Men who test negative for a known breast cancer gene abnormality have the same very low risk of developing breast cancer as men in the general population. Whether you are a woman or a man, testing negative also means that you could not have passed the genetic abnormality on to your children.

Genetic mutations can have harmful, beneficial, neutral (no effect), or uncertain effects on health. Mutations that are harmful may increase a personâs chance, or risk, of developing a disease such as cancer.
