Cancer treatments can produce a variety of eating-related complications that can affect nutrition. Many of the side effects disappear after a cancer treatment ends. However, some patients continue to experience difficulties after therapy has concluded. Eating well can help cancer patients regain strength and rebuild tissue. It can also foster feelings of general well-being. Therefore, patients with problems are encouraged to address their eating difficulties with their physician, nurse or dietitian. If the eating problem is due to psychological factors, such as depression, the patient may benefit from medication or mental health counseling.
