Rectal ulcer bleeding for one year may not necessarily become cancerous, but it has the risk of becoming cancerous, so we must pay attention to it and actively carry out treatment, including drug treatment and surgical treatment. If the rectal ulcer has been bleeding for one year, it means that the course of the disease is long and the effect of treatment is not good. The risk of cancer will increase if the course of the disease is long, but it is not necessarily cancerous, so the patient should undergo a comprehensive examination in time in order to clarify the condition and give reasonable treatment. Bleeding rectal ulcer can be treated with glucocorticoids, commonly used drugs are sodium succinate hydrocortisone, dexamethasone, etc.; some immunosuppressant can also be used, such as azathioprine, mercaptopurine, etc.; when complicated by rectal carcinoma, surgical treatment should be taken in time, so as to avoid the delay of the best time for treatment. Patients with bleeding rectal ulcer should follow the doctor’s prescription during the treatment, actively cooperate with the doctor’s treatment, and undergo regular checkups in order to promote the recovery of the condition.
