MOHS

Mohs Surgery​

Many treatments require surgical excision of skin cancer, followed by days of waiting for lab results. In contrast, Mohs surgery allows patients to leave within hours, cancer-free.

Mohs surgery is the most advanced and precise skin cancer treatment, with the highest cure rates of up to 99%! It removes tumors while preserving healthy tissue, yielding excellent cosmetic results and minimal recurrence. It’s the gold standard for basal cell and squamous cell carcinomas.

How Mohs Surgery Works

Mohs surgery is a special way to take care of skin cancer spots. In this procedure, the doctor gently takes off thin layers of skin, bit by bit, and looks at each layer carefully under a microscope to see if any cancer is still there. They keep doing this until only healthy, cancer-free skin is left behind.

1

The visible tumor and a thin layer of surrounding skin are removed.

2

The tissue is examined under a microscope to see if any cancer cells remain at any of the edges.

3

If any cancer cells remain, additional skin is removed and examined under the microscope.

4

This process continues until no more cancer cells are found at the edges.

What Our Clients Say

Derma is a gorgeous top of the line Dermatology facility that provides dermatology and skin care treatments. Dr. Rebecca De Miguel is a warm soul and immediately makes you feel welcome and cared for despite the short 10-15 minute visits. Dr.Rebecca helped me transition through hormone changes that affected my skin causing inflammation. I have had several services with Sarah and Marissa for Derma glow, peels and photo facials. The team is exceptional and know exactly what you need.

Absolutely love going to Derma. Doctor Rebecca is super thorough and I fully trust my skin in her hands. I also see Marissa there who does my lasers and other aesthetic therapies - she’s amazing, smart and gives me feedback and explains everything she’s doing so that I feel comfortable with my skincare choices.

Walking into Derma is like walking into the spa at the Ritz Carlton. It's such a stunning clinic! Dr Rebeca and all the staff are fabulous. Dr Rebeca caught a precancerous mole on my chest and removed it painlessly. She has also done Botox for me over the years, which always turns out looking subtle and natural. Sarah has given me Geneao facial while I was pregnant, which made my skin really glow. Marissa has done IPL on my face and chest twice and removed all of my sundamage. Derma team keeps you looking young and staying healthy! Everyone needs to get their moles checked yearly, so this is the place you should book. Dr Rebeca is a legend of a dermatologist in the Cayman Islands! She has helped more than half the island population with skincare, and she's the only one in the country preforming MOHS surgery. What a place ! 👏

Frequently Asked Questions

As the surgery is conducted using local anesthesia, it’s advisable to have a regular, nutritious breakfast and/or lunch on the day of the procedure. The only exception would be if you have scheduled your reconstruction with another doctor following Mohs surgery; in that case, please adhere to the specific guidance provided by the other physician’s office.

As alcohol thins the blood and therefore can promote unnecessary bleeding we recommend that you avoid consuming alcoholic beverages a minimum of 24 hours before and after your surgery.

Before your surgery, it’s important to ensure you’ve taken your daily prescription medications, especially blood pressure medications. If you usually take antibiotics before dental or other surgical procedures due to artificial joints or heart valves, kindly let us know when you arrive for your appointment, as we may administer antibiotics prior to surgery.

Patients who have been prescribed blood thinners by a physician should continue following their prescribed regimen. While stopping these medications may reduce surgical risks such as bleeding and bruising, doing so can increase the risk of more serious events like stroke, heart attacks, or blood clots. If you choose to discontinue a blood thinner on your own, please coordinate a plan for resuming the medication after your surgery is complete.

For patients on warfarin (Coumadin), it’s essential to have your INR checked one week before the surgery. If your INR level is greater than 3.0, kindly inform us. Your safety and well-being are our top priorities.

We strongly advise arranging for a companion to transport you to and from our office on the day of your surgery. This individual is welcome to stay with you during the waiting periods between procedure stages. Furthermore, if someone other than yourself is responsible for post-operative wound care, our nurse can provide them with clear instructions and a demonstration of the proper wound care procedures. Your safety and comfort are our top priorities.

Recovery times can vary depending on how much tissue is removed and your lifestyle. The time it takes for the wound to fully heal typically takes between 4 and 6 weeks; however, it may vary depending on its size. If proper post-care is applied, then issues such as infections, bleeding, and pain tend to rarely occur.
After surgery, your Mohs surgeon will inform you of what to expect and tips to follow during the recovery process. However, below are some tips that we recommend to ensure a smooth recovery process.
  • Keep your wound clean by washing your hands with warm, soapy water. Then gently wash your wound and surrounding skin with mild soap and water.
  • Apply petroleum jelly to keep your wound moist so as to avoid a scab forming. Do not use antibiotic ointment unless you see signs of infection.
  • Cover your wound with sterile bandages and replace frequently.
  • Do not go swimming or submerge your wound in a hot tub during the headline process.
