Figure 2 Incidence rate of colorectal cancer and mucinous colorectal cancer and the rate of early-onset colorectal cancer and early-onset colorectal cancer with a mucinous histology. ^aThe annual percent change (APC) is significantly different from zero at alpha = 0.05. CRC: Colorectal cancer; Early-onset CRC: CRC cases in patients younger than 50 years.
