Many different types of lymphoma have shown to be extremely sensitive to radiation therapy; as a result, significantly lower doses are required on areas of the body that are smaller. This change in approach has only occurred recently, but is helping to boost efficacy while decreasing side effects.
Radiation oncologists are capable of utilizing modern technology, if available at the hospital or clinic, to reduce long-term side effects and fight against risk of damage to healthy cells. One specific method is called intensity-modulated radiation therapy (IMRT), and it is able to utilize high-tech computer programs in order to best offer radiation, directly targeting cancer cells from different angles without significantly impacting healthy ones. This forms an image that offers real-time data regarding the activity and movement of the disease, specifically illuminating where its presence is within the body.
There is also a method called Total Skin Electron Beam radiation, which has been proven to be very effective. However, very few centers offer it at the moment.
