An estimated 025 of the general population carries a mutated BRCA gene or about one out of every 400 people. The decision to be tested may be very difficult for some men says Corbman.

Your doctor might suggest testing using a multigene panel which looks for mutations in several genes at the same time including BRCA1 and BRCA2. In the interview Applegate also advocated for women to get tested for BRCA gene mutations which increase the risk of developing breast and ovarian cancer cancer. If your mothers sister has an abnormal BRCA or PALB2 gene the next person to be tested would be your mother.

If her test is negative no gene abnormality present then you do not need to be tested because she could not have passed the mutation on to you. Tests are available to see if someone has inherited a harmful variant in BRCA1 and BRCA2. To test for a somatic BRCA mutation your doctor or genetic counselor will collect a tissue sample from your tumor to test the DNA.

Once your doctor or genetic counselor receives the results he or she will inform you of your BRCA status. But many women are scared to get the test because theyre afraid to learn they carry a BRCA mutation. Men should consider being tested for BRCA mutations under the following conditions.
