Each Triennial Survey covers a comprehensive list of topics including medical history, cancer screenings, genetic testing, and health behaviors like physical activity, sleep, diet, and smoking. Don¡¯t be surprised if you open this latest survey and think, ¡°Hey! I¡¯ve answered some of these questions before.¡±? You have.
We ask similar questions on each Follow-up Survey because we want to see if and how your health has changed over time. Responding to these surveys over time is the cornerstone of our cancer prevention cohort studies.
