How can I tell if there’s a faulty gene in my family?

Only 2 to 10% of cancer is caused by “faulty genes”.

If an important gene isn’t working properly because of an inherited change (referred to as a mutation), then the risk of certain cancers may increase.

If this is the case, then there may be more cancer, rare cancers or cancers occurring at a younger age than average.

Determining your family cancer history or pedigree can be very useful in determining what is going on in your family
