How come the rate of skin cancer has increased even though we spend less time in the sun than our ancestors?

Hi guys. My dad was spouting some crap about how the increase in skin cancer is due to the sunscreen itself, stating that previous generations would toil all day in the fields with no effect and yet  only recently the rates of skin cancer is increasing even though we get less sunlight. Google brings up answers that seem junk science at best. What's your take?
