A mid-sized jet, the 757 isnât nearly the size of a 747 or 777, but thanks to a nasty aerodynamic quirk it produces an outsized wake that, according to one study, is the most powerful of any airplane.

Causes: Colorectal cancer: All kinds of cancer occur when cell division, normally a very highly regulated process, gets out of control. While environmental factors can certainly contribute to a person's risk of cancer (e.g. smoking, diet, and exercise), most cancers have a genetic basis too.
For colorectal cancer, death rates increase with age. Colon and rectum cancer is the second leading cause of cancer death in the United States. The number of deaths was 15.5 per 100,000 men and women per year based on 2008-2012 deaths.
