Get to the Bottom of It: Why Anal Pap Smears Matter for MSM

Hey friends — it’s Dr. Tom from Tom of P-Town Health, here to talk about something we don’t talk about enough: anal Pap smears.

Yes, you read that right. It’s not glamorous, it’s not dinner-table conversation (unless you have really fun friends), but it’s hugely important for your long-term health — especially if you’re a man who has sex with men (MSM).

Let’s break it down without blushing.


🧫 What is an Anal Pap Smear?

Just like the cervical Pap smear that’s been saving lives for decades, an anal Pap test checks for abnormal cells in the lining of the anus — changes that could be caused by human papillomavirus (HPV), the same virus linked to cervical, throat, and anal cancers.

During the test, we use a small swab (about the size of a Q-tip) to gently collect cells from the anal canal. It takes about 30 seconds. You might feel a little pressure or mild discomfort, but most people say it’s less awkward than a dentist appointment — and definitely less painful than skipping it and finding out too late that something’s wrong.


🧍‍♂️ Why MSM Should Care

Here’s the deal:

  • HPV is common — like, really common. Most sexually active adults have been exposed at some point.

  • Among MSM, especially those living with HIV, the rate of high-risk HPV (the type linked to cancer) is significantly higher.

  • That means MSM have a higher lifetime risk of anal dysplasia (precancerous cell changes) and anal cancer.

Screening helps us catch those changes early — long before they turn into something dangerous.


📋 What Are the Current Recommendations?

Screening guidelines vary a bit depending on HIV status and risk factors, but here’s the general gist:

  • HIV-positive MSM: Annual anal Pap smear starting at age 35 (some start as early as 30).

  • HIV-negative MSM: Every 2–3 years starting around age 40, depending on individual risk.

  • Anyone with a history of anal warts, HPV-related disease, or receptive anal intercourse: You’re in the group that benefits most from regular screening.

(And yes, if you’ve had the HPV vaccine — fantastic! But keep screening. The vaccine doesn’t cover every high-risk strain.)


🔬 What Happens if It’s Abnormal?

If your anal Pap shows abnormal cells (like ASC-US, LSIL, or HSIL — our alphabet soup of cell changes), don’t panic. It doesn’t mean you have cancer.

It just means your provider will likely recommend a high-resolution anoscopy (HRA) — a closer look with a magnifying scope and sometimes a small biopsy. The goal is to find and treat any precancerous areas before they progress.

In most cases, early treatment and monitoring prevent anything serious from ever developing.


💪 Why This Matters

We talk a lot about self-care and sexual health in the LGBTQ+ community — testing, PrEP, mental health — but anal cancer prevention often gets left out of the conversation.

The reality? Anal cancer rates among MSM are 20–30 times higher than in the general population.
Screening saves lives — and the process is simple, quick, and absolutely worth it.


🩺 Bonus Tip from Tom of P-Town Health

If your doctor looks puzzled when you ask about an anal Pap smear, give them a nudge in the right direction — and refer them to our textbook for clinicians,
📘 “Primary Care of Men Who Have Sex With Men: A Reference for Providers who want to provide culturally competent and comprehensive care"

And if you want to take charge of your own health journey, keep an eye out for our upcoming patient guide:

Because knowing your body — and your options — is how you stay ahead.


🏳️‍🌈 Bottom Line (pun still intended)

If you’re an MSM and haven’t had an anal Pap yet, it’s time.
It’s preventive care that’s empowering, responsible, and easy — the kind of adulting that keeps you around to enjoy many, many more Provincetown summers.

So schedule that Pap, bring your questions, and let’s normalize talking about this stuff.

Your health is sexy.
Your prevention is power.
