Through a genetic analysis of blood can detect hereditary risk of developing cancer. The test determines whether people are carriers of a genetic alteration associated with this disease may, if so, take preventive measures or early detection.

In most cases where the cancer is not hereditary. The fact that there are several precedents in a family does not mean that there is a hereditary cause. Just suspect if one or more of these cases:• Three or more first-degree relatives (parents, children and siblings) or second degree (grandparents and uncles) diagnosed with cancers of the same organ or associated organs: breast and ovarian cancer; or colon and uterus.• Two or more first- or second-degree diagnosed with cancer at a younger age than usual. For example, breast cancer before age 40, colon cancer before age 50 or prostate cancer before age 60.• When cancer affects two organs of a person bilaterally. For example, both breasts or both kidneys.• When there is a related syndrome in the family with an inherited predisposition to cancer. For example, Lynch syndrome or familial adenomatous polyposis.

When any of these conditions is met, you can be performed genetic analysis and find out what people are carriers of the family and what people are free from it. If you have the genetic alteration are informed of the measures of prevention and early diagnosis that can be taken, the probability of transmission to offspring and if they want to have children, not to transmit options. When a family no alteration is detected, they advise them based on their family medical history, personal and.
