It takes about three months to six months for a cancer patient to go from intermediate to advanced stages without any treatment. If active treatment is available, the intermediate stage of the disease can be completely controlled at any time, so that the patient cannot reach the advanced stage for several years or even ten years. Therefore, early detection, diagnosis and treatment of cancer is the key to cure and longevity. Most of the cancer can be completely cured if the cancer can be actively treated with surgery in the early stage, complete removal of the cancer and radical surgical treatment. By the middle stage, if patients can cooperate with surgical treatment, chemotherapy, radiotherapy, immunotherapy, targeted drug therapy, biotherapy and so on, to control the growth, development and spread of the tumor, it can also maximize the time and prolong the patient’s development to advanced cancer and life-threatening development, which will greatly prolong the life span.
