Eating a grilled burger gives you cancer.

(MOSTLY) FICTION! Hearing all sorts of scary stories about the dark side of firing up the barbecue? Well, don't put away your tongs just yet. While it's true that meat grilled over a high flame--particularly if it's charred--can form a number of compounds that are known carcinogens, no studies have found that an occasional grilled hot dog or hamburger is a danger. So unless you're chewing down on blackened patties morning, noon and night, there's no need to worry.
