And a negative result does not mean that you will not develop cancer.
When a person is ever concerned that they have inherited a cancer susceptibility syndrome in their family, it’s best that a family member who has cancer has genetic counseling and testing first in order to know whether the cancer is because of an inherited genetic variant. Also, genetic testing is more informative when it starts with a family member who has a current or previous cancer diagnosis compared to someone who has not had cancer.
When a person in the family was found to have inherited cancer susceptibility syndrome, any family members who have inherited it needs to get genetic testing even when they have never had cancer before.

The test also screens for markers of any inherited cancer risk such as BRCA1 and BRCA2, which are actually linked to breast cancer.
The genetic tests also could help in identifying mutations that may lead to insidious enzyme deficiencies. A good example, in this case, is when there’s an enzyme deficiency which is called MTHFR. This kind of enzyme is responsible for various biochemical reactions in one’s body that includes the B12 assimilation and the regulating detoxification pathways. The low-level enzyme will create havoc towards a person’s health, which then causes various problems.
