How long a patient can live with rectal cancer bleeding in stool depends on the stage of rectal cancer and the patient’s recovery after surgery, radiotherapy and review, which may be 1-2 years, or more than 5 years, or a long time. The main clinical manifestation of rectal cancer is blood in the stool, as well as the possible combination of increased frequency of stool and unformed stool. If the patient’s tumor stage is relatively early, he can undergo radical tumor treatment, regular review and chemotherapy after surgery, and combined with radiotherapy when necessary, the general 5-year survival rate is still very high, that is, he can live for a long time. If the patient’s tumor is late and belongs to advanced stage, the survival time after surgery may be shorter.
