Radiation therapy uses high energy x-rays to destroy cancer cells. When treating Hodgkin lymphoma, it is more effective when used after chemotherapy. Radiation therapy may be used to:
A radiation oncologist will customize the treatment dose for individual needs. The goal is to try and kill as much cancer while minimizing harm to healthy tissue.
There are different types of radiation therapy, but external beam radiation is used to treat Hodgkin lymphoma.
In external beam radiation therapy, radiation is produced by a machine positioned outside the body. Short bursts of x-rays are directed at the tumor site. The radiation specialist will direct the radiation beam to affect as much of the tumor as possible. External beam radiation only takes a few minutes and the total treatment time can last 5-8 weeks, depending on the total dose required. In most cases, radiation is given 5 days a week.
