Cancer touches everybody’s life in one way or another. But most of us know very little about how the disease works, why we treat it the way we do. The link between cancer and diet is just as mysterious as the disease itself. Much research has pointed toward certain foods and nutrients that may help prevent—or, conversely, contribute to—certain types of cancer.
Good nutrition is especially important if you have cancer because both the illness and its treatment can affect your appetite. Cancer and cancer treatments can also affect your body’s ability to tolerate certain foods and use nutrients. Cancer patients need to maintain a healthy body weight and eat nutritious foods.
