What should you explain when discussing a cancer screening test with a patient who fears false positives and anxiety?

• A. Explain only the recommended age for screening.
• B. Emphasize personal benefit without discussing risks.
• C. Explain sensitivity/specificity, predictive values, false positives/negatives, benefits and harms, personalized risk, decision support, and provide resources.
• D. Avoid discussing potential harms.

Answer: (C)

Risk communication and shared decision making guide how you discuss a cancer screening test with a patient who fears false positives. Explain how the test performs in terms of accuracy—sensitivity (how well it detects disease when it is present) and specificity (how well it says someone without disease is negative). Then translate those numbers into predictive values to show what a positive or negative result means for this person, noting that positive predictive value depends on their own risk and how common the disease is in the population. This helps the patient understand that a positive result isn’t automatically a diagnosis and frames the likelihood in real-life terms. Then balance what the test can offer with its potential downsides: early detection and potentially better outcomes, but also the possibility of anxiety from a false positive, unnecessary follow-up tests, and risks of overdiagnosis or false reassurance from a false negative. Personalize the discussion by addressing the patient’s specific risk factors and preferences, and offer decision aids or resources to support informed choices. By presenting a clear picture of benefits, harms, and their own risk, you empower the patient to decide in line with their values and reduce anxiety through transparency and support.
