Do you need a referral for a hereditary cancer panel test?

Access rules depend on the clinic and laboratory. Before booking, ask whether you need a referral from a family doctor, oncologist or another specialist, and whether genetic counselling is included before and after testing.

A hereditary cancer panel looks for inherited changes across multiple genes associated with cancer susceptibility. It usually uses a blood or saliva sample and is different from genomic profiling of tumour tissue. The panel should be selected to match your personal and family history rather than simply choosing the largest available list of genes.

A result may identify a harmful inherited change, find no relevant change or detect a variant whose meaning is uncertain. Each outcome needs careful interpretation. A negative result does not erase the cancer history in a family, and an uncertain variant should not be treated as a confirmed cause.

Collect details about cancers in close relatives, including the cancer type, age at diagnosis and which side of the family was affected. Bring your own pathology reports and any previous genetic test reports from relatives if they are available. You do not need to delay the appointment because some family details are missing.

During counselling, discuss what the test can and cannot answer, who will receive the result and whether findings could be relevant to relatives. Ask how an unexpected finding or uncertain result would be managed. Consent should cover the scope of testing and how you prefer to receive the report.

Genetic testing is generally planned rather than urgent. Do not wait for a panel result before seeking assessment for a new lump, unusual bleeding, persistent unexplained symptoms or a noticeable change in your health. These concerns need their own clinical evaluation.

If a result causes significant distress or creates difficult family conversations, contact the genetics service for support and interpretation. Urgent help is appropriate if anxiety becomes overwhelming or you feel at risk of harming yourself.

Consider asking why this particular panel fits your history, whether an affected relative would be more informative to test first, what each possible result could change and whether relatives would need a separate clinical appointment.
