The Athens Medical Association is warning the Greek public about machines and practices in so-called alternative medicine that promise painless, instant diagnoses and "magic" cures.
The association said diagnosis and treatment require recognized training, clinical experience, certified tools and evidence-based protocols. It urged particular caution with devices that claim to diagnose many illnesses, assess the whole body or even read a person's mental state through a single "scan."
It also warned against treatments for serious or chronic disease that rely on unproven methods or promise "miraculous" results.
It said patients should be wary of anyone who tells them to stop their prescribed care.
The association asked people to consult their own doctor before acting, and to ask about the scientific evidence, risks and options.
It also urged them to report questionable practices so authorities can check their legality and safety.
"Exploiting the anxiety, vulnerability or hope of a person facing a health problem is a particularly serious matter," it said. Early reporting protects patients and public health, it added.
The warning follows the death of singer Giorgos Mazonakis on Sept. 9 after a procedure at an unlicensed Athens clinic.
Two doctors are in pretrial detention.
Health Minister Adonis Georgiadis has since announced tougher oversight, including a digital platform that has flagged 231 cases for review and stricter rules on medical advertising.
