Early diagnosis of tumor with electron spin resonance (ESR) : Method of electronic saturation of energy level


ESR saturation power point of the hair of healthy, lung cancer, esophageal cancer, as well as silicosis, tuberculosis and cardiovascular disease were detected. The results show that the positive rate is 1.69%, 85.42%, 90.4%, 20.00%, 27.27% and 0% respectively. There is a significant difference between lung cancer, esophageal cancer and healthy persons (P<0.001). ESR saturation power point elevates sharply after treatment of lung cancer, 71.43% of total cases ranged from 7.9 to 24.0 (mW), after treatment of esophageal cancer, 71.23% ranged from 7.9 to 19.9 (mW). All patients with cardiovascular disease were examined to be negative, i. e. , above 10.0 (mW).
