Multiethnic cohort studies are essential for several reasons: - Diversity in Genetics: Different ethnic groups have unique genetic profiles that may influence cancer susceptibility. - Environmental Exposures: Varied living conditions and occupational exposures can affect cancer risk differently across populations. - Lifestyle Factors: Dietary habits, physical activity, and smoking rates can vary significantly between ethnic groups, impacting cancer incidence. - Healthcare Access: Disparities in access to healthcare and quality of care can lead to differences in cancer detection, treatment, and outcomes.
