For educational purposes only
This guide offers educational and supportive information to help you navigate cancer care and find support — it is not medical advice, diagnosis, or treatment, and it is not a substitute for your oncology team. It does not diagnose, treat, or cure cancer, and makes no promises about outcomes; all decisions about your diagnosis and treatment should be made with your doctors. Contact your care team about new or worsening symptoms, and seek urgent care for severe problems such as a high fever during treatment, difficulty breathing, or uncontrolled bleeding. You don't have to carry this alone — if you're struggling emotionally, reach out to your team or a counsellor, and in crisis call or text 988; in an emergency, call 911.
