Many people take
vitamins and supplements while they are being treated for cancer; some take them to prevent cancer. Here are tips to help you shop wisely.
Supplements to Fight Cancer
Cancer patients are increasingly turning to supplements to strengthen their immune systems and ease nausea from chemotherapy.
Vitamin D is one of the most studied supplements for cancer prevention and treatment right now.
Vitamin A, vitamin C, vitamin E , and beta-carotene contain antioxidants once thought to help prevent cancer. However, more recent studies show that high levels of these, in supplement form, may increase cases of gastrointestinal cancers, such as stomach, colon, and esophageal, in some populations. However, eating foods that contain these vitamins reduces the risk of many kinds of cancer.
Dietary fiber helps ease constipation, which may be caused by some cancer medicines.
Folic acid helps reduce the toxicity of the cancer drug methotrexate. However, in men, high levels of folic acid may raise the risk of prostate cancer.
Iron supplementscan improve the fatigue caused by iron-deficiency anemia, which can result from chemotherapy and radiation.
