Scientists in the United States were surprised to discover that pigeons can detect and identify malignant cancer cells in the sample biopsy and mammogram scan. Even the level of detection accuracy is done pigeons, rivaling the ability of a specialist.
Research into the ability of pigeons to detect cancer, led by Professor Richard Levenson of the University of California at Davis. The researchers taught the birds to be able to recognize the difference between benign and malignant tissues in a mammogram scan and biopsy slides.
While a specialist doctor needs to learn many years to detect cancer. The researchers were surprised to find that pigeons can read the case properly after training for only two weeks.
"With the training and strengthening of food, pigeons can do what humans do. They are very adept at distinguishing between breast cancer cell benign and malignant. The level of accuracy of 85% in the first 13 to 15 "Prof Levenson said, as reported by the Mirror, November 18, 2015.
Eight pigeons take part in the experiment, pecking blue or yellow button to the picture is benign or malignant, and get a food reward for a correct answer. They act as best radiologists in detecting microscopic specks of calcifications on the mammogram, which can be an early sign of cancer.
The dove had a brain no bigger than the tip of the index finger but it has the same neural pathways that exist in humans. Previously they were also known to be able to distinguish between the letters of the alphabet and paintings by different artists.
