During the conference of the American Association for the Advancement of Science, David Wong from the University of Los Angeles presented the basis for a new test that we could be labeled as “liquid biopsy.” From a drop of saliva it will be possible to isolate fragments of DNA tumor, one could speak of a tumor signature imprinted in body fluids, saliva and blood.
Similar assumptions were made in the past by complementary medicines such as Steiner anthroposophic medicine that has for decades used the process of the sensitive crystallization: a method that studies the crystallization of organic liquids. In other words when there is a tumor in the body the organic liquids outside the body crystallize in a different way than those in a healthy person. This is produced by an exchange of information that occurs in the body, most likely induced by the tumor DNA. Similar studies were also initiated at the University of Florence nearly 30 years ago but were interrupted for lack of funds. These new studies with cutting-edge technologies will lead in the near future to make simple tests just like pregnancy tests says Wong. However, for the moment, it has proved accurate especially for lung cancer. Saliva liquid biopsy may be the key to early detection of certain cancers, such as pancreas, for which currently there is no effective early screening. “Later,” concluded Wong, “it may be possible to have a test that can detect multiple types of cancer simultaneously.”
