A nurse cares for a client who has a family history of colorectal cancer. The client states, "My father and my brother had colon cancer. What is the chance that I will get cancer?" How would the nurse respond?

Choice A reason: Having two first-degree relatives with colorectal cancer significantly increases an individual's lifetime risk. Clinical guidelines recommend that these high-risk individuals begin screening at an earlier age (usually age 40 or 10 years younger than the earliest diagnosis) and undergo more frequent colonoscopies to detect and remove precancerous polyps before they become malignant. Choice B reason: Preemptive surgery (such as a total colectomy) and chemotherapy are extreme measures and are generally not indicated for someone with a family history unless they have a confirmed genetic syndrome like FAP. Prophylactic chemotherapy is not a standard medical practice for cancer prevention in the absence of a current diagnosis or high-stage disease. Choice C reason: This statement is medically inaccurate and dangerous. Colorectal cancer risk does not "skip generations" in a predictable way. Furthermore, while some forms of colon cancer are autosomal dominant (like Lynch syndrome), having first-degree relatives with the disease always necessitates increased vigilance and screening rather than a false sense of security. Choice D reason: While diet is a modifiable risk factor, a "low-fat and low-fiber" diet is actually associated with an increased risk of colorectal cancer. High fiber is protective. Furthermore, for someone with a strong familial predisposition, lifestyle changes alone are insufficient; they must be coupled with rigorous clinical surveillance via colonoscopy.
