The Health, Eating, Activity, and Lifestyle (HEAL) Study
The Health, Eating, Activity, and Lifestyle Study began in 1996. To date, it
has enrolled approximately 1,200 women with early stage breast cancer and has
completed 2-year and 5-year follow-up. Data collection is currently in the 10-year
follow-up phase. Follow-up is 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).
