Lymphoma is a cancer of the lymphatic system. The lymphatic system helps your immune system protect your body against infection and disease.
There are lots of different types of Lymphoma, but as a rule they’re split into two categories:
What body part does it affect?
- Lymphoma cells usually start to grow in lymph nodes, which are sometimes also called lymph glands.
- These are found all over the body.
- This means that Lymphoma can occur pretty much anywhere, but the most common place is in the lymph nodes in the neck. The next most common places are the lymph glands under the arms, in the chest, or around the groin.
- Lymphoma cells can spread through the lymphatic system to lymph nodes in other parts of the body. They can also enter the bloodstream, which can carry them to other organs.
What’s the difference?
It’s only possible to tell the difference between Hodgkin’s and non-Hodgkin’s lymphomas when the cells are looked at under a microscope.
