Part 2/9:
The Unlikely Hypothesis: Can Smell Diagnose Disease?
Joy's conviction caught Kuna's attention. It was not typical for a medical professional to suggest a change in odor as a symptom of disease, especially when many in the medical community tend to dismiss such observations. However, inspired by Joy's certainty, Kuna took a step further. He consulted his colleague, analytical chemist Pita Baran, about the plausibility of humans being able to detect the scent of diseases. While skeptical, Baran acknowledged that dogs are already trained to sniff out certain cancers, leaving a curious question: If dogs can smell cancer, might humans detect Parkinson's through scent as well?
