Cohort Evaluation of Body Fluids Early Detection of Cancer in High-risk Individuals
LEAH is a prospective, observational, single-centre, non-randomised, open-label study of people at increased risk of cancer or malignant disease.
The main objective of LEAH is to evaluate and compare the sensitivity of different tests on body fluids to detect cancers that will occur within 3 years of inclusion in the study, in a cohort of individuals identified as being at increased risk of cancer.
