Why don't they put you to sleep for Mohs surgery?

They don't put you to sleep for Mohs surgery because it's an outpatient procedure done under local anesthesia, keeping you awake but numb in the treated area, which avoids general anesthesia's risks, speeds recovery, and allows for precise, layered cancer removal while preserving healthy tissue. Being awake helps the surgeon map the cancer, and the minimally invasive, staged approach makes general sedation unnecessary for most patients.

Can you be awake for Mohs surgery?

You will be awake during the entire procedure, but your Mohs surgeon can give you medicine to help you relax. The surgeon will first numb the skin around the cancerous area so you cannot feel anything. Then they will remove any suspicious areas with a layer of surrounding tissue.

What is a Mohs surgery on the shin?

Mohs surgery on the lower shin involves numbing the area, removing the tumor plus a thin layer of tissue, mapping and analyzing it microscopically, taking additional thin layers if needed until clear margins are achieved, and then closing the wound.

What is the new procedure instead of Mohs surgery?

A prominent new alternative to Mohs surgery for non-melanoma skin cancers is Image-Guided Superficial Radiotherapy (IG-SRT), a non-invasive treatment using low-energy X-rays to destroy cancer cells without cutting, bleeding, or scarring, making it ideal for patients avoiding surgery or with medical conditions that complicate it, though it requires multiple sessions over weeks compared to Mohs' single-visit approach. Other established alternatives include Electrodesiccation & Curettage (ED&C), Cryosurgery, and topical Imiquimod cream. 

How long does a typical Mohs surgery take?

How long does Mohs surgery usually take? The average Mohs surgery takes about three hours. But it could take longer, depending on what we find, so I usually tell patients to plan on being here all day.

Mohs Reconstructive Surgery: What Patients Need to Know

What type of anesthesia is used for Mohs surgery?

Mohs surgery is typically performed under local, injectable anesthesia with an anesthetic medication called lidocaine. The injection of lidocaine feels like a pinch, but once the area is numb you should only feel pressure.

How quickly should basal cell carcinoma be removed?

You should have a basal cell carcinoma (BCC) removed relatively quickly, ideally within weeks of diagnosis, but the urgency depends on the tumor's characteristics; faster-growing, larger, recurrent, or high-risk types (especially on the face, ears, nose, scalp) need urgent removal, potentially within days, while slower-growing types on less critical areas might allow for a few months' wait under doctor supervision to prevent local tissue damage and ensure a better cosmetic outcome, though treatment is always preferred sooner rather than later.
 

How quickly does squamous cell carcinoma spread?

Squamous cell carcinoma (SCC) typically grows slowly and rarely spreads, but some aggressive types can grow quickly, doubling in size in weeks and potentially invading deeper tissues or spreading (metastasizing) to lymph nodes or other organs, especially if untreated, large, located on high-risk areas like the ear, or if the person is immunocompromised. Metastasis is uncommon, occurring in 3-9% of cases, but early detection and treatment are crucial to prevent progression. 

Is there something better than Mohs surgery?

While Mohs surgery is effective, it involves cutting, potential scarring, and downtime. Brachytherapy, on the other hand, offers excellent cosmetic results with no incision. It's non-invasive, has minimal side effects, and requires no recovery time.

What are the negatives of Mohs surgery?

Disadvantages of Mohs surgery include its time-consuming nature, requiring long waits between tissue layers, potential for higher cost, the inevitability of scarring, risk of minor complications like bleeding/infection, possibility of nerve damage (temporary or permanent numbness/weakness), and it's not suitable for all skin cancers, making it overkill for small, low-risk tumors. Some patients find the awake, multi-stage process under local anesthesia tedious, and the complex wounds may need further reconstruction.
 

How urgent is surgery for squamous cell carcinoma?

Treatment should happen as soon as possible after diagnosis, since more advanced SCCs of the skin are more difficult to treat and can become dangerous, spreading to local lymph nodes, distant tissues and organs.

