On the importance of removing tumors in Mohs surgery - in light of his recent passing and in memory of sports broadcaster Avi Meller

Avi Meller 1953–2025Mohs surgery is considered today the gold‑standard technique for removing malignant skin tumors in the facial area — and not by chance. It enables complete and precise removal of cancer while preserving as much healthy tissue as possible. The story of sports broadcaster Avi Meller, who faced a recurrence of a tumor that was not fully removed and ultimately became an aggressive, life‑threatening disease, illustrates how critical the choice of the right treatment method can be — for one’s health and even for one’s life.

Mohs Surgery: Why Is It So Important, Especially on the Face?

Skin cancer is the most common cancer in the world — and particularly in Israel. Israel is a sun‑drenched country with inviting beaches and a population that includes many fair‑skinned immigrants with lifestyle habits that lead to high exposure to UV radiation. It is important to emphasize that darker‑skinned individuals are also at risk, especially because many mistakenly believe they are “protected” and cannot develop skin cancer.Many malignant lesions appear in exposed areas, especially the face: nose, eyelids, ears, lips, temples, and the hairline. These are areas where:

• The skin is thin and delicate, allowing tumors to penetrate quickly.
• There is very little room for error — every millimeter of tissue matters functionally and aesthetically.
• The risk of recurrence is higher if all cancer cells are not removed.

This is where Mohs surgery comes in — a unique surgical technique in which the tumor is removed in thin layers, and each layer is examined under a microscope in real time. Only if cancer cells are found does the surgeon continue removing additional tissue. This ensures complete tumor removal with minimal damage to healthy tissue.

What Makes Mohs Surgery the Most Precise Method?

Mohs surgery combines surgery and pathology at the same moment. Unlike standard excision, where the tumor is removed “approximately” with wide margins:

• 100% of the margins — both peripheral and deep — are examined.
• The surgeon identifies exactly where cancer cells remain and removes tissue only from that area.
• Healthy skin is maximally preserved, resulting in smaller scars and easier recovery.
• Cure rates reach 97–99% for certain tumors.

On the face, where every millimeter matters, this is not just an aesthetic issue — it is a matter of medical success and improved chances of full recovery.

Avi Meller’s Case: What Happens When a Tumor Is Not Fully Removed?

It was recently reported that sports broadcaster Avi Meller faced a recurrence of facial skin cancer after the original tumor was not completely removed. The disease returned with distant metastases and required difficult chemotherapy and radiation treatments.Cancer cells left behind can continue growing beneath the surface — sometimes months or years after surgery.When a tumor recurs:

• It tends to be more aggressive.
• It may invade deeper tissues, nerves, or blood vessels.
• A simple surgery is often no longer enough.
• Additional treatments such as radiation or chemotherapy may be required — longer, harsher, and accompanied by significant side effects.

Meller’s story is a painful reminder that skin cancer is not “small” or “simple.” Inaccurate treatment can lead to a far more complex medical journey.

Why Is Mohs Surgery Especially Important on the Face?

1. Maximum precision in a sensitive area  The face contains delicate structures — nerves, muscles, cartilage, tear ducts, eyelids, and more. Unnecessary damage can cause functional problems, not just cosmetic ones.2. Preserving a natural appearance  Mohs surgery allows optimal reconstruction with smaller scars and precise placement of incisions.3. Preventing recurrence  Complete removal the first time significantly reduces the risk of the cancer returning.4. Handling complex tumors  Recurrent tumors, tumors with unclear borders, or tumors in difficult locations are particularly suited for Mohs surgery.

Who Should Consider Mohs Surgery?

Not every skin cancer requires Mohs, but it is preferred in cases such as:

• Facial basal cell carcinoma (BCC)
• Squamous cell carcinoma (SCC)
• Recurrent tumors
• Tumors with unclear borders
• Tumors in areas where tissue preservation is crucial
• Younger patients seeking optimal cosmetic results

What Happens If Mohs Surgery Is Not Chosen?

In standard excision, the tumor is removed with relatively wide margins. The problem:

• Not all margins are examined, so cancer cells may remain.
• If the tumor returns, it may be larger, deeper, and more dangerous.
• A more extensive surgery may be needed, sometimes with additional treatments.
• Cosmetic results may be inferior.

In other words: saving time or cost initially may lead to a far more complex treatment later.

A Message to the Public: Do Not Compromise on Treatment Quality

Avi Meller’s story is not just personal — it is an important lesson for anyone facing a suspicious facial lesion. Skin cancer is common, but when treated correctly, it is usually fully curable.Choosing Mohs surgery can be the difference between:A short, focused treatment  andA long, painful, complicated medical journeyEspecially on the face, where even a small mistake can become a big problem.

In Summary

Mohs surgery is not “just another surgery.” It is the most precise method for removing malignant skin tumors from the face, offering a rare combination of:

• Microscopic accuracy
• Very high cure rates
• Preservation of appearance and function
• Prevention of recurrence

Avi Meller’s story reminds us how important it is to choose the right treatment the first time. When it comes to skin cancer, there is no room for compromise.
