Advanced HPV, dysplasia, and anal cancer screening in Seattle, Washington
Anal Cancer Screening and Prevention
Anal HPV is common, and precancerous changes often cause no symptoms. Dr. Kratz provides anal cancer screening, high-resolution anoscopy, biopsy, treatment of anal HSIL, and ongoing surveillance, all within one specialized program. Treatment of anal HSIL has been shown to significantly reduce progression to anal cancer in high-risk patients.


Most people carry HPV without ever knowing it.
Anal HPV and precancerous changes often cause no pain, bleeding, or other warning signs. That's why screening is based primarily on risk, not symptoms. In people at increased risk, screening can identify abnormal cells before they progress to cancer.
What We Screen and Treat
Four parts of one program, one surgeon overseeing all of it.
Anal Warts
Diagnosis and removal of anal warts caused by low-risk HPV, using minimally invasive techniques like chemical treatment, electrocautery, or excision.
HPV and Abnormal Cells
Evaluation and treatment of high-risk HPV and the precancerous cell changes it can cause, including anal intraepithelial neoplasia (AIN).
Anal Cancer Screening
A dedicated screening program for patients at higher risk of anal cancer, following the protocol established by the ANCHOR Study.
High-Resolution Anoscopy
The magnified, in-office exam used to find and treat abnormal tissue before it becomes cancer.
Evidence-based, not experimental
The ANCHOR Study, a landmark national trial, proved that treating high-grade anal dysplasia significantly reduces the risk of developing anal cancer. That finding changed how anal cancer prevention is practiced, and it's the standard this program follows.
Screening, biopsy, and treatment happen in one office, without routing patients through a separate specialist for each step.
