Micronutrients Linked to Skin Cancer Risk

Strategic Insights

— 2 min read

Research on the causal effects of micronutrients on skin cancer, specifically non-melanoma skin cancer (NMSC) and malignant melanoma (MM), has yielded findings that may inform prevention strategies. The study utilized Mendelian Randomization and analyzed data from 650,657 European participants, including 19,077 NMSC and 3,194 MM cases. The results showed that selenium and potassium may protect against MM, while calcium increases NMSC risk, with vitamin B6 providing protection against NMSC.

Key Takeaways:

  • Selenium and potassium were found to have a significant protective effect against malignant melanoma (MM), with a 21.2% reduction in risk (p = 0.0001, OR 0.788, 95% CI 0.703-0.883) and a 53.7% reduction in risk (p = 0.045, OR 0.463, 95% CI 0.219-0.982), respectively.
  • Calcium was found to be positively associated with non-melanoma skin cancer (NMSC) risk, indicating it may be a risk factor, with a 25.7% increase in risk (p = 0.025, OR 1.257, 95% CI 1.030-1.534).
  • Vitamin B6 showed a significant protective effect against NMSC, with a 24.9% reduction in risk (p = 0.004, OR 0.741, 95% CI 0.604-0.909).
  • The remaining 11 micronutrients showed no significant causal association with NMSC or MM (p 0.05).
  • The study analyzed data from 650,657 European participants, including 19,077 NMSC and 3,194 MM cases.
  • The research concluded that these findings enhance our understanding of micronutrients in skin cancer mechanisms and inform potential prevention strategies.
