In Russia, more than 15 thousand people die from this disease per year. Moreover, the vast majority of patients could survive if the disease were detected in a timely manner, and treatment was prescribed at an early stage
In 2015, events aimed at raising public awareness about cancer and early detection of head and neck cancer were held in 27 cities of Russia.

DNA level diagnostics come to the rescue. The results of the analysis can be found already 3-4 hours after treatment. For the invention of the polymerase chain reaction (PCR), which is based on the identification of the species of any living organism, the American scientist Carrie Mullys was awarded the Nobel Prize.
In the 70s of the twentieth century, enzymes were discovered that break down DNA at specific points. Researchers have the opportunity to “cut” DNA into shorter and more stable fragments.
After this, a new discovery followed: scientists “taught” DNA to copy itself and build to such sizes that it is easy to identify. In fact, this made it possible to identify any object of interest by the selected DNA fragment: here is the DNA of the common cold pathogen, this is staphylococcus, this is the herpes virus.
