Anoscopy is a procedure to examine the walls of the anus and part of the rectum. It is performed with a rigid tube (anoscope) that is inserted a few inches into the anal canal. Most people feel no pain during an anoscopy. The patient may feel a pressure like an urge for bowel movement, or a pinch if tissue is removed for biopsy. Read more: Is an Anoscopy Painful? Article

How to Stop Anal Itching
Anal itching is the irritation of the skin at the exit of the rectum, known as the anus, accompanied by the desire to scratch. Causes include everything from irritating foods we eat, to certain diseases, and infections. Treatment options include over-the-counter medications, using moist pads, and gentle cleaning and drying of the anus.
Hemorrhoids (piles) are swollen veins in the rectum and anus. Causes include pregnancy, obesity, diarrhea, low-fiber diet, and prolonged sitting on the toilet. Treatment varies depending upon the severity of the hemorrhoids. Some treatment options include over-the-counter creams and suppositories, stool softeners, warm sitz baths, and hemorrhoidectomies.
Blood in the Stool (Rectal Bleeding, Hematochezia)
Blood in the stool or rectal bleeding (hematochezia) refers to the passage of bright red blood from the anus. Common causes include anal fissures, hemorrhoids, diverticulitis, colitis, Crohn's disease, colon and rectum polyps, and cancer. The color of the blood in the stool may provide information about the origin of the bleeding. The color of stool with blood in it may range from black, red, maroon, green yellow, gray, or white, and may be tarry, or sticky. Treatment of blood in the stool depends on the cause.
Colon Polyps: Symptoms, Causes, Cancer Risk, Treatment, and Prevention
Colon polyps are common growths on the inner lining of the colon. Colon polyps may become cancerous. There are several different types of colon polyps, and the chance of the polyp becoming cancerous depends on the type, size, and histology. Blood in the stool or rectal bleeding are the most common symptoms of colon polyps. Treatment for colon polyps depend on the type, size, and histology.
Colon cancer (bowel cancer) is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
An anal fissure is a small tear or cut in the skin lining of the anus. Pain and/or rectal bleeding during bowel movements are common symptoms of anal fissures. Treatment includes increasing liquid intake, using stool softeners, prescription medications, and surgery.
Early Warning Signs and Stages of Colon Cancer
Colon cancer or colorectal cancer, is a type of cancer that begins in the cells lining the large intestine (colon). In the early stages of colon cancer, warning signs and symptoms usually don’t occur. Colon cancer usually does not have any signs or symptoms. As the cancer grows and expands it may begin to produce signs and symptoms, for example, diarrhea, constipation, blood in the stool, and narrow or pencil-thin stools.There are four stages of colon cancer; however, The term Stage 0 is sometimes used for a very early cancer that only affects the lining of the intestine. The other stages of colon cancer are stage 1, 2, 3, and 4.
Anal cancer, cancer located at the end of the large intestine, has symptoms that include anal or rectal bleeding, anal pain or pressure, anal discharge or itching, a change in bowel movements, and/or a lump in the anal region. Treatment for anal cancer may involve radiation, chemotherapy, or surgery and depends upon the stage of the cancer, its location, whether cancer is eradicated after the first treatment, and whether the patient has HIV.Anal cancer is usually curable when found localized. Early detection remains the key to long-term survival as it is in many forms of cancer.
Colon Cancer Prevention
Colorectal cancer is both curable and preventable if it is detected early and completely removed before the cancerous cells metastasize to other parts of the body. Colonoscopy and flexible sigmoidoscopy (along with digital rectal examination and stool occult blood testing) are both effective at preventing colo-rectal cancers and detecting early colo-rectal cancers.
