The American Cancer Society said there will be approximately 13,500 cases diagnosed for people under 50 this year, but there will be more than 95,500 cases of colon cancer across all age groups and 40,000 cases of rectal cancer.
But what has experts on edge is that for people born in 1990, the risk of colon cancer is five per million people in that age group could develop the cancer. That's up from three per million for those born in 1950. The number for rectal cancer is four per million for those born in 1990. It's .9 per million for people born 40 years earlier.
