What is the quickest and easiest way to gat cancer?

Hard to say, but...: From a population standpoint, some ways people get cancer are by smoking stuff, being obese, and getting too many sunburns. So, the plan should be never to smoke anything, as it is toxic and unnatural to be habitually inhaling burning material. Next, eat only what is needed to keep a normal weight, and remember to get lots of exercise. Finally, sunshine is a good thing, but in small daily doses.
