Early Warning Signs of Cancer

Symptoms you should never ignore. Most of these signs can have non-cancer causes — but getting checked early is always the right choice.

Important Note

Having these symptoms does not mean you have cancer. Many can be caused by other conditions. However, if any symptom persists for more than 2–3 weeks, please consult a doctor. Don't ignore it — don't panic. Just get checked.
