Anal polyp cancer

The vast majority of anal polyps are benign, and anal polyp cancer is only a rare case. In fact, all polyp diseases have such characteristics. When anal polyps are discovered, they need to be resolved as soon as possible. There are many ways to treat anal polyps. The specific method should be determined based on the patient's condition. As long as the treatment is timely, the prognosis of anal polyps is still very good.

Anal polyps refer to pedunculated round or oval tumors on the anal canal or rectal mucosa that can protrude into the intestinal cavity and move up and down. Most of the pedicle is caused by the extension of intestinal mucosa due to intestinal peristalsis or feces. Anal polyps are mostly caused by chronic irritation from feces. They are common benign tumors, but a few may become malignant. Most anal polyps are single, while multiple ones are a minority.

Anal cancer is still relatively unfamiliar to people. Because its incidence rate is lower than that of some cancers, fewer people pay attention to it. But this is a wrong practice, and the harm of anal cancer cannot be underestimated, so let us understand what anal cancer is. Cancer that occurs below the dentate line is called perianal cancer. Squamous cell carcinoma mostly occurs in the anal canal and around the anus. It arises from the squamous epithelium of the anal canal and around the anus and is often caused by long-term chronic irritation and damage from anal fistulas, hemorrhoids, surgical scars, condylomata, hidradenitis suppurativa, and latent pilary cysts.

symptom

Anal squamous cell carcinoma often causes discomfort and itching in the anal area. There is a small, slow-growing lump on the anal verge. The pain is minimal, but may be present if the anal canal or sphincter is invaded. After a long course of the disease, ulcers will form, which are locally painful and have thin secretions that are often mixed with blood. There is grayish white necrotic tissue at the bottom of the ulcer, with eversion and granular nodules around it, which is easy to scab and bleed. Inguinal lymph node enlargement, etc. Early localized lesions should be differentiated from papilloma, condyloma, thrombosed external hemorrhoids, anal fissures and granulomatous ulcers during diagnosis.
