Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for severe difficulty breathing, sudden chest pain, coughing up blood, fainting, new confusion, signs of a stroke, or bleeding that will not stop.
These are emergencies whether or not they are related to cancer.
Arrange a prompt, routine medical assessment for a new breast or underarm lump, nipple discharge, skin dimpling, a change in breast shape, or another persistent breast change.
These symptoms are not usually an emergency but should not be ignored.
After diagnosis or treatment, contact your cancer team promptly about a new lump, persistent unexplained bone pain, an ongoing cough, worsening swelling, unexpected weight loss, or new symptoms that do not settle.
These symptoms have many possible causes and do not necessarily mean the cancer has returned.
During treatment, seek same-day medical advice for fever or chills, increasing redness or drainage around a wound, repeated vomiting, inability to keep fluids down, or rapidly worsening pain.
Cancer treatments can reduce the body’s ability to fight infection.
