Breast Cancer (cont.)
Radiation therapy
Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells. Most women receive radiation therapy after breast-sparing surgery. Some women receive radiation therapy after a mastectomy. Treatment depends on the size of the tumor and other factors. The radiation destroys breast cancer cells that may remain in the area.
Some women have radiation therapy before surgery to destroy cancer cells and shrink the tumor. Doctors use this approach when the tumor is large or may be hard to remove. Some women also have chemotherapy or hormone therapy before surgery.
Doctors use two types of radiation therapy to treat breast cancer. Some women receive both types:
- External radiation: The radiation comes from a large machine outside the body. Most women go to a hospital or clinic for treatment. Treatments are usually 5 days a week for several weeks.
- Internal radiation (implant radiation): Thin plastic tubes (implants) that hold a radioactive substance are put directly in the breast. The implants stay in place for several days. A woman stays in the hospital while she has implants. Doctors remove the implants before she goes home.
Side effects depend mainly on the dose and type of radiation and the part of
your body that is treated.
It is common for the skin in the treated area to become red, dry, tender, and
itchy. Your breast may feel heavy and tight. These problems will go away over
time. Toward the end of treatment, your skin may become moist and "weepy."
Exposing this area to air as much as possible can help the skin heal.
Bras and some other types of clothing may rub your skin and cause soreness.
You may want to wear loose-fitting cotton clothes during this time. Gentle skin
care also is important. You should check with your doctor before using any
deodorants, lotions, or creams on the treated area. These effects of radiation
therapy on the skin will go away. The area gradually heals once treatment is
over. However, there may be a lasting change in the color of your skin.
You are likely to become very tired during radiation therapy, especially in
the later weeks of treatment. Resting is important, but doctors usually advise
patients to try to stay as active as they can.
Although the side effects of radiation therapy can be distressing, your
doctor can usually relieve them.
You may want to ask your doctor these questions before having radiation therapy:
- How will radiation be given?
- When will treatment start? When will it end? How often will I have treatments?
- How will I feel during treatment? Will I be able to drive myself to and from treatment?
- How will we know the treatment is working?
- What can I do to take care of myself before, during, and after treatment?
- Will treatment affect my skin?
- How will my chest look afterward?
- Are there any long-term effects?
- What is the chance that the cancer will come back in my breast?
- How often will I need checkups?
