Radiotherapy uses high-energy rays to destroy cancer cells, while doing as little harm as possible to normal cells. It only treats the area of the body that the beams are aimed at.
Radiotherapy is usually given daily from Monday to Friday, with a rest at the weekend. The length of your treatment will depend on the type and stage of the lymphoma. But it is normally no more than 3 weeks.
We have more information about having radiotherapy. This includes how radiotherapy is planned and possible side effects
Radiotherapy may be given after chemotherapy to:
- treat classical Hodgkin lymphoma
- treat lymphoma that remains in a group of lymph nodes
- reduce the risk of HL coming back.
Radiotherapy may also be given after surgery as the main treatment for a type of HL called NLPHL.
It may also be given if HL comes back in a group of lymph nodes.
