Nutritional Support

Revised: May 2007

Why is nutrition important?

Nutrition plays an important role during your cancer treatment. Good nutrition can help you to:

  • Prevent or reverse weight loss
  • Better manage therapy related side-effects
  • Help to fight infection
  • Provide energy to speed recovery

Will cancer treatments affect my eating?

Cancer treatments can sometimes lead to side effects that can affect your ability to eat. The type of side-effects will depend on your type of cancer and it’s treatment. Because each person is unique, side effects can vary from person to person. Most side effects go away a few days or weeks after treatment ends.

If you do not experience any side effects during you treatment, it is important to eat a well-balanced diet.

How can a dietitian help me?

BC Cancer Agency dietitians help patients who are experiencing eating challenges during their cancer treatment such as:

  • Poor appetite resulting in weight loss 
  • Nausea 
  • Difficulty with chewing and swallowing
  • Diarrhea 
  • Constipation
  • Changes in the way foods taste

The dietitian can meet with you and your family/caregiver to:

  • Determine your nutritional goals 
  • Provide practical suggestions to help meet your nutritional needs
  • Provide follow up care as needed through your treatment

    Some of the cancer centres provide group nutrition counselling classes for people who have nutrition questions related to their cancer.
