Nutrition and Cancer

Diet is important for any healthy lifestyle, but it’s especially important in the fight against cancer. Proper nutrition and cancer treatment go hand in hand. Before, during and after cancer treatment, managing nutrition is a part of recovery and future prevention.

A well-balanced diet is the fuel your body needs to maintain energy and a strong immune system throughout treatment and survivorship.
