Radiation Oncology

Understanding Radiation Oncology

Radiation oncology uses a stream of high-energy particles to destroy cancer cells. The energy carried by the radiation can alter the genetic code of a cell to control how it grows and divides in the body. Other names for radiation oncology include radiation therapy, radiotherapy, X-ray therapy, cobalt therapy, brachytherapy, and irradiation.

How Radiation Therapy Is Given

Radiation oncology is given in several ways. Some patients receive more than one type.

  • External radiation treatments are painless, much like an X-ray. It is typically an outpatient procedure, in which a machine directs high-energy rays at the cancer. The treatment takes only a few minutes, but each session can last 10 to 30 minutes because of setup and placement. 
  • Internal radiation therapy uses a radioactive source that is sealed in a small container in the form of a wire, seed or pellet. The source is placed directly into or near the tumor in an implant procedure. Implants may be permanent or temporary.
  • Stereotactic radiotherapy or stereotactic radiosurgery dramatically reduces treatment time for radiation therapy on tumors anywhere in the body, and can offer hope for otherwise inoperable tumors.

Side Effects

Radiation therapy attacks reproducing cancer cells, but it can also affect normal cells. The damage to normal cells is what causes side effects. Although unpleasant, most side effects are not serious and can be controlled with medication and diet. Side effects may include:

  • Fatigue
  • Skin changes
  • Loss of appetite
  • Hair loss in the area of treatment only

Preparing for Radiation Oncology

  • Bring all your prescription drugs with you to the consultation with your radiation oncologist so the type and strength of your medication can be recorded.
  • Wear clothes that are easy to take off. Depending on the treatment area, you may need to undress.
  • Your doctor will let you know whether you can drive home from treatment or whether you will need to arrange for someone to drive you.
