Targeted population is cancer-free 18-60 year old men and women. Volunteer selection will rely upon a short health questionnaire. About 20 mL blood will be collected from volunteers up to 20 different timepoints. The Procedure involves minimal risk of harm (eg discomfort, bruising) to the volunteer.
