Russian scientists develop new, more efficient way to detect cancer cells in blood


Scientists have found the parameters of the laser radiation at which melanoma cells generate ultrasound signals, according to a study published in the journal Scientific Reports. The study will analyze a large amount of blood and even detect cancer at an early stage.

Scientists at Saratov State University in Russia have developed this new, highly effective method that detects cancer cells in the blood. According to the researchers, about 90 percent of cancer deaths are linked to the formation of metastases. Let us let you know that when a tumor grows in any part of the body, it quickly makes cells. These cells enter the bloodstream. After that, these cells reach other parts of the body and form new tumors. This is called metastasis.

The primary tumor is often successfully removed with surgery, but non-metastatic cancer is curable. In such a situation, it is necessary to detect cancer cells in the patient’s blood as early as possible.

Here is how the procedure goes:

In this procedure, a blood sample is placed in a flow cytometry which passes blood cells through a laser beam one cell at a time and the response is analyzed.

This process measures blood cells and helps the doctor make the diagnosis. Artificial cancer cells have been developed which produce a sound similar to cancer cells.

Between 30 and 50 percent of cancers can now be prevented by avoiding risk factors and using evidence-based prevention strategies. Finding cancer early, along with the right treatment and care for patients who develop cancer, can help reduce the burden of cancer. Many cancers have a good chance of being cured if caught early and treated properly.

When cancer is caught early, it is more likely to respond to treatment, resulting in a greater chance of survival, less morbidity, and less expensive treatment. By detecting cancer at an early stage and avoiding delays in treatment, the lives of cancer patients can be dramatically improved.
