Radiation therapy uses high-energy rays or particles to destroy cancer cells. Radiation may be used for Hodgkin lymphoma (HL):
The amount of radiation given during treatment, and when and how it is given, will be different for each person. The dose and schedule for the radiation therapy are determined by:
HL is often treated with external beam radiation therapy. A machine directs radiation to the tumour and some of the surrounding tissue.
Radiation treatments are given to different areas of the body when treating HL. The radiation field is the part of the body that receives the radiation. Some of radiation fields to treat HL are:
Total nodal irradiation is the term used when radiation is given to all fields. It is basically a combination of the mantle and inverted Y fields. This approach may be used for people with widespread, advanced stage disease.
Total body irradiation is the term used when low-dose radiation is given to the entire body in preparation for a stem cell transplant.
Each person’s situation is unique, and the radiation fields may be adjusted depending on the extent of the disease.
For cancer survivors, the Canadian Cancer Society provides a unique opportunity to celebrate their courage in the fight against cancer. During hundreds of Relay For Life events across the country, thousands of survivors join together for the Survivors’ Victory Lap.
