A nurse is assisting with teaching a community health presentation about reducing the risk of cancer. Which of the following instructions should the nurse include?

A. Schedule a baseline colonoscopy at 55 years of age: Current cancer-prevention guidelines recommend starting routine colon cancer screening at age 45 rather than 55. Delaying screening increases the risk of missing early polyps or malignancies. Earlier screening allows timely removal of precancerous lesions. B. Consume a low-fiber diet: Low-fiber intake slows bowel transit and increases exposure of the colon lining to potential carcinogens. High-fiber diets support healthy digestion and help reduce colorectal cancer risk. Lowering fiber contradicts evidence-based cancer-prevention recommendations. C. Obtain immunizations for hepatitis B: Hepatitis B vaccination reduces the likelihood of chronic HBV infection, which is a major risk factor for liver cancer. Preventing viral hepatitis helps protect liver cells from long-term inflammation and cellular damage. Immunization is a key cancer-prevention strategy in community health. D. Use sunscreen with a sun protection factor (SPF) less than 8: Sunscreen with SPF below 8 provides minimal protection from UV radiation, increasing the risk of skin cancers. Effective prevention requires using SPF 15–30 or higher, applied consistently. Low-SPF products fail to block harmful ultraviolet exposure.
