Discharge Instructions for Brachytherapy

You had a procedure called brachytherapy, an internal radiation treatment for cancer. A tube (called a catheter) was placed in or near your tumor during surgery. Your doctor delivered a radioactive seed to your tumor through this tube. The tube was removed after you completed therapy. You are not radioactive during your therapy. You will not expose others to radiation. This sheet gives general guidelines for taking care of yourself after you go home.


  • Plan for periods of rest throughout the day. You may feel tired from your treatment.

  • Ask your doctor what activities you can and can’t do. This will depend on the size and location of your tumor and any surgeries that you’ve had.

  • If you are on bed rest, do exercises to keep your blood flowing. Turn frequently in the bed. Move your feet up and down and side to side for a few minutes at a time.

  • Do the coughing and deep breathing exercises you learned in the hospital. Do them several times a day.

Other Home Care

  • Eat a normal healthy diet, unless your doctor tells you otherwise.

  • Take all medications exactly as directed.

  • If you have a dressing, care for it according to your doctor’s directions.

  • Don’t be alarmed by redness and hair loss in the treated area. This is a common side effect.

  • Don’t scratch the treated area.

  • Don’t use skin lotions or powders unless recommended by your doctor.

  • Take care of the skin around the area where your catheter was inserted:

    • Wash the area with mild soap and lukewarm water and gently pat it dry.

    • Protect the affected area from extreme heat or cold, such as hot showers, hot water bottles, heating pads, or ice packs.

    • Avoid clothing that causes friction or rubbing on the skin.

  • Tell your doctor at your follow-up visit if you have any of the following:

    • Trouble eating your usual diet.

    • Red, swollen, or tender areas of skin.

    • Peeling of the skin that leaves the treated area sore and moist.
