Radiation therapy uses high-energy particles or waves to destroy or damage cancer cells. It is one of the most common treatments for cancer, either by itself or along with other forms of treatment. Our clinicians at Portneuf Cancer Center can offer the most targeted, tissue-sparing radiation therapy available.
Potential Side Effects
Fatigue is one of the most common side effects experienced during cancer treatment. It is important to manage fatigue as it can contribute to feelings of depression, lack of appetite, or increased pain.
Will I lose my hair? This is a common question amongst patients considering cancer treatment. While some patients see this as a minor side effect, others consider it very daunting. Most cancer treatments, including chemotherapy and radiation therapy, damage rapidly dividing cancer cells, but can also damage rapidly dividing healthy cells. Hair follicles happen to be one such normal rapidly dividing group of cells in our bodies.
Pain is one of the most common and feared symptoms of cancer or its treatment. If not adequately managed, pain can have a tremendous impact on your quality of life. It is important to remember that you should always notify your oncologist if you have pain or if it is increasing. Pain is usually your body’s way of telling you that something is wrong, so do not ignore it or assume that it is a necessary part of your treatment.
One of the most common side effects of radiation therapy can be skin changes. These occur because radiation has to pass through your skin in order to treat the area of cancer. Sometimes your skin is the target for radiation therapy. Most skin changes are manageable and temporary.
Nausea and Vomiting
Nausea can be a very debilitating side effect if you receive radiation to your stomach or upper abdomen. In some cases, you can experience nausea if you are receiving treatment to your brain. In either instance, be sure to alert the radiation oncology staff if you become nauseous during your treatment course.
Oral Side Effects
If you receive radiation therapy to your head or neck region, you may experience oral side effects. One of the most common oral side effects is dry mouth. Radiation can reduce the functioning of some of the salivary glands around your mouth and can thus reduce saliva. Not only can this be uncomfortable, it can lead to loss of appetite in the short-term, and possibly increased dental problems in the long-term.
Diarrhea can be a common side effect of radiation therapy directed to the abdomen or pelvis. It is important to control diarrhea so that you do not develop dehydration, rectal pain, or rectal bleeding.
For patients who receive radiation therapy to the pelvis, changes in urination can occur. Often this does not happen until the third or fourth week during treatment, but if radiation irritates the bladder, a patient can experience pain with urination, frequency, urgency, incontinence, or rarely, bleeding.
Sexual and Reproductive Side Effects
Women receiving radiation therapy to the pelvis may have vaginal side effects. Dryness, itching, and redness are common and manageable. Be sure to let your oncologist know of any of these changes. Depending upon the dose and target of the radiation, you may experience temporary, if not permanent, reduction in ovarian function, which can contribute to vaginal changes. Some women may experience hot flashes as their hormone functioning declines. Often these symptoms do improve after radiation therapy.
Men receiving radiation therapy may experience erectile dysfunction. Ejaculation can also be more painful and slightly bloody. Be sure to talk with your oncologist regarding continuing sexual activity during your treatment if you are being treated to the pelvis.
