Australian scientists from Queensland University tried a new method and were able to identify cancer at an early stage in a person saliva, RIA Novosti reports.
They assure that to detect cancer in the earliest stages, until it has grown into a large tumor and has not led to complications in the form of metastasis, is a very difficult task. Therefore, experts try to come up with and create a simple test, allowing to identify forerunners of pathology.
in their opinion, a promising option is to diagnose oncology on saliva analysis. This method is safe and painless for the patient. In addition, the saliva contains many different cells and their fragments.
Oncological diseases in some cases provokes human papilloma virus (HPV). They are widely circulated in the population and infect those who are just beginning to lead sex life. Most often, an infected person is getting rid of the virus in two years, but sometimes larynx cancer, genital, head and neck cancer are developing. HPV is able to cause cancer on its own, and provoke already modified cells. However, according to experts, in both cases, its DNA is preserved in saliva.
The experiment was attended by 523 volunteers, among which 501 were already treated from cancer. All of them handed over their samples of saliva and PCR test on Papillomavirus DNA. 43.2 percent of them received a positive result. Scientists stressed that such a method of diagnosis of cancer at an early stage was sensitive, but to confirm its effectiveness it is necessary to carry out additional research.
Earlier, a candidate of medical sciences, a dermatologist Irina Svogogudeva said that improper hand washing could lead to dangerous consequences. She explained that frequent hand washing has a negative impact on the skin. Soap destroys a lipid barrier that protects the skin from damage and penetration into the organism of dangerous elements. In addition, improper hand washing contributes to the development of oncology.
