One of the most common complaints during radiation treatment is a loss of energy or fatigue. You may get tired easily because your body is using energy to fight the cancer and to rebuild injured cells.
Try to rest as much as you can and plan your activities at levels that are comfortable for you. You may want to try new, quieter activities such as handicrafts, isometrics or reading.
If you feel tired when you wake up or are not sleeping well at night, tell your radiation oncologist or nurse. If you feel you need medications for sleep, please ask your radiation oncologist.
