Squamous Cell Carcinoma

As the second-most common type of skin cancer, it is important for patients to understand the signs and symptoms of squamous cell carcinoma. Thankfully, this type of skin cancer is easily treatable when it is diagnosed at an early stage. If you notice any signs of skin cancer, you should schedule an appointment with an educated and experienced dermatologist like Dr. Liz Damstetter as soon as possible.

What is Squamous Cell Carcinoma?

Squamous cell carcinoma is the second-most common type of skin cancer. In this type of skin cancer, the skin’s squamous cells grow abnormally and uncontrollably. These cells make up the middle and outer layers of the epidermis.

What Causes Squamous Cell Carcinoma?

A majority of squamous cell carcinoma cases are caused by damage from UV rays. This is a result of excess sun exposure or indoor tanning over time. However, other forms of damage can also contribute to squamous cell carcinoma. The general cause of this type of cancer is damage to the DNA within the skin’s squamous cells, resulting in abnormal and uncontrolled growth.

While anyone could develop squamous cell carcinoma, the disease is more common among patients with the following risk factors:

  • Fair skin, especially that which burns or freckles easily
  • Red or blond hair and light-colored eyes
  • Excess sun exposure, especially due to outdoor work or hobbies
  • History of sunburns
  • Personal or family history of skin cancer or precancerous lesions
  • Weakened immune system
  • Genetic conditions including xeroderma pigmentosum

Squamous Cell Carcinoma Symptoms

Squamous cell carcinomas may appear as firm red nodules on the skin. They may also be flat or raised sores that can be rough, scaly, or wart-like. When squamous cell carcinoma presents as an open sore, it will not heal for some time. If you notice that a rough patch of skin or open sore does not heal for a month or more, you should see a dermatologist as soon as possible.

Squamous cell carcinoma is most likely in areas that are frequently exposed to the sun, such as the face, neck, scalp, forearms, or the backs of the hands. However, they can also occur in areas that are harder to see, including the inside of the mouth, the bottoms of the feet, or the genitals.

Squamous Cell Carcinoma Treatment

If you or Dr. Damstetter suspect you may have squamous cell carcinoma, the next step is a biopsy to confirm a diagnosis. This involves removing a small amount of tissue that can be examined in a lab to test for squamous cell carcinoma.

If you are diagnosed with squamous cell carcinoma, Dr. Damstetter will explain your best treatment options. Most common treatments include:

  • Excision, or surgically removing the cancerous cells using a scalpel or similar tool

Curettage and electrodessication, or scraping the cancerous tissue away using a curette before searing the remaining tissue using an electric needle to destroy any remaining cancer cells

  • Cryosurgery, or freezing the cancerous tissue using liquid nitrogen
  • Photodynamic therapy, or applying a light-reactive medication to the skin before targeting the cancer cells using a laser light

In more advanced stages of squamous cell carcinoma, additional treatments including radiation therapy or chemotherapy may be necessary. However, this is uncommon if the squamous cell carcinoma is diagnosed early by a board-certified dermatologist.
