A nurse is teaching a class at a community center to a group of young adults, adult, and older adult clients regarding regular screening recommendations for cancer prevention. Which of the following information should the nurse include?

Rationale: A. This is too early for routine screening. Mammograms are typically recommended to begin at age 40–45, depending on individual risk factors. Women at high risk (e.g., strong family history or BRCA mutation) may begin earlier, but for average-risk individuals, age 30 is not the standard recommendation. B. Routine colorectal cancer screening for average-risk adults begins at age 45, not 40. Earlier screening may be advised for clients with a family history of colorectal cancer or inflammatory bowel disease, but this is not the general guideline. C. Current guidelines (e.g., American Cancer Society) suggest that clinical breast exams are optional for women at average risk and are no longer routinely recommended due to limited evidence of benefit. Self-awareness and routine mammography are more strongly emphasized. D. The fecal occult blood test (FOBT) or fecal immunochemical test (FIT) is a noninvasive screening tool for colorectal cancer. It should be done annually, beginning at age 45 for average-risk adults, and helps detect hidden blood in stool, which may indicate polyps or early cancer.
