High-Resolution Anoscopy

HRA Detects and Prevents Anal Cancer

The number of people diagnosed with anal cancer is increasing each year and early detection is key. Methods for prevention and early detection include Anal Pap Smear, which can look for abnormal cells and High-Resolution Anoscopy (HRA), which can detect anal dysplasia (pre-cancerous cells) and anal cancer.

Recently, a major, national study called the Anal Cancer/HSIL Outcomes Research (ANCHOR) found that anal cancer can be prevented by identifying and removing precancerous cells using the HRA procedure.

Doylestown Health Colorectal Specialists now offer both Anal Pap and High-Resolution Anoscopy in the office setting. If a Pap comes back with abnormal cells, HRA allows our colorectal surgeons to take a closer, more precise look at the anal area. If necessary, they can perform a biopsy immediately and send the sample off to the lab for further examination. If the biopsy shows pre-cancerous cells, the area can often be treated in the office as well.

People at Risk

Individuals who are at high risk for anal cancer include those who are:

  • Infected with human papillomavirus (HPV)
  • Immunocompromised as the result of HIV (human immunodeficiency virus) or from drugs that suppress the immune system
  • Engaging in anal-receptive sexual activity or have a history of it
  • Women with abnormal cervical Pap test results
  • Patients with genital warts