What is the prognosis for squamous cell carcinoma in the leg?

In general, the squamous cell carcinoma survival rate is very high—when detected early, the five-year survival rate is 99 percent. Even if squamous cell carcinoma has spread to nearby lymph nodes, the cancer may be effectively treated through a combination of surgery and radiation treatment.

How serious is melanoma on the face?

Melanoma is the most invasive skin cancer with the highest risk of death. While it's a serious skin cancer, it's highly curable if caught early.

What to wear for Mohs surgery?

You may eat a light meal before coming in for surgery. Wear a loose-fitting, button-front shirt as we will have you change into a gown. Stop taking any non-prescription medications that thin the blood at least 10 days before your scheduled surgery.

Is Mohs surgery done in an operating room?

You typically go to an outpatient surgery center or doctor's office for Mohs surgery. The procedure is done in an operating room or procedure room. The room has a lab nearby. Most of the time, the procedure takes less than four hours.

Can you have Mohs surgery without a biopsy?

If the finding is clear - there is no reason to perform a biopsy and it is possible and even desirable to refer the patient straight to a Mohs surgeon who will also perform a definitive resection.

What is the new treatment for squamous cell carcinoma?

Treatment overview

In July 2021, the FDA expanded this approval to include SCC that is locally advanced and not curable by radiation or surgery. In 2024, the FDA approved cosibelimab-ipdl (UnloxcytTM) for adults with locally advanced or metastatic squamous cell carcinoma that is not curable with surgery or radiation.

Do you always get stitches with Mohs surgery?

The vast majority of patients will have stitches. Occasionally a wound may be left to heal on its own without stitches. If your Mohs surgery wound is in a place where it can heal well on its own or where scarring is not an issue, it may be left open to heal on its own.

What is the gold standard treatment for basal cell carcinoma?

Mohs surgery is the gold standard treatment for the vast majority of basal and squamous cell carcinomas, which often occur on visible areas of the body that get the most sun exposure, like the scalp, face, nose, ears, neck, hands, and arms.

How do I know if my squamous cell carcinoma has metastasized?

Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat.

Should I worry if I have squamous cell carcinoma?

Yes, you should be concerned enough to see a doctor about any suspicious skin changes, as squamous cell carcinoma (SCC) can be serious if left untreated, potentially growing deep or spreading; however, it's highly treatable and curable when caught early, with excellent survival rates, so getting it checked quickly is key. Worry less about a scary outcome and more about timely action for a scaly patch, persistent sore, or bump that doesn't heal. 

How deep do they cut for squamous cell carcinoma?

Summary. Surgical excision remains the gold standard for the management of cutaneous squamous cell cancers (SCC) and national guidelines for operative radial margins predict 95% oncological clearance with a margin of 4 mm for low-risk and 6 mm for high-risk tumours.

Does basal cell carcinoma have roots?

Superficial BCCs are common on the trunk. Infiltrative BCC – this may look more subtle, and have edges which are not clearly defined. Infiltrative BCCs have a tendency to spread a little bit more under the skin with microscopic roots.

Should I worry if I have basal cell carcinoma?

Most basal cell carcinomas grow slowly, do not spread in the bloodstream or lymph nodes and are typically not a threat to life if they are not neglected. The cancer destroys tissue adjacent to it and may get larger and more destructive with time, which is the reason to treat it.

What does stage 1 basal cell carcinoma look like?

Stage 1 basal cell carcinoma (BCC) looks like various subtle skin changes, often on sun-exposed areas, appearing as shiny pearly bumps, pinkish patches, scar-like flat areas, or sores that bleed/ooze but don't heal, typically under 2cm and localized, easily mistaken for pimples or minor wounds. Common signs include pearly bumps with visible blood vessels, pink growths with rolled edges, flat white/yellow scar-like spots, or persistent reddish, itchy patches.
