Dogs Detect Cancer ...
Next time you visit a cancer clinic you may be greeted by a man’s best friend – A Dog!
Scientists now say that dogs can detect lung and breast cancers more effectively than state-of-the-art screening equipment.
It’s down to breath. Some Labradors and Portuguese water dogs have
been trained to identify chemical markers such as alkanes and benzene derivatives
in the exhaled breath of cancer patients.
Previous attempts to develop simple tests to identify these markers have
failed.
The researchers, who hope to repeat their findings with a larger study, believe
dogs could be used instead of mammograms and CT scans to improve diagnosis
rates.
Dr Michael McCulloch, of the Pine Street Foundation in San Anselmo, California,
and colleagues took breath samples from 55 lung cancer patients, 31 breast
cancer patients and 83 healthy volunteers.
The dogs correctly detected 99 per cent of the lung cancer samples and 88
per cent of the breath from breast cancer sufferers.
Dr McCulloch told the Integrative Cancer Therapies journal: "In parts
of the world where there isn't a large medical budget we believe that the
dogs could be used as kind of a pre-screening to help determine who would
most benefit from more expensive high-tech testing."
