The main 'red flag' signs and symptoms of lymphoma cancer have been named by doctors, and they can show up before a person is even diagnosed with the condition.
Non-Hodgkin lymphoma, which is diagnosed in around 13,000 people in the UK every year, affects the lymphatic system which is a collection of glands and vessels situated throughout the body.
A third of cases occur in those over the age of 75 and people are more likely to be diagnosed as they get older, but it can show up in any age group.
