Nutrition is an integral, and entirely individualized approach to cancer treatment. The food you eat affects your metabolism, health, physical function and immune response. Cancer itself, as well as its treatments, can affect your appetite, your nutrient status and the ability to maintain a healthy weight. To help you stay stronger and feel better before, during, and after your cancer treatment, nutritional counselors will provide education and guidance on nutritional therapies helping you to choose foods and needed supplements you are able to tolerate to nourish your body.
