Status of the cancer serum donor is recognized as presence of the laevorotatory optical active molecules of (-)p density in serum while status of the recovered donor is recognized as quantitative domination of the dextrorotatory (+)p molecules in serum. These molecular information carriers (-)p and (+)p are recorded by the magneto-optical circular birefringence MOCB effect in B2 magnetic field. The laevo/dextrorotatory carriers are enantiomers in the case of (-)p = (+)p relations fulfilled for any individual cancer and the same recovered patient. The positive predictive value PPV of MOCB results is 100%.展开更多
