Radiation damage to cells in the body can happen after a person receives radiation therapy to treat cancer. It can also happen if a person is exposed to radiation through x-ray imaging, nuclear power, or fallout from nuclear weapons. If severe enough, radiation damage may cause cancer, birth defects, heart disease, and other serious health problems. Doctors try to protect people undergoing radiation therapy for cancer by using low doses, being precise about targeting the radiation, and minimizing side effects. Usually side effects go away after the treatment stops.
Signs and Symptoms
Radiation damage can cause a number of symptoms. These are common side effects when a person undergoes radiation treatment for cancer:
Radiation sickness or radiation emergency happens after exposure to a large amount of radiation. Acute radiation sickness occurs within 24 hours of exposure. Chronic radiation syndrome is a range of symptoms occurring over a period of time. These symptoms can happen immediately or months or years after exposure to radiation:
What Causes It?
Damage happens when radiation interacts with oxygen, causing certain molecules to form in the body. These molecules can damage or break strands of DNA in cells. The cells may die.
Who is Most At Risk?
People who have been exposed to radiation, and who also have the following conditions or characteristics are at risk for developing radiation damage:
What to Expect at Your Provider's Office
If you have symptoms of radiation damage, you should see your doctor right away. A physical exam, lab tests, pathology tests, and imaging procedures such as barium radiography or colonoscopy may be performed.
If you are receiving radiation treatment for cancer, your doctor will try to prevent or reduce the risk of radiation damage and radiation side effects. Your doctor may administer low-dose radiation, use chemicals to protect from radiation, and use special shields for other parts of your body. Some medications, supplements, vitamins, and minerals may help reduce side effects.
The treatment plan depends on the type of radiation damage. If a person is exposed to a high amount of radiation, they will need to be decontaminated and may need transfusions of fluids, red blood cells, white blood cells, and platelets. If you have radiation side effects from cancer treatment, your doctor may be able to give you medications and ointments to reduce them.
Your doctor may prescribe a variety of medications, depending on your symptoms. To treat side effects from radiation during cancer treatment, your doctor may prescribe antinausea medications, oral rinses for your mouth, and hydrocortisone cream for your skin. There is one drug, amifostine, that may be used to protect against radiation damage.
Surgical and Other Procedures
Surgery may be needed to stop more cell damage, or to graft healthy tissue onto a damaged area. Preliminary studies suggest that stem cell therapy may help reduce radiation induced salivary gland damage and improve quality of life for people.
Complementary and Alternative Therapies
A comprehensive treatment plan for managing the effects of radiation may include a range of complementary and alternative therapies (CAM). If you are receiving radiation therapy, taking prescription medications or have pre-existing medical complications, talk to your health care provider before using CAM therapies.
If you are undergoing radiation therapy for cancer treatment, ask your oncologist before taking any supplement or vitamin. While some supplements may help, others may be harmful or interfere with certain cancer treatments. Make sure all your doctors know about any treatments you are considering.
Nutrition and Supplements
These nutritional tips may help reduce side effects from radiation therapy:
Certain nutritional supplements and botanical medicines may be helpful in terms of managing the side effects of radiation therapy while others may interfere with the effectiveness of certain cancer treatments. Work with your doctor to determine which supplements are best for you. Preliminary studies suggest that vitamin E supplements may protect organs from radiation damage.
Another supplement you may want to consider is a probiotic supplement containing 5 to 10 billion CFUs (colony forming units) a day. Probiotics may help reduce diarrhea in people receiving radiation therapy for cancer in the pelvis or abdomen. Some acidophilus products require refrigeration. Check labels carefully. Probiotics may not be appropriate for severely immunocompromised person. Speak with your doctor.
Herbs are generally available as standardized, dried extracts (pills, capsules, or tablets), teas, or tinctures/liquid extracts (alcohol extraction, unless otherwise noted). Mix liquid extracts with your favorite beverage. Dose for teas is 1 to 2 heaping tsp. per cup of water, steeped for 10 to 15 minutes (roots need longer).
If you are undergoing radiation therapy for cancer, ask your oncologist before taking any herb.
Radium bromatum is specific for radiation poisoning, especially followed by arthritic complaints. Acute dose is 3 to 5 pellets of 12X to 30C every 1 to 4 hours until symptoms are relieved.
The prognosis depends on the level of radiation exposure, how quickly the person can be treated, and how detailed the follow up is. Long-term complications may include cancer, liver failure, infertility, and thickening and scarring of lung, liver, and kidney tissue.
