General signs worth discussing with a doctor
The signs below are general and very often caused by something harmless. The point is not to worry, but to know that persistent, unexplained changes are worth a conversation with a doctor.
Changes some people are advised to get checked
- A new lump or swelling anywhere on the body.
- Unexplained weight loss, tiredness, or persistent pain.
- Changes in a mole's size, shape or colour.
- Unusual bleeding, or a sore that does not heal.
- A persistent cough, hoarseness, or difficulty swallowing.
- A lasting change in bowel or bladder habits.
Important: these signs are common and usually not cancer. Only a doctor can assess them. If you notice a persistent or unexplained change, book an appointment — finding the cause early is always sensible, whatever it turns out to be.

Common questions
I have one of these signs — do I have cancer?
Almost certainly these signs have a harmless cause, but only a doctor can tell. Please book an appointment rather than relying on any website.
