The blood tests that we have are not very sensitive. So, they often miss the presence of cancer in the applicant. Therefore, American engineers created a device designed to continuously work on the human body, collecting various data and diagnosing a dangerous disease in time. Any malignant tumor every minute releases more than a thousand cells into the bloodstream that can be identified by a blood test. But not every test will capture a sufficient volume of malignant cells. This leads to skipping cancer at an early stage. This problem should be solved by a diagnostic device created by specialists from the University of Michigan. The researchers created a prototype wearable gadget that can continuously collect information about the presence of cancer cells in the blood. The author of the project, Sunita Nagrat, explained that if you scan more substantial volumes of blood, you can catch a sufficient number of malignant cells, which is quite difficult to achieve as a result of one familiar blood sampling. Often in relatively late stages of the disease, blood tests show a lack of sensitivity. The new methodology, according to Nagrat, is designed to eliminate this factor. As animal testing showed, the device captured 3.5 times more cancer cells per milliliter of blood than traditional blood tests. According to co-author Daniel Hayes, this technique embodies the highest accuracy of examinations, which is so important in the detection of cancer. The sensor will detect tumors in the early stages of their formation. He will be able to identify molecules that serve as therapeutic targets for fresh cancer drugs. People will most likely begin testing the device in 3 to 5 years. In the meantime, the team increases the efficiency of blood processing. Regarding the cost, durability and autonomy of the gadget, there is no information yet.
