Cancer Could Be Found by One Drop of Urine

On December 16, 2017, Nagoya University which collaborated with Kyushu University, National Cancer Center Research Institute, and Osaka University announced that their development of a technology to identify cancers such as lung, pancreas, liver, bladder, prostate, etc. from 1 ml urine. Although the development of technology to diagnose cancer with a trace amount of blood has been progressed so far, this technology may be able to diagnose cancer with a less invasive method unnecessary to draw BLOOD. The results were published in the online edition of the Science Advances, the US science magazine dated December 15 (U.S. time).
The original article of that online magazine is here.
Well, I am NOT familiar with medical science at all and I do NOT know details but the outline seems to be as follows.
MicroRNAs (ribonucleic acids, learned in high school, didn’t you?) are also involved in cancer proliferation and metastasis.
Extracellular endoplasmic reticulum in urine contains microRNA.
Developed a fine structure called nanowire that captures 99% or more of the urinary extracellular endoplasmic reticulum.
They found that there are over 1000 types of microRNAs in urine ( only 200 to 300 kinds have been found so far)
This would discover that the microRNAs that specifically exist in cancer patients’ urine.
It is said that there is a possibility that the above-mentioned five cancers will be found by urinalysis.
However, it will take about ten years to put it into practical use.
My father had a colon cancer but it seems that colon cancer and gastric cancer that are more common in Japanese do NOT seem to be found by this examination. But any way, I’d like to expect this development.
