For external beam radiation, the physician will measure the correct angles for aiming the radiation beam at the specific area of the body and make ink marks on the patient's skin. The procedure itself is pain-free. While the radiation is being administered, the technologist will leave the room and monitor the patient on a closed-circuit television. However, patients should be able to communicate with the technologist at any time over an intercom system. Side effects of radiation therapy vary among patients.
Fatigue can be especially bothersome in the later weeks of treatment.
Patients who experience fatigue after radiation sessions should get plenty of rest and try to maintain an active lifestyle. While many patients can still work and participate in normal activities during radiation therapy, some patients find it necessary to limit their work or activities until treatment has been completed. Another side effect that may occur from pelvic radiation is vaginal stenosis, a narrowing of the vagina caused by scar tissue. Vaginal stenosis may cause pain or discomfort during sexual intercourse.
