A dog’s persistent sniffing led to early lung cancer detection in a non-smoking woman, saving her life.
Colleen Ferguson, 70, of Kent, credits her German Shepherd, Inca, with saving her life after the dog repeatedly sniffed her breath, prompting her to seek medical tests.
Despite no symptoms beyond fatigue and a history of gluten intolerance, a later full-body scan revealed a golf ball-sized tumor in her left lung, diagnosed as early-stage lung cancer.
As a non-smoker with no prior health issues, Ferguson was shocked by the diagnosis, but timely surgery in June 2015 eliminated the need for further treatment.
Now retired and pursuing creative writing, she believes Inca’s instinctive behavior led to an early detection that likely improved her outcome.
The incident highlights the potential for dogs to detect health changes through scent, though the exact mechanism remains unclear.
