If an elderly person has intestinal cancer, it is usually necessary to roughly determine how long the patient can live based on the results of pathological staging. If it is early stage bowel cancer, the survival time is usually longer, with 5-year survival rate above 90%; if it is advanced stage bowel cancer, the survival time is shorter, usually around 1 year; if it is progressive stage bowel cancer, the 5-year survival rate may be around 50%, so the patient may survive for 5 years or less than 5 years, such as 2 or 3 years after surgery, etc. It is generally recommended to improve relevant examinations, such as colonoscopy, abdominopelvic enhancement CT or MRI, etc., after the elderly have intestinal cancer, and if it can be surgically removed, it can be surgically removed as much as possible, and when the pathological results come out after surgery, it can be decided whether the next step is treatment, such as radiotherapy or chemotherapy, etc.
