Which example raises concerns about privacy and confidentiality?

The example that raises concerns about privacy and confidentiality is the results of genetic testing for cancer markers in a healthy person. This scenario involves sensitive personal health information that is unique to an individual. Genetic test results can reveal predispositions to certain diseases, which can affect not only the individual but also inform family members about potential hereditary risks. Therefore, the handling and sharing of such data necessitate strict confidentiality measures to protect the individual’s privacy.

In contrast, reports of drug side effects are typically aggregated and do not identify individual patients, making them less of a privacy concern. A family history of reaction to a specific drug, while personal, does not reveal intimate details about an individual's current health status or genetic makeup. Similarly, prescriptions for common medications are generally part of standard medical practice and do not involve the same level of personal genetic information that requires heightened privacy protections.
