“Significant increases were verified in Brazilian rates between 1996 and 2006, followed by stable rates until 2010. For men, predictions indicate increasing rates both at a national level and by geographic regions, except for the South region (where a decrease is expected). In women, increasing rates are expected for the overall country and for the North, Northeast, and Central West regions, whereas decreasing rates are expected for the Southeast and South regions. At a national level, the predicted increase in deaths by colorectal cancer is 75.8% in men and 67.5% in women: 55.8% and 60.6% can be attributed to population changes and 20.0% and 7.0% because of risk increases.”

“Increasing mortality rates for colorectal cancer are expected in Brazil until the year 2025, mostly because of the aging process of the population. The results presented herein show that the disease burden will be higher in the North, Northeast, and Central West regions of the country, which also correspond with the least developed regions.”
