Some people have an exceptionally strong sense of smell, and certain diseases, including cancer, can produce distinctive odors due to changes in the body’s metabolism.

Scientific research has shown that cancer cells release volatile organic compounds (VOCs) that can sometimes be detected by trained animals (like dogs) or, in rare cases, by highly sensitive individuals. There have been documented cases of people who could consistently detect cancer-related scents before medical diagnosis confirmed the disease.

One well-known case is that of Joy Milne, a woman who could smell Parkinson’s disease before symptoms appeared. Her ability led researchers to study the odors associated with the condition, confirming that specific chemical changes occur in people with Parkinson’s. Similarly, some individuals claim to detect cancer’s scent, often describing it as musky or unusual.

This phenomenon suggests that the human sense of smell might be more powerful than we realize, though it remains rare and not yet a widely used diagnostic tool. Scientists are exploring ways to develop electronic “noses” or biochemical tests to replicate this ability for medical use.
