What Challenges Do Prospective Cancer Studies Face?
Despite their importance, prospective studies face several challenges:
Long Follow-up Periods: These studies require long follow-up periods, often spanning decades, which can be resource-intensive and may result in participant attrition. High Costs: The extensive data collection and monitoring involved make these studies expensive to conduct. Confounding Variables: Many factors can influence cancer risk, making it challenging to isolate specific confounding variables.
