Cancer Risk Assessment (Genetic Counselling)

Approximately 5-10% of all cancer is due to a genetic fault (mutation) which can be inherited through a family. Families with an inherited mutation may benefit from a cancer risk assessment (genetic counselling consultation), increased cancer screening and/or risk reducing strategies.

Families with an increased risk of cancer often show one of the following clues:

Several relatives with the same type of cancer

Relatives diagnosed at particularly young ages (usually before age 50)

Several affected generations

Individuals who have been diagnosed with multiple cancers

Hereditary cancer risk factors

In general, cancer can be caused by many different factors including family history, medical history and environmental factors. The exact risk factors depend on the type of cancer. For example, lung cancer is usually caused by environmental factors such as exposure to smoke, while cervical cancer often occurs at younger ages but is usually not inherited. 

Why would I want to know that I’m at risk of cancer?

For individuals with an increased risk of cancer, screening can often be beneficial in detecting cancer at an earlier stage. Depending on the specific risk, different cancer screening tests can be arranged and risk-reducing strategies considered.
