American and British experts have claimed to have discovered the easiest method for early diagnosis of lung cancer through joint efforts.
At present, some blood tests including CT scan are done to diagnose lung cancer, however, such tests delay the diagnosis of the disease.
But now experts claim to have discovered a new method, which will make it possible to diagnose the disease in its early stages.
According to the research published in the medical journal ‘Plus’, experts from other countries, including America, Britain and India, conducted breath tests on 414 people to discover a new method.
Most of them, 156 people, had cancer but had not been treated.
The study included 113 people, who were selected from families with a family history of lung cancer and who also smoked.
While the 80 volunteers in the study were perfectly healthy, non-smokers, 65 had benign nodules in their lungs.
Experts conducted breath tests on all the volunteers and noted the presence of special chemicals in their breath through a breathalyzer.
According to experts, people whose breath contained VOS chemicals (Volatile Organic Compounds) found in the human body and blood were diagnosed with cancer. Research has shown that the presence of 7 types of chemicals in human breath in a computerized breath testing machine means a diagnosis of cancer.
That is, if the machine detects the presence of seven types of chemicals in the breath of any person, they will be diagnosed with lung cancer.
On the other hand, experts who have been researching lung cancer for a long time believe that the seven chemicals in question can be released from human breath for various other reasons.
According to experts, all chemicals released from the human body or blood are exhaled after accumulating in the lungs, so different chemicals released from the breath at the same time usually do not mean cancer.
Experts also stressed the need for more research on newly discovered methods of lung cancer diagnosis.
