Approximately 5 – 10% of pancreatic and prostate cancers can be linked to inherited changes in genes that help protect our cells from cancer. When one of these gene changes (also called a pathogenic variant) runs in a family, the risk of developing certain cancers can be higher than average.
Genetic testing can help identify whether an inherited condition is present. This information may support earlier or more tailored screening, guide treatment decisions, and help family members understand their own cancer risks. Testing is usually considered when there is a personal or family history of pancreatic cancer, prostate cancer diagnosed at a younger age, multiple relatives with related cancers, or a known genetic condition in the family.
Not everyone with a gene change will develop cancer, but identifying a genetic cause can be important for risk‑appropriate care.
Testing may be recommended if you or a close family member has had pancreatic or prostate cancer, especially if the diagnosis occurred at a younger age, if there are multiple affected relatives, or if there is a history of related cancers such as breast, ovarian or colorectal cancer.
Genetic testing typically involves a blood sample. The sample is analysed in the laboratory to look for inherited changes in genes linked to cancer risk.
If testing identifies an inherited gene change, this information may help guide cancer screening, risk management, and treatment options. It can also be useful for family members, who may choose to seek testing themselves.
Yes. Genetic testing can be just as valuable after a cancer diagnosis, as it may inform treatment decisions and help clarify cancer risk for relatives.
