Nutrition after cancer treatment
Eating for recovery and long-term health.
What is going on
There is no single survivorship diet. General patterns rich in vegetables, fruit, whole grains, and legumes are most consistently described.
Weight change in either direction after treatment is common and worth discussing rather than hiding.
What tends to help
- A pattern rather than a rulebook
- Discussing supplements openly
- Protein with each meal during recovery
Questions worth asking
- Would seeing a registered dietitian be reasonable?
- Do any of my medicines interact with supplements I take?
Who usually owns this
- Registered dietitian
- Primary care
Contact a clinician promptly
- Unintentional weight loss, trouble swallowing, or persistent vomiting
This page cannot tell you whether your cancer has returned, and it does not adjust any medicine. Anything sudden or severe belongs with emergency services.
