Why have illnesses without established treatments attracted sellers of false cures?

Illnesses without established treatments attract sellers of false cures because they target individuals experiencing significant stress, pain, or sorrow who are desperate for relief. In the absence of proven medical solutions, these vulnerable individuals often crave a "miracle" and become susceptible to the persuasive personalities and exaggerated claims of charlatans.1

Quacks specifically exploit conditions that are particularly feared—such as cancer—or those characterized by frequent remissions and recurrences, like arthritis or mental disorders. By promising secret formulas or methods unknown to mainstream medicine, these sellers capitalize on a lack of public information and the human tendency to seek hope when facing insurmountable health difficulties. It is ethically imperative to recognize that such practices are fraudulent, as they prioritize financial gain over patient well-being and often delay or prevent individuals from seeking legitimate, evidence-based care.1
