Squamous Cell Carcinoma
What is Squamous Cell Carcinoma (SCC)?
Squamous Cell Carcinoma is a common skin cancer. About 700,000 new cases are diagnosed annually in the United States.
Squamous cell carcinoma can develop anywhere, including inside the mouth and on the genitalia. It most frequently appears on the scalp, face, ears and back of hands. Squamous cell carcinoma tends to develop among fair-skinned, middle-aged, and elderly people who have a history of sun exposure. In some cases, it evolves from actinic keratoses, dry scaly lesions that can be flesh-colored, reddish-brown or yellow black, and which appear on skin that is rough or leathery. Actinic keratoses spots are considered to be precancerous.
What does a Squamous Cell Carcinoma look like?
Squamous Cell Carcinomas can present in a number of different ways:
A bump or lump on the skin that can feel rough.
A dome-shaped or crusty bump that can bleed.
A sore that continuously heals and re-opens
Flat red scaly patch that grows slowly.
What are the causes of Squamous Cell Carcinoma and who gets it?
Risk factors for squamous carcinoma include having fair skin, sun exposure, and exposure to ultraviolet radiation (as in tanning beds). In addition, exposure to cancer-causing chemicals (such as Arsenic, tar, insecticides) and history of tobacco use can increase your risk. If you have been diagnosed with a precancerous skin lesion called an Actinic Keratosis, you are more likely to develop a SCC.
When should I see a dermatologist?
You should see a dermatologist for evaluation if you have a bump or a scaly red patch that:
Won’t heal, or heals and returns
Oozes or crusts over
Lump that feels rough
How is a squamous cell carcinoma diagnosed?
Diagnosing squamous cell carcinoma requires a simple skin biopsy that can be performed in the office by a dermatologist during your visit. During the skin biopsy, the suspicious lesion is removed and the sample will be sent to a laboratory to be analyzed under a microscope.
What are treatments for squamous cell carcinoma?
Some of the treatments for SCC include
Excision — This is a surgical treatment where the tumor is removed and cut out with some normal-looking skin around the tumor. Your dermatologist will stitch up the area after the excision. This is an outpatient procedure and a common way to treat SCC. The removed skin is also sent out to the laboratory to ensure that the skin is free of cancer.
Curettage and Desiccation — This in-office treatment involves using a small metal instrument (called a curette) to scrape out the tumor along with an application of an electric current into the tissue to kill off any remaining cancer cells.
Mohs Micrographic Surgery — This specialized surgical treatment is indicated for large tumors and for SCC in certain anatomic locations. Mohs Surgery combines removal of cancerous tissue with microscopic review while the surgery takes place. By mapping the diseased tissue layer by layer, less healthy skin is damaged when removing the tumor. It has the highest cure rate for SCC. Your dermatologist will let you know if Mohs surgery is recommended.
Prescription Medicated Creams — These creams can be applied at home. They stimulate the body's natural immune system over the course of weeks. The most common medications are imiquimod or 5-fluorouracil.
Cryosurgery — Some squamous cell carcinomas respond to cryosurgery, where liquid nitrogen is used to freeze off the tumor.
Radiation Therapy — Radiation therapy is used for difficult-to-treat tumors, either because of their location, severity, or persistence. If radiation therapy is a treatment option, you will receive a referral to a radiation oncologist.
