Article Writing Homework Help

I will pay for the following article Cancer-sniffing dogs. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. What drew my interest to this specific but experimental area of cancer detection was the promising statistic from the April’s issue of Harper’s Index about five cancer-sniffing dogs at a California clinic. The dogs were reportedly highly accurate in detecting lung and breast cancers with 99% and 88% accurate diagnosis respectively. Statistically, this made the canines even more effective than a standard mammogram in diagnosing breast cancer, with its accuracy rate of 85%. Reports of dogs being able to sniff out cancer have been doing the rounds since the past five years, though this method has only recently emerged as a possibly better alternative to the traditional cancer diagnostic tools.

But is it really possible to sniff out cancer or could it be just another absurd idea as some people claim? It is now an established fact in the scientific community that cancer patients emit traces of biochemical substances such as alkanes and benzene derivatives in their breath, especially those with lung and breast cancer (Kleiner).These are metabolic waste products of the cancer cells and are different from those given off by the normal cells in the body.

Previous studies have pointed out that dogs, on their part, can detect chemicals in concentrations as small as a few parts per trillion (Kleiner). According to James Walker, director of the Sensory Research Institute at Florida State University in Tallahassee (Lovgren), the area devoted to the sense of smell in a dog brain is proportionally much larger than that of humans.

, though it is not known what exactly makes their sense of smell 10, 000 to 100, 000 times superior to that of humans.
