Although early detection of many types of cancer has contributed to the recent increases in cancer survival rates, the survival rate for has remained almost unchanged for over 20 years. Partly this is due to their late detection. Physicians often discover only after the onset of neurological symptoms, such as loss of movement or speech, by which time the tumor has reached a considerable size. Detecting the tumor when it is still small, and starting treatment as soon as possible, should help to save lives.

One possible sign that a person has a brain tumor is the presence of tumor-related extracellular vesicles (EVs) in their urine. EVs are nano-sized vesicles involved in a variety of functions, including cell-to-cell communication. Because those found in patients have specific types of RNA and membrane proteins, they could be used to detect the presence of cancer and its progression.
