Anal dysplasia is a pre-cancerous condition which occurs when the mucosa lining of the anal canal undergo abnormal changes. During this condition, lesion, or visible pattern of clustered abnormal cells, appear. These cells may then progress from low-grade lesions to high-grade lesions.[1]
Symptoms include anal warts in and around the anus.[2]
Causes
Anal dysplasia is most commonly linked to human papillomavirus (HPV), a usually sexually-transmitted disaease. HPV is the most common sexually transmitted disease. Roughly 80% of people who have had one or two lifetime sex partners and 100% of people who have had five lifetime sex partners have had HPV infection, which may persist for life.
