Cancer on the Night Shift

Hi everyone!
I know this doesn't have anything to do with the link between food and cancer, but its an interesting article about how cancer may be more prevalent in night shift workers. Maybe the residents of the Harlem community are working more night shifts than another community so the incidence for colon cancer or breast cancer is higher.
