Early anal canal cancer has a higher possibility of cure, while the cure rate of middle and late anal canal cancer may be smaller. 1. Early stage anal canal cancer: Early stage anal canal cancer patients, due to the small size of the tumor and the absence of proliferation and metastasis, can have the tumor cells removed through radical surgery, and the life span of most of the early stage patients will not be affected after cure. 2. Middle and late stage anal canal cancer: if the opportunity of early treatment is missed, the size of the tumor will get bigger and bigger with the prolongation of time. Most of the patients with anal canal cancer are already in the middle or late stage when they are found, losing the chance to get radical surgery, and the chance of clinical cure will be greatly reduced after the lesion spreads. For patients with anal canal cancer, clinically, it mainly manifests as itching sensation, lump in anal area, pain in anal area, local redness, swelling, heat and pain and other inflammatory changes caused by infection, and some patients may have generalized symptoms such as generalized fatigue, fever, emaciation, etc. Once detected, anal canal cancer can be found in the middle and late stages, and the chance of clinical cure is greatly reduced after the disease spreads. Once anal canal cancer is found, it is necessary to actively cooperate with doctors for treatment to improve the quality of survival. It is suggested that people should have regular physical examination and do anal fingerprinting and anoscopy routinely, which is favorable for early detection, early diagnosis and early treatment.
