Expressed consent refers to clear and unambiguous consent given by an individual voluntarily and with full understanding. In healthcare, it involves obtaining consent from patients before performing procedures or treatments, ensuring they are fully informed about the risks and benefits involved. In data privacy, expressed consent is required for collecting and processing personal data, empowering individuals to control their own information and make informed decisions about its use. Legal organizations, medical professionals, and data controllers play crucial roles in ensuring that expressed consent is respected and enforced.
