Some cancers are classified as rare because they occur less frequently in the general population. In some cases, these tumours are linked to inherited changes in genes that increase cancer risk. Identifying an underlying genetic cause can help explain why a rare tumour has occurred and guide future care.
Rare tumour hereditary cancer panels are designed to assess genes associated with a range of less common cancer syndromes. These panels may support earlier surveillance, tailored management, and informed decision‑making for individuals and their families, particularly where cancer occurs at a young age or there is a family history of related conditions.
Testing may be considered for individuals or families with a history of rare or uncommon tumours, including those associated with:
Not all rare tumours are inherited, but genetic testing can be helpful when clinical features or family history raise concern for a hereditary condition.
Testing may be considered for individuals with a rare tumour diagnosis, especially if it occurred at a young age, if there are multiple or unusual tumour types in the family, or if a known hereditary syndrome is suspected.
No. Many rare tumours occur without an inherited genetic change. A normal result can still be reassuring and help guide appropriate ongoing care.
Testing usually requires a blood sample. The sample is analysed in a specialised laboratory to look for inherited changes in genes associated with cancer risk.
If an inherited gene change is identified, this information may be useful for family members, who may choose to seek genetic advice or testing to better understand their own risk.
