Skin Cancer

At Rendon Center for Dermatology and Aesthetic Medicine, your health is always our top priority. Skin cancer is treated with the utmost care, compassion, and, of course, expert skill. We believe that skin cancer detection and treatment are among the most important services we provide.

What Is Skin Cancer Screening?

When you have a full-body check-up, a member of our dermatology team will perform an evaluation. Drawing from our extensive training and years of experience, we can quickly identify those lesions that are cause for concern. Any potentially cancerous lesion will be tested and evaluated by one of our dermatopathology specialists.

What are the Different Types of Skin Cancer?

There are several different types of skin cancer but we tend to see three particular types much more often than the others. These types of skin cancer are named after the cells that become abnormal. They include:

  • Basal cell carcinoma
  • Squamous cell carcinoma
  • Melanoma
  • Actinic keratosis, a type of pre-cancerous growth

Additional, far less common types of skin cancer include:

  • Sebaceous carcinoma
  • Merkel cell carcinoma
  • Cutaneous T-cell lymphoma
  • Dermatofibrosarcoma protuberans (DFSP)

What Causes Skin Cancer?

Numerous studies suggest that exposure to ultraviolet (UV) light is the leading factor that contributes to skin cancer. When the skin is exposed to ultraviolet light, found in the sunshine as well as tanning lamps, the DNA in the skin can sustain damage. This is especially relevant to tanning bed use and sunburns that cause blisters or peeling. DNA is involved in gene expression and cellular development. When the DNA is damaged, the cells may not grow and divide normally. Some of these cells become cancer cells.

How is Skin Cancer Diagnosed?

To diagnose skin cancer, your doctor will begin with a thorough skin cancer screening. This visual examination of your skin may involve the use of a special instrument that magnifies the visual field. If a growth has the characteristics of skin cancer, the doctor will perform a biopsy. This test obtains a sampling of skin cells or tissue that can be examined under a microscope by a trained pathologist. Biopsies can be done in a number of different ways. The most common is to anesthetize the area of study with an injection of numbing medication and then excise a small piece of tissue. Excisional biopsies allow the pathologist to examine multiple layers of the skin. Another way to biopsy a growth is to shave off the uppermost layers of the growth. Finally, a doctor may use a "punch" instrument as another method of obtaining multiple layers of tissue. In some cases, a biopsy may also be done on suspicious lymph nodes.

Your board-certified dermatologist has considerable training in the performance of skin cancer examinations and biopsies. We'll discuss which type of test is most appropriate for you based on the characteristics of your suspicious growth, including its location and size.

What Treatment is Best for Me?

Several skin cancer treatments may be considered after receiving an accurate diagnosis. Your doctor can walk you through which options may be appropriate based on your case. These include:

  • Minor surgical excision
  • Mohs micrographic surgery
  • Cryotherapy (freezing)
  • Curettage and electrodesiccation
  • Photodynamic therapy (usually used for precancerous lesions)
  • Radiation therapy
  • Chemotherapy

You aren't on your own to determine the type of skin cancer treatment that you should choose. Your doctor will likely make recommendations that consider the size, severity, and location of your cancer.

How Can I Reduce My Risk of Getting Skin Cancer?

The number one way to reduce your risk of getting skin cancer is to avoid excessive sun exposure. Living in beautiful Boca Raton, you may love spending time outdoors. You still can! Just be diligent with the application of broad-spectrum SPF 30 sunscreen. Keep in mind that you'll need to reapply sunscreen every few hours if you're spending a day at the beach or another outdoor area. In these instances, it is also wise to wear a hat that shades your ears, face, and neck. Lightweight, long-sleeved clothing can protect your skin, as can lightweight pants, as can finding some shade during the brightest hours of the day. Finally, monthly self-examinations are strongly encouraged by skin cancer specialists. These periodic exams help you more quickly spot those unusual spots that could spell trouble down the line.

How Do I Examine Myself for Skin Cancer?

Your monthly skin checks don't need to be complicated or take much time at all. After your first few, you'll have a better awareness of your skin and the spots or moles that are normal for you. To perform your self-exam, you'll need to completely disrobe. Begin by looking directly at the skin on a body part. It can help to start with your feet (look at the soles and in between your toes, too!) and work your way up from there. If there are areas that you cannot observe directly, use a handheld mirror. For example, to observe the skin on your back, stand with your back to a larger mirror and look at your reflection in a handheld mirror. You may also need to use a handheld mirror to check your scalp and genital area. As you observe your skin, take note of the color of your moles and spots, their color, and their shape. Note if any spots have texture. From month to month, you'll be able to notice if changes occur in any areas. Any spots or moles that look questionable should be examined by your dermatologist.

If the lesion is malignant, we provide a customized treatment plan, depending on the type of cancer, as well as its size, shape, and location. We will evaluate your current health and review your medical history to ensure that you receive safe and effective treatment.

Skin Lesion Removal

Many cancerous lesions can be removed in a simple procedure using a scalpel. Because skin cancer typically extends beyond the visible portion, additional tissue is removed. Following surgery, the removed tissue will be sent to our specially trained pathologist for evaluation. If cancerous cells are discovered in the borders, a second procedure will be needed. If the borders are clear, the process is complete.
