Colon Cancer Clinical Trial
DAILY: Vitamin D, Aspirin, ExercIse, Low Saturated Fat Foods StudY in Colorectal Cancer Patients With Minimal Residual Disease
To learn if lifestyle changes (such as diet and exercise) combined with daily aspirin and vitamin D can affect the likelihood of advanced colorectal cancer coming back (recurring)

To evaluate the dynamics of ctDNA allele fractions after 3 months of optimal lifestyle interventions and every 3 months thereafter up to 12 months
To estimate the recurrence rate at 1 year in subjects who complete 3 months of optimal lifestyle interventions
