ovarian cancer:radiation therapy

Radiation therapy
Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells. A large machine directs radiation at the body.
Radiation therapy is rarely used in the initial treatment of ovarian cancer, but it may be used to relieve pain and other problems caused by the disease. The treatment is given at a hospital or clinic. Each treatment takes only a few minutes.
Side effects depend mainly on the amount of radiation given and the part of your body that is treated. Radiation therapy to your abdomen and pelvis may cause nausea, vomiting, diarrhea, or bloody stools. Also, your skin in the treated area may become red, dry, and tender. Although the side effects can be distressing, your doctor can usually treat or control them. Also, they gradually go away after treatment ends.
NCI provides a booklet called Radiation Therapy and You: A Guide to Self-Help During Cancer Treatment.

Supportive care
Ovarian cancer and its treatment can lead to other health problems. You may receive supportive care to prevent or control these problems and to improve your comfort and quality of life.
Your health care team can help you with the following problems:
Pain: Your doctor or a specialist in pain control can suggest ways to relieve or reduce pain. More information about pain control can be found in the NCI booklets Pain Control: A Guide for People with Cancer and Their Families, Get Relief from Cancer Pain, and Understanding Cancer Pain.
Swollen abdomen (from abnormal fluid buildup called ascites): The swelling can be uncomfortable. Your health care team can remove the fluid whenever it builds up.
Blocked intestine: Cancer can block the intestine. Your doctor may be able to open the blockage with surgery.
Swollen legs (from lymphedema): Swollen legs can be uncomfortable and hard to bend. You may find exercises, massages, or compression bandages helpful. Physical therapists trained to manage lymphedema can also help.
Shortness of breath: Advanced cancer can cause fluid to collect around the lungs. The fluid can make it hard to breathe. Your health care team can remove the fluid whenever it builds up.
Sadness: It is normal to feel sad after a diagnosis of a serious illness. Some people find it helpful to talk about their feelings. See the "Sources of Support" section for more information.
