Dogs Smell Cancer – level 2
Military dogs which used to protect soldiers now are trained for something else. Italian scientists are training them to sniff out prostate cancer in patients’ urine.
Dogs’ noses are very powerful, as they have up to 300 million sensors compared to only six million in humans. One dog was even able to identify the disease in a patient before the medical team.
However, you will not see dogs in hospitals any time soon. The team wants to develop an electronic tool which would work like the dog’s sense of smell.
Difficult words: sniff out (find by smell), urine (the scientific word for ‘pee’), develop (create, make).
You can watch the original video in the Level 3 section.
