What is Radiation Therapy?

Radiation therapy works to damage and kill cancer cells. It can also damage healthy cells. This can lead to you having side effects (changes) where your body is being treated.

Where Will I Be Treated On My Body?

After your CT/Planning appointment your Radiation Oncologist (cancer doctor) will create your treatment plan. You might have treatment to the:

  • Whole breast, or
  • Chest wall (post-mastectomy)

In some cases lymph nodes may also be treated. Your Radiation Oncologist or Radiation Therapist can tell you exactly where you will be getting treatment.

Common Side Effects

Radiation therapy can cause side effects in the area being treated.

Radiation side effects can:

  • Start part way through your treatment
  • Stop a few weeks after your treatment ends

If you have any side effects, or need to ask a question, talk to your Health Care Team.
