• Click the ‘get started’ button
• In the top left under “choose cancer site,” choose ‘colon andrectum’ from the drop-down menu

o In more options, Do not worry about ‘precision’—just leave itat 0.1 (the default); Select “rates” under table display
Please note: data updates as options are selected
Answer below:
• What is the incidence rate in 2000?
• And in 2016?
• Describe the incidence rate trend over time in the U.S. forcolorectal cancer (note the highest year)
b. Calculate the incidence rates for colorectal cancer for womenand men according to race/ethnicity (Black and White only) (0.4points).
