Epidemiology of Colorectal Cancer
In the United States (US), colorectal cancer is the third most common cancer and also the third leading cause of cancer-specific deaths (Centers for Disease Control and Prevention (CDC), 2020). The estimated new cases and deaths resulting from colorectal cancer in 2020 alone are 147, 950, and 53,200 respectively, according to the National Cancer Institute (2020). Colorectal cancer accounts for about 8% of the total new cases of cancer among men and women. It also accounts for about the same percentage of all cancer-specific deaths. However, the prevalence of colorectal cancer in the US has been on a gradual decline from 1992-2017, except for three consecutive years in 1996, 1997, and 1998 where it rose slightly and then started declining again (National Cancer Institute, 2020). The incidence rates among older adults have dropped to 3% per year. This decline has been attributed to increased screening, a decrease in colorectal cancer risk, and changes in the occurrence of colorectal cancer risk factors (Siegel, et al., 2017). Additionally, five-year survival rates have improved. The National Cancer Institute ( 2020) indicates that the five-year survival rate( from 2010-2016) was at 64.6%. While this decline is true for middle and older adults, the situation is different for younger adults. Siegel, et al. (2017) indicates that the incidence of colorectal cancer has, surprisingly, gone up among young adults. Also, despite the decline in prevalence rates, many men and women are still at the risk of developing colorectal cancer. It is estimated that about 4.2% of American men and women will, at some point in their life, be diagnosed with colorectal cancer (National Cancer Institute, 2020). The main risk factors for colorectal cancer are obesity, alcohol consumption, and tobacco smoking (Marley & Nan, 2016). Also, race, age, and certain genes predispose an individual to colorectal cancer.
