    High Resolution Anoscopy

    for Prevention of Anal Cancer

    High resolution anoscopy (HRA) is an outpatient procedure that allows for examination of abnormal cells in the anus using a high definition colposcope. It helps identify diseases that can affect the perianal skin and anal areas, including anal precancerous changes caused by Human Papillomavirus (HPV). It is specially designed to look for lesions that are not detected by a colonoscopy.

    doctor patient talk
    The following groups of people are particularly susceptible to persistent HPV infection and should consider HRA for screening:

    • those who have had an organ transplant;
    • those who require long term steroid use or other medicine that suppresses the immune function
    • HIV patients
    • those who have a medical condition that affects the immune system.
    • women with previous history of cervical, vaginal or vulvar cancer or precancerous changes
    • men who have sex with men
    The procedure is performed at our Outpatient Department and requires no special preparation. It takes around 30 - 60 minutes only and you can resume normal activities except strenuous activities for a few days. If a high grade abnormality is detected, you will be offered treatment to reduce the chance of the lesion turning into cancer.
