The tumor that grows on hemorrhoids is called an anal papilloma, also known as anal papillary hypertrophy, which is one of the common benign tumors around the anus. It occurs mainly due to long-term inflammatory stimulation or pain leading to benign inflammatory hyperplasia of the tissues around the anus. Anal papillomas are small at first and basically asymptomatic. Long-term inflammatory stimulation will make it grow gradually, and when it grows up, it will detach from the anus. At this time, it is recommended that the patient should directly excise it, and the hemorrhoids at the base of it can be excised as well, so as to solve the problem completely. Anal papilloma is a benign tumor, will not be cancerous, clinical cases of cancer have not been seen, small anal papilloma can not be dealt with. Small anal papillomas can be left untreated. If they prolapse from the anus and affect the life, they can be treated with surgery, which is simple and effective.
