What happens when you have lymphoma?
Lymphoma happens when these white blood cells start behaving differently. Instead of fighting infections and dying off naturally when they get old, they begin to multiply too quickly and build up inside your lymph nodes or other parts of your body.
This causes the glands to swell, creating a lump or bump that you might feel under your skin.
