’Rapid increase’ in colorectal cancers among young Canadians, study finds
Canadian doctors have observed a “rapid increase” in the number of patients under age 50 with colorectal cancers and they can’t explain why.
A new study, led by doctors from the University of Toronto, looked at Canadian Cancer Registry data from 1997 to 2010 and found that incidences of colorectal cancer rose by:
- 0.8 per cent per year for people in their 40s,
- 2.4 per cent per year for people in their 30s, and
- 6.7 per cent per year for those between ages 15 and 29.
