Knowing how your body normally looks and feels can help you notice any early changes that could be caused by cancer.
Always see your doctor if you have symptoms that are ongoing, unexplained or unusual for you.
If you have a symptom that lasts for more than three weeks, see your doctor. This might be a cough that doesn’t go away, a change in bowel habits, a mouth ulcer that doesn’t heal, or feeling bloated most days.
This means a symptom that doesn’t have an obvious cause, for example having a lump or bleeding without any injury.
Symptoms that are unusual for you
This means a change in your body that is not normal for you. It could be a change in a cough you’ve had for a long time, a change to a mole, or a change in the skin on your breast.
