Are rectal polyps cancerous?

  Patient: My father is 75 years old, has suffered from hemorrhoids for many years, and recently underwent surgery for mixed hemorrhoids at a local hospital. During the operation the doctor cut a polyp tissue and the test result was: tubular villous adenoma with moderate atypical occurrence of glands. Please ask Director Li: Is this result cancerous? Can I review it now?  Patient: Thank you, Dr. Lee! My only concern is that I didn’t have a colonoscopy before I had hemorrhoid surgery, is there still a possibility of polyps existing in the colon and rectum? When can I have it checked? If they exist, would it be too much to check after six months? I would like to ask Dr. Li to reply in his busy schedule.  Li Xingqian, Department of Anorectology, Dongguan People’s Hospital: You can have a colonoscopy one month after hemorrhoid surgery.  Patient: Thank you, Dr. Li.  Li Xingqian, Department of Proctology, Dongguan People’s Hospital: You are welcome.
