Abstract

Abstract: One of the most powerful tools in fighting cancer is early detection, as it has been strongly linked to greater chances of cancer survival. However, traditional cancer screening tests can cost hundreds if not thousands of dollars and are therefore not an affordable option for many marginalized populations. From a public health perspective, it is vital to research the use of inexpensive cancer detection so that low-resourced patients have greater access to affordable cancer screening. Numerous studies dating from the early 2000s to recent years have shown extensive evidence that the exceptional olfactory system of canines allows them to detect certain odors through exhaled breath condensate that are known to be biomarkers of a variety of cancers. In addition to providing a cheaper alternative to conventional cancer screening tests, the use of cancer sniffing dogs has other benefits, including great reliability and accuracy. There are a few major types of cancer for which the 'cancer dog test' proved to be remarkably effective, particularly colorectal, ovarian, and lung cancers. The test is non-invasive unlike most previous detection methods, meaning that it is also a safer option for individuals seeking cancer screening. Although the use of cancer sniffing dogs does have certain limitations and scope for error, it would provide a more affordable and accessible option for cancer screening, making it especially beneficial to low-resourced populations.
