The first symptom of a non-Hodgkin's lymphoma is usually a painless swelling in the neck, armpits or groin
Excessive sweating or fever, especially at night
Persistent itch all over the body
Loss of appetite, weight loss and tiredness
Children may develop a cough or breathlessness. Children may also complain of abdominal pain or you may notice a lump in your child's abdomen
If you or your child have any of the above symptoms you must have them checked by your doctor - but remember - they are common to many conditions other than non-Hodgkin's lymphomas and most people with these symptoms will not have a lymphoma.
