Now sputum examination can identify throat cancer: Mouth and throat cancer caused by HPV virus will now be identified by sputum examination. This new trial can save thousands of lives every year. A recent research has revealed this. According to scientists at Duke University in North Carolina, this test of spit can detect the disease with 80 percent accuracy.
Now sputum examination can identify throat cancer
Process of investigation is cheap
Doctors say that this test is capable of detecting cancer early and it can help patients fight their battle against cancer. In order to use this test in hospitals around the world, more clinical trials are needed. However, researchers are hopeful that this investigation is fully capable of identifying the disease. This process is inexpensive and can give results in just 10 minutes.
Mouth and throat cancer is increasing rapidly in Western countries. The number of patients with the disease has doubled in the UK in a decade. This disease is caused by human papilloma virus. The virus penetrates from one body to another during sexual intercourse and promotes infection. Other risk factors include excessive alcohol consumption and prolonged smoking.
Researcher Professor Tony Jun Hyung said that 1,15,000 such cases of cancer occur every year worldwide. He said that due to increasing infection of HPV virus among the youth, cases of this cancer are increasing rapidly. This cancer occurs in the oropharynx. It is situated near the tongue and tonsils behind the throat. Early detection of this cancer increases the chances of this rescue by 50 to 90 percent. However, this cancer is not recognized before the advanced stage. These are difficult to see in routine checkups.
In the new investigation, a chip separates microscopic particles called exosomes present in the spit. These particles are produced in the body when cancer develops. Exosomes are known to exchange molecules between cancer and various cells. In the new investigation, the DNA of the tumor is discovered by isolating this exosome. It also identifies the HPV-16 virus present in saliva, which causes cancer in the larynx. This investigation takes five minutes.
