Anal fissures are small tears or cracks on the part of the anus that opens when you pass stools— where the inside of the anus meets the outside. They are associated with pain and bleeding during bowel movements. Most will heal on their own and do not require treatment. In adults they can be caused by passing a large, hard stool, or by having frequent diarrhea. In older adults they may occur due to decreased blood flow to the area. Having too much tension in your sphincter muscle or having anal intercourse may also cause anal fissures. Anal fissures are common in those with chronic constipation or diarrhea. However, if your infant has blood in their diaper you should take them to visit a doctor.

What is anal cancer?
Anal cancer is a rare cancer that arises from the anus. The anus is comprised of the anal canal, a passage about cm or 1. Anal cancer refers to several types of cancer that can develop in this area. The most common symptoms of anal cancer include bleeding from the anus, itching around the anus, and anal pain. Anal cancer tends to spread slowly. With early treatment, in many cases, it has a relatively good prognosis. This condition tends to affect older adults between the ages of 50 and 80, and is slightly more common in women than in men. Treatment depends on the type of anal cancer and stage of diagnosis, but typically involves a combination of surgery and chemotherapy.
What are the main risks of anal sex?
Muscles anal sphincters that surround the anal canal relax to allow waste to leave your body. Anal cancer is an uncommon type of cancer that occurs in the anal canal. The anal canal is a short tube at the end of your rectum through which stool leaves your body. Most people with anal cancer are treated with a combination of chemotherapy and radiation. Though combining anal cancer treatments increases the chance of a cure, the combined treatments also increase the risk of side effects. Talk to your doctor about any signs and symptoms that bother you, especially if you have any factors that increase your risk of anal cancer. Anal cancer forms when a genetic mutation turns normal, healthy cells into abnormal cells. Healthy cells grow and multiply at a set rate, eventually dying at a set time. Abnormal cells grow and multiply out of control, and they don't die. The accumulating abnormal cells form a mass tumor.

Several STIs, once thought to be on the verge of extinction, have recently reemerged. This change is thought to be partially related to an increase in STIs of the anus and rectum. In this report, we review common anorectal STIs that are frequently referred to colorectal surgeons in the United States. Epidemiology, clinical presentation, and management are summarized, including the latest treatment recommendations. Core tip: Anorectal sexually transmitted infections constitute a group of emerging diseases not well recognized by the medical community. An understanding of recent trends in sexual behavior and the epidemiology of sexually transmitted infections is critical to identifying populations at risk.
