Cancer Survival Rate
The proportion of individuals who survive a cancer diagnosis for a defined period, used as an indicator of treatment efficacy.
TL;DR
No supplement improves cancer survival. Some (vitamin D sufficiency, exercise nutrition) support treatment tolerance; others (high-dose antioxidants) may interfere with therapy. Oncology team oversight is essential.
Why It Matters
Cancer survival is determined by stage, tumor biology, and treatment. Observational data link vitamin D sufficiency and physical activity to better outcomes in colorectal and breast cancer, but supplementation trials have not established survival benefit. High-dose antioxidants (vitamin E, beta-carotene) showed harm signals in trials. Any supplement during active treatment must be cleared with the oncology team due to interaction risks.
How to Measure
No self-testing for survival endpoints — follow oncology surveillance protocols.
Biomarkers
Optimization Protocol
Priority: complete prescribed treatment, maintain nutrition and muscle mass (protein 1.2–1.5 g/kg/day), stay physically active as tolerated. Correct vitamin D to sufficiency if deficient. Avoid high-dose antioxidants during chemotherapy/radiation unless approved by oncology.
Lifestyle Levers
- •Complete prescribed treatment
- •Physical activity as tolerated
- •Adequate protein intake
- •Smoking cessation
- •Sleep and psychosocial support
