- the specific trajectory for cancer cells is that when the cancer cells move, the microscopic vibration is 0.5 to 0.5 to less than that of normal blood cells. It was estimated to be due to the occurrence at a specific frequency of 1.5 Hz. It was estimated that this is because the surface of cancer cells is much rougher than that of normal cells.
