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.
