Cancer cases in people under the age of 50 have surged by 80 percent over the last three decades, fed by smoking, booze, obesity, and lack of exercise, according to a new study. The Guardian reports that deaths rose by 27 percent with more than 1 million young adults worldwide succumbing to cancer each year. Breast cancer accounted for the most cases and deaths, but the biggest spike in deaths involved kidney or ovarian cancer, the study authors said.
