Health, Eating, Activity, & Lifestyle (HEAL) Study
The Health, Eating, Activity, and Lifestyle Study began in 1996. It enrolled approximately 1,200 women with early stage breast cancer and has completed 2-year, 5-year, and 10-year follow-up. Follow-up has been both active (at 2 years, 5 years, and 10 years for recurrences and updates of exposure variables) and passive (yearly through the respective SEER registries for vital status and second primaries).
