Cancer warning signs worth not ignoring
The changes in your body that deserve a doctor's visit, explained without the fear, because most turn out to be something else.

Most of these signs are not cancer
A lump, a persistent cough, or a mole that's changed is far more often something ordinary than something serious. Knowing these signs isn't about worry; it's about knowing what's worth a check rather than a wait-and-see, so that on the rare occasion it does matter, it's caught early.
Signs worth a visit, not a panic
A new lump or swelling anywhere on the body. A sore or wound that hasn't started healing after a few weeks. Unexplained weight loss. A cough or hoarseness lasting more than three weeks. A change in bowel or bladder habits that persists. Unusual bleeding, including between periods or after menopause. A mole that's changed size, shape or colour. Persistent difficulty swallowing.
Why 'it'll probably go away' isn't the right instinct here
Most causes of these symptoms are minor and resolve on their own, which is exactly why people put off checking. The small share that aren't minor are also the ones where catching it early makes the biggest difference to treatment and outcome, so the cost of checking is low and the value of ruling something out is real either way.
What actually happens when you raise one of these
A doctor examines you, decides what test or referral makes sense, sometimes nothing more than a blood test or a scan, and the great majority of these visits end with reassurance, not a diagnosis. That reassurance is worth having on record either way.
