Incoming M1 interested in Gen surg

Well, i am actually interested in both Gen surg and family medicine. So before starting medical school, i wanted to work in a lab at the school i graduating from but was wondering which field would be more beneficial : Genetic, lymph, pancreatic, infectious disease, etc.. I am planning on spending at least 3 month in a lab prior starting med school. Thanks
