While screening has many benefits, it also has potential harms, including:
False Positives: Incorrectly identifying someone as having the disease, leading to unnecessary stress and invasive follow-up tests. False Negatives: Failing to identify someone with the disease, providing false reassurance. Overdiagnosis: Detecting conditions that would not have caused symptoms or harm during the individual’s lifetime, leading to unnecessary treatment. Psychological Impact: Anxiety and distress caused by the screening process and results.
