What Are the Challenges in Studying Diet and Cancer?
Several challenges exist in studying the link between diet and cancer:
- Dietary Assessment: Accurately measuring dietary intake is challenging due to reliance on self-reported data, which can be subject to recall bias and measurement errors. - Confounding Factors: Multiple lifestyle and genetic factors can confound the relationship between diet and cancer risk. - Long Latency Period: The long latency period between dietary exposure and cancer development makes it difficult to establish causality.
