Cancer and diet Studies have shown that cancer is more common in people with certain poor dietary habits, and there is no data to support that the use of any vitamins or supplements can reduce the risk of cancer, and in fact some supplements may increase the risk of cancer. There is also no diet that can slow, reverse or cure cancer, but some dietary treatments make cancer patients feel better. Acupuncture Acupuncture cannot cure cancer, but some evidence suggests that they can help reduce the symptoms and side effects of the disease and its treatment. Herbs against cancer There is no conclusive evidence to prove the effectiveness of herbs against cancer, but the use of certain herbs can help with some of the uncomfortable symptoms caused by cancer. Patients who have used herbs for treatment should always choose a regulated public hospital for this purpose and should clarify with your current consulting physician, as some of these herbs may interfere with your current treatment method. Homeopathy and cancer Homeopathic preparations can reduce nausea, fatigue and anxiety associated with cancer and its treatment, but should not be used as a substitute for existing conventional treatments. Social Support and Cancer Having the support of friends and family can help you cope with the depression, fear and anxiety associated with cancer. Studies have shown that men with limited social contact have shorter survival times, while women with good social support survive cancer for longer.
