Medical disclaimer

Updated October 2, 2026

General education

Cancer Authority is an independent educational website. The articles, summaries, and checklists provide general information about cancer. They do not diagnose a condition, determine screening eligibility, select treatment, or replace care from a qualified healthcare professional.

Your medical decisions

Symptoms, screening recommendations, tests, and treatment choices depend on your circumstances. Discuss questions with your physician or oncology team. Do not start, stop, or change medicines, treatment, or screening based only on this website. Do not disregard professional medical advice or delay seeking it because of something you read here.

Review and currency

Research and guidelines can change. A publication date or content update does not mean an article was independently reviewed by a medical professional. We state the clinical review status on each guide. Linked sources may contain newer information or details beyond the scope of our summary.

Urgent concerns and contact

If you believe you have a medical emergency, contact emergency services immediately. Our website contact form is not monitored as an emergency service and cannot provide medical advice. For website errors and corrections, use Contact & corrections.

External services

Links and advertisements do not create a clinician-patient relationship with Cancer Authority or imply endorsement of a treatment, healthcare provider, attorney, or product. Seek advice from an appropriately qualified professional about medical or legal matters.
