Li, who is in her 40s, suffers from abdominal pain, constipation and diarrhea repeatedly and alternately. A few days ago she came to the Second Affiliated Hospital of Zhejiang University for checkup, and as a result, Dr. Pan Wensheng from the Department of Gastroenterology used a microscope placed on the front of the colonoscope and found a 1mm cancerous lesion in her body. After surgery, Ms. Li’s disease was completely eliminated. According to the doctor, this kind of treatment, which is only carried out at the stage of tiny cancer nests, makes the cure rate of patients greatly improved. Pan Wensheng has been studying early tumor lesions for a long time, and judging by the structural changes on the surface of the tumor, he can not only find 1–2mm tumor lesions, but also determine whether it is malignant or not. After years of research, early cancer hit the potion to remove, and surgery after removal of five years of survival rate of the same efficacy. Pan Wensheng predicted that in the future, when the new technology is popularized by the society, the detection rate of early-stage bowel cancer will be significantly increased, and the five-year survival rate of bowel cancer will also be significantly increased. According to the current mid-late stage cancer surgery after chemotherapy, the average cost of 10-15 million yuan, and the patient’s physical and mental pain. Early diagnosis and treatment only requires thousands of dollars, and the treatment is less traumatic and quicker recovery, which is very favorable to the patients, their families and the society.
