A few centimeters of the tumor is early, middle and late

The pathological stage of a tumor is not determined by the size of the tumor. Clinically, malignant tumors are normally divided into early, middle and late stages, but this is not directly related to the normal size of the tumor. It is determined according to the degree of development of the tumor disease. If the patient is a carcinoma in situ or invasive cancer before metastasis occurs, it is normally classified as early stage. If lymphatic metastasis has occurred, or invasion of surrounding organs has occurred, it can be classified as intermediate stage. If distant metastasis has occurred, this indicates that the disease has entered an advanced stage, and the normal after recovery is worse, and the patient's survival time is also shorter.
