Radiation therapy involves giving high doses of radiation beams directly into a tumor. The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

- damage to surrounding tissues (e.g. lung, heart), depending on how close the area of interest is located to the tumor.
- inability to kill tumor cells that cannot be seen on imaging scans and are therefore not always included on the 3D models (e.g. in near-by lymph nodes.
Can radiation cause chronic fatigue?
After radiation therapy begins, fatigue usually increases until mid-way through the course of treatments and then stays about the same until treatment ends. For many patients, fatigue improves after radiation therapy stops. However, in some patients, fatigue will last months or years after treatment ends.
