Whenever possible, genetic testing should be performed on the person in the family who is most likely to have a BRCA1 and BRCA2 mutation or other type of hereditary cancer syndrome. If a mutation is found in that person, genetic testing can then be offered to family members without cancer to determine their cancer risks.
It is important to understand that positive genetic testing does not mean that cancer is inevitable. If a woman does test positive for a mutation, there are some steps she may want to take. There are the options of more rigorous screening, preventive medications as well as removal of the ovaries and/or breasts in order to decrease her cancer risk.
On the other hand, negative genetic testing does not mean that a person will never develop cancer. In some cases, negative genetic testing may not even lower breast or ovarian cancer risk if other factors, like a strong family history, are still present.
Genetic testing for hereditary cancer can be complex. As such, it is important to speak with a trained genetic professional who can discuss the risks, benefits, and limitations of all genetic testing options as well as any possible screening and preventative measures.
