During your appointment, a member of the team will confirm your family history/ family tree details with you and may ask about other medical conditions in your family (where known).
If a cancer genetic alteration (gene fault) exists in your family, or there is a possibility of an inherited genetic alteration, our team will discuss the condition and outline the choices and options available to you.
What is ‘Diagnostic Cancer Genetic Testing’?
Diagnostic cancer genetic testing is helpful when an individual with cancer is unaware of whether a gene alteration is present within their family. A blood test can be taken either from you or an eligible family member (i.e. the blood test must be taken from someone with cancer), to identify any alteration (gene fault) in your DNA. If a cancer gene alteration exists, it may be responsible for causing cancer in you, and/ or in other family members.
What is ‘Predictive Cancer Genetic Testing’?
If a cancer gene alteration is identified in your family, you may opt to undergo a predictive cancer genetic test to determine if you carry your family’s alteration, using a blood sample taken from you.
