Mohs Surgery – Simple Facts and Helpful Tips

If you’ve heard the term "Mohs surgery" and wonder what it really means, you’re in the right place. It’s a precise skin‑cancer removal method that saves healthy tissue while getting every cancer cell out. In plain English, a dermatologist removes thin layers of skin, looks at them under a microscope right then, and repeats until no cancer is left. That real‑time check is why Mohs has such high cure rates.

How the Procedure Works

The day of the surgery you’ll get a local anesthetic, so you stay awake but feel no pain. The doctor starts with a visible tumor and removes a thin slice, called a layer. That slice goes to a lab right next to the surgery room, where it’s stained and examined. If cancer cells show up at the edge, the doctor maps the area, removes another layer exactly where needed, and checks again. This repeats until the margins are clean. Because the doctor only takes what’s necessary, the wound is usually smaller and heals faster.

Most Mohs surgeries take 2‑4 hours, depending on tumor size and location. Common sites include the face, ears, hands, and feet—anywhere where preserving skin matters most. After the final clear margin, the doctor will close the wound. Closure options range from simple stitches to skin grafts, based on the size and depth of the defect.

Recovery and After‑Care

Recovery is typically quick. You’ll get instructions on cleaning the area, changing dressings, and watching for signs of infection—redness that spreads, increasing pain, or pus. Most people can return to normal activities in a few days, though heavy exercise should wait a week or two. If stitches are used, they’re often removed within 5‑10 days; some doctors use dissolvable sutures that disappear on their own.

Sun protection is a must after Mohs. Apply broad‑spectrum SPF 30+ daily, wear hats, and avoid peak sun hours for at least a month. Regular follow‑up visits let the dermatologist monitor the scar and ensure the cancer stays gone. Remember, even though Mohs has a cure rate over 95%, new skin cancers can develop, so keep an eye on any new or changing spots.

Feeling nervous? Talk to your doctor about pain control, what the scar might look like, and any concerns you have about the procedure. Knowing the steps ahead of time reduces anxiety and helps you focus on a smooth recovery.
