Video: What Causes Cancer?
Besides the obvious causes, such as tobacco use, too much sun, and excessive drinking, what causes cancer in an otherwise healthy person? The American Cancer Society is looking in the Twin Cities for healthy volunteers between the ages of 30-65 willing to commit to long-term participation in the third of an ongoing series of studies aimed at preventing cancer. Preliminary steps to participate are minimal -- a waist measurement and a blood sample starts the research off. Find out why people are signing up.
