Radiation therapy is used in the treatment of cancer to kill cancerous cells. The American Cancer Society notes that radiation was discovered more than 100 years ago. Since then advances in medicine have been made, allowing for a better understanding of the effects of radiation treatment on the body. Radiation damages cancer cells in order to stop the cells from dividing and growing. Radiation therapy may also damage healthy tissue, causing unwanted side effects.
Side Effects of Radiation
The goal of radiation is to treat only the cells in or around the affected area. Radiation may be used to shrink cancer cells before surgery or can be used to prevent a recurrence after surgery. Healthy tissues in the body may respond differently to radiation. Side effects often depend on where on the body radiation treatment is being given. Side effects can occur quickly or may takes weeks or months after treatment to arise. Common side effects include fatigue and skin changes on the affected area. Mouth and throat problems may occur if treatment is given above the neck. Memory loss, nausea, decreased libido, hair loss, vomiting or diarrhea, and changes in fertility may occur.
Vitamins
A multivitamin containing trace minerals such as zinc, magnesium and calcium may be beneficial to guarantee nutritional needs are being met, the University of Maryland Medical Center notes. Omega-3 fatty acids from fish oil or flax oil supplements may help reduce inflammation caused by radiation. A probiotic supplement, which helps increase healthy intestinal flora, may help reduce diarrhea associated with radiation treatment.
Herbal Supplements
Panax ginseng may help reduce fatigue caused by radiation treatment. Holy basil and milk thistle tea or extracts may help protect the body from damage caused by radiation. Calendula and aloe vera, topical herbal creams applied to the skin, may help reduce skin irritation, pain and redness at the treatment site. Chamomile or ginger tea may help reduce radiation-related nausea and stomach distress. Herbal remedies may interfere with other medications, and additional scientific research is needed to validate these claims. Do not take herbal supplements without speaking to a medical professional.
Considerations
Taking supplemental antioxidant vitamins such as vitamins C, D, E and A may interfere with the radiation's ability to kill cancer cells. An oncologist may suggest discontinuing the use of these vitamins during treatment. Eating a well-balanced diet including fruits, vegetables, nuts, beans and whole grains can help ensure that vitamin and nutrient needs are being met during treatment. Patients should always speak with a medical professional before taking any vitamin supplements during radiation treatment.
