Anal intraepithelial neoplasia (AIN) is a little-known but very important condition

It represents precancerous changes of the anal canal cells, most often associated with human papillomavirus (HPV) infection, especially types 16 and 18. 📊 According to studies, among high-risk groups AIN occurs in up to 25–30% of cases, and the likelihood of progression to cancer is many times higher than in the general population. 👥 High-risk groups include: • people living with HIV, • men who have sex with men, • patients after organ transplantation, • individuals with severe immunodeficiency. ⚠️ The main danger is that AIN can remain asymptomatic for a long time. Sometimes itching, discharge, or discomfort may occur, but these signs are nonspecific. 🩺 Modern clinical guidelines emphasize that early detection and regular follow-up with a colorectal specialist can stop progression and prevent anal cancer. 👉 Advice for patients: do not postpone examination if you notice any symptoms. 👉 Advice for doctors: remember the importance of screening in high-risk groups. Early diagnosis of AIN means a real chance to prevent anal cancer.
