When determining the focus group for a community screening program, the nurse recognizes which ethnic group as having the highest incidence of colorectal cancer?

Choice A rationale Individuals of Ashkenazi Jewish descent have a significantly higher incidence of colorectal cancer, primarily due to a specific genetic mutation, the APC I1307K variant, which is more prevalent in this population. This variant confers a moderately increased risk for developing adenomas and, subsequently, colorectal cancer. This genetic predisposition makes this group a high-priority for screening. Choice B rationale The incidence of colorectal cancer is generally lower among Asian Americans compared to other racial and ethnic groups in the United States. While lifestyle and dietary changes in immigrant populations may increase their risk over time, their genetic predisposition does not place them at the highest risk. Choice C rationale Native Americans generally have a lower incidence of colorectal cancer compared to non-Hispanic whites and African Americans. While risk factors such as obesity and diabetes are prevalent in this population, their overall incidence of colorectal cancer is not the highest among ethnic groups. Choice D rationale African Americans have a higher incidence and mortality rate from colorectal cancer compared to non-Hispanic whites. They are at increased risk due to a combination of genetic, socioeconomic, and lifestyle factors. However, the specific genetic risk factor in the Ashkenazi Jewish population results in a notably higher incidence.
