one of these cancers. The reports are based on statistical ...
Apr 14, 2020 · Overview. Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease. Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are ...
Mar 21, 2019 · Currently, 23andMe screens for three mutations of the BRCA1 and BRCA2 genes, which are associated with a higher risk for breast, ovarian and prostate cancers. Here’s the caveat: If a person’s results come back positive for these genes, it does not always mean they will develop cancer. “Not everyone who has the BRCA1 or BRCA2 gene will be ...
