Computed tomography (CT), which can find lung tumors, is regularly used to screen people at a high risk of lung cancer, such as heavy smokers. However, because it also detects benign nodules in the lungs, this test has a very high incidence of false positives.
Researchers have created a urine test to diagnose lung cancer early to look for proteins related to the disease. This noninvasive test may help find more tumors in the early stages of the illness and decrease the number of false positives.
Since lung cancer patients with their tumors discovered before they spread to other parts of the body have at least six times better five-year survival rates, early detection is crucial. In the area of cancer diagnostics and therapeutics, there is a renewed understanding of the significance of early cancer detection and prevention. New tools enabling us to detect cancer early on and take action are desperately needed.
The new test, which is based on nanoparticles that can be injected or inhaled, was discovered by researchers to identify tumors as tiny as 2.8 cubic millimeters in mice.
Researchers have been working on nanoparticles interacting with proteases to identify cancer for several years. These enzymes break down the extracellular matrix’s proteins, allowing tumor cells to flee from their initial locations.
