High Resolution Anoscopy
High resolution anoscopy (HRA) is a specialized procedure used to detect abnormal cells, precancerous lesions, and early anal cancer. It is particularly recommended for patients at higher risk, including those with a history of HPV, anal warts, or immunocompromised conditions.
Our colorectal specialists provide expert high-resolution anoscopy, using advanced imaging technology to identify and manage anal health issues with precision and care.

What Does High Resolution Anoscopy Diagnose or Treat?
High resolution anoscopy helps:
- Detect precancerous anal lesions
- Identify anal cancer early
- Monitor high-risk patients
- Guide biopsies for suspicious tissue
- Assess response to prior treatments
Who Should Consider HRA?
- Patients with a history of anal HPV infection
- Those with anal warts or prior anal dysplasia
- Immunocompromised patients (e.g., HIV-positive)
- Individuals with prior anal cancer or high-risk lesions
Symptoms and Warning Signs
- Anal bleeding or spotting
- Anal pain or discomfort
- Itching around the anus
- Persistent anal warts
- Changes in bowel habits
Routine screening is essential, as many abnormal cells do not cause noticeable symptoms.
How to Prepare for High Resolution Anoscopy
Preparation is simple and patient-friendly:
- Avoid anal intercourse for 24–48 hours prior
- Do not use topical creams or ointments on the anal area before the procedure
- Empty your bowels beforehand if possible
- Bring a list of medications and relevant medical history
Our team provides clear instructions to ensure the procedure is as comfortable as possible.
Before the Procedure
- Arrive 15–30 minutes early for check-in
- Bring ID, insurance information, and any prior test results
- Discuss questions or concerns with your provider
- The procedure is typically performed in-office with local anesthesia
During the Procedure
During HRA:
- A high-resolution anoscope is inserted into the anal canal
- The area is illuminated and magnified to identify abnormal tissue
- Suspicious areas may be biopsied for further analysis
The procedure usually takes 15–30 minutes. Patients may experience mild pressure or discomfort but typically tolerate it well.
After the Procedure
Recovery from HRA is minimal. You may experience:
- Mild soreness or cramping
- Minor bleeding if a biopsy was performed
- Temporary sensitivity in the anal area
Contact your doctor immediately if you experience:
- Heavy bleeding
- Severe pain
- Fever or signs of infection
Follow-up appointments are scheduled based on findings and risk level.

Frequently Asked Questions
What is high resolution anoscopy used for?
It detects abnormal cells, precancerous lesions, and early anal cancer, especially in high-risk patients.
Is the procedure painful?
Most patients experience minimal discomfort. Local anesthesia helps reduce sensitivity during the procedure.
How long does it take to recover?
Recovery is usually immediate, with only mild soreness or minor bleeding if a biopsy is performed.
How often should high resolution anoscopy be done?
Frequency depends on your risk factors, prior findings, and provider recommendations.
Can it prevent anal cancer?
While it does not prevent cancer, early detection significantly improves treatment success and outcomes.
