Japanese scientists say they have developed a method that allows them to diagnose cancer in its early stages in just three minutes using only a drop of blood.

"The technology tests for the presence of a malign tumor using just one drop of blood and allows identifying stomach, colon and pancreatic cancer in early stages in just three minutes. This technology does not exist anywhere else in the world," Russia's RIA Novosti news agency quoted Katsuyuki Hasegawa, a researcher at the Mytech company, as saying on Wednesday.

In this method, the patient’s blood is placed on a special metal plate, and is put under ultraviolet rays. If the patient has cancer, the blood begins to glow, whereas a healthy person’s blood does not glow.

"This is an absolutely new world achievement. This method is simple and it can be used at any hospital even starting from tomorrow," said Hasegawa.

Researchers from Mytech and specialists from the Showa University Koto Toyosu Hospital in Japan’s capital, Tokyo, worked together to invent the new technology.

The scientists say they still need to create a database of images that correspond to various kinds of cancer to help doctors easily diagnose which type of malign tumor a patient has.

Clinical tests of the new technology are estimated to begin in one year.
