What are the Challenges of Conducting Prevention Trials?
Conducting cancer prevention trials presents several challenges, including:
Long duration: Prevention trials often require many years to yield meaningful results, as cancer development can take a long time. Large sample sizes: A large number of participants may be needed to detect differences in cancer incidence between groups. Adherence: Ensuring participants stick to the intervention protocol can be difficult, especially over long periods. Ethical considerations: Balancing the need for rigorous research with the ethical obligation to protect participants from potential harm.
