Cancer is a genetic disease that is either inherited or somatic. It is important to emphasize that hereditary cancer risk assessment is an important process. Genetic counselling is important for patients with suspected inherited risk and should be recommended before testing. Once a mutation is identified,the patient should be counselled regard-ing risk-reducing surgery, other risk-reduction strategies, and altered screening. Inherited cancer risk affects other family members, and counselling with testing should be recommended for other family members who are at risk.
