The sensor for the diagnosis of prostate cancer (lat. Prostate Carcinoma) by urine was developed by scientists from the University of Liverpool and the University of the West of England. Prostate cancer is one of the most common oncological diseases among men. The success of its treatment depends heavily on the stage at which it was diagnosed. And this is the main problem because men do not like to see a doctor until the disease crosses the line when it becomes very important for life. Unfortunately, then it may be too late. The development of simple methods for diagnosing cancer will greatly help to solve this problem. The main aim of scientists is to create a test that avoids procedure of detecting cancer in a non-invasive way by smelling the disease in men’s urine.
