Cancer covers a large group of diseases in which some of the body's cells begin to grow and divide abnormally. There are over 200 different types, and outcomes vary hugely depending on the type and how early it's caught — which is why awareness of warning signs and taking up national screening invitations matters so much.
Common general warning signs worth getting checked by a GP include an unexplained lump, unexplained weight loss, a change in bowel or bladder habits that doesn't go away, unusual bleeding, a mole that changes shape or colour, or a cough or hoarseness lasting more than three weeks. Having one of these doesn't mean you have cancer, but it's always worth getting checked rather than waiting.
If you're invited for NHS cancer screening — for breast, cervical or bowel cancer, for example — it's well worth attending, as screening can catch problems before symptoms even appear.
