Omega-3 Fatty Acids in Cancer

Anti-inflammatory fatty acids reducing inflammation and supporting immune function in cancer patients.

Definition

Long-chain polyunsaturated fatty acids (EPA and DHA) with anti-inflammatory properties and emerging evidence for supporting cancer patient outcomes. These nutrients modulate immune response and reduce systemic inflammation common in cancer.

How it works

Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), possess powerful anti-inflammatory properties through multiple mechanisms. They reduce pro-inflammatory cytokine production, support immune cell membrane function, and may help preserve lean muscle mass in cancer patients experiencing cachexia. Research shows omega-3 supplementation can improve appetite, reduce fatigue, and support treatment tolerance in cancer populations. These fatty acids also promote healthy gut microbiota, which enhances immune surveillance. Unlike omega-6 polyunsaturated fats that can be pro-inflammatory, omega-3s help rebalance the inflammatory environment in cancer patients.

Role

Reduces chronic inflammation and modulates immune response while supporting cellular health and potentially slowing cancer progression.

Examples

  • Fatty fish: salmon, sardines, mackerel
  • Fish oil supplements
  • Algae-based EPA/DHA supplements
  • Flaxseeds and chia seeds (ALA form)

Recommendations

Consume fatty fish 2-3 times weekly or take 1-3g daily of combined EPA/DHA supplements during cancer treatment. Choose purified, third-party tested supplements to avoid contaminants. Maintain balance with omega-6 intake and discuss supplementation timing with your oncology team.

Key takeaway

Omega-3 fatty acids combat cancer-related inflammation and support immune function, making them a valuable nutritional strategy during cancer treatment.
