Cancer is characterized by proliferation of cells that have managed to evade central endogenous control mechanisms. There are many claims on the Internet and in publications about substances that treat cancer (for example, broccoli, grapes, ginseng, soybeans, green tea, aloe vera, and lycopene and treatments like acupuncture, vitamins, and dietary supplements). Almost every physician suggests that a balanced diet and good nutrition will help an individual combat cancer. Although some of these treatments may help reduce symptoms, there is no good evidence they can cure any cancers. Patients are strongly recommended to discuss any home remedies or alternative treatments with their cancer doctors before beginning any of these.
