Hemorrhoid suppositories mainly have anti-inflammatory, anti-swelling, pain-relieving, blood cooling and hemostatic effects, but they are not used to control the symptoms of rectal cancer. It may have some therapeutic effect on the localized blood in stool or mild pain symptoms of rectal cancer, but the therapeutic effect is very limited. Patients with rectal cancer still use surgery as the main treatment method. Clinical guidelines believe that neoadjuvant radiotherapy and chemotherapy are routinely performed before rectal cancer surgery, and neoadjuvant radiotherapy and chemotherapy can shrink the mass or even reduce the tumor stage, which can play a good auxiliary role in the later surgical treatment, increase the cure rate of surgical resection and prolong the survival of patients.
