Overview

Understanding Squamous Cell Carcinoma

Squamous cell carcinoma or cutaneous squamous carcinoma is a common cancer that starts in the middle and outer layers of the skin. More than 200,000 people in the U.S. are diagnosed with squamous cell carcinoma each year. Although not usually life-threatening, squamous cell carcinoma can be very aggressive. Untreated, squamous cell carcinoma can grow large and metastasize to other parts of your body.

Who’s at Risk for Skin Cancer?

While skin cancers typically form in areas with high sun exposure, such as the face, ears, scalp, arms, neck or back of the hands, squamous cell carcinoma can develop in almost any place on your body. Anyone can get squamous cell carcinoma, but it is most common in people who:

  • Don’t use sunscreen 
  • Live in a sunny place 
  • Have light-colored eyes 
  • Spend a lot of time outdoors 
  • Have naturally red or blonde hair 
  • Have family members who have had skin cancer 
  • Have a history of a lot of sun exposure or sunburn 
  • Have xeroderma pigmentosum, a rare genetic disorder 
  • Have a personal history of precancerous lesions or skin cancer 
  • Have fair skin that tends to freckle or burn when exposed to sunlight 
  • Have a weakened immune system or who take medicines that suppress the immune system 

Squamous cell carcinoma is aggressive and can spread to your lymph nodes or other organs, and can be fatal if left untreated.

Symptoms

Symptoms of Squamous Cell Carcinoma

Because squamous cell carcinoma can occur anywhere, you should examine your body regularly for signs. It is good to have a partner check places that you cannot see to ensure you don’t have any indications of squamous cell carcinoma.

Signs of squamous cell carcinoma include: 

Group 24

Flat sore with a scaly crust

Group 9

Raised area or new sore on an old scar

Group 23

Firm, red nodule anywhere on your body

icon 27

Red sore or rough patch inside your mouth

icon 3

Rough, scaly patch on your lip that may turn into an open sore 

Wart like sore or red, raised patch on or in your anus or genitals

Diagnosis

Squamous Cell Carcinoma Diagnosis

Diagnosis of squamous cell carcinoma begins with an examination of your skin. Besides questions about your and your family’s medical history, your doctor may ask questions about when you first noticed it, if it has changed, or if it is bothersome. If your doctor suspects you have squamous cell carcinoma, they may order additional tests, such as a biopsy. Before the biopsy, the doctor will numb the area where they will take a small sample of your skin to analyze under a microscope. 

Treatments

Squamous Cell Carcinoma Treatments

Treatment for squamous cell carcinoma depends on its size, stage, location and the patient’s overall health.

Small Squamous Cell Carcinomas

Small Squamous Cell Carcinomas

Small squamous cell carcinomas are usually early-stage and easily treated with minor surgery.

Surgical excision

Surgical excision can remove (excise) cancer from the affected area and part of the healthy tissue. The surgeon may also remove nearby lymph nodes depending upon how advanced the cancer is. Learn more >>

Chemotherapy creams and ointments 

Chemotherapy creams and ointments applied directly to the lesion (topically) in early-stage lesions.

Curettage & electrodessication (C & E)

Curettage & electrodessication (C & E) involves scraping away the surface of the carcinoma with a curet (a small spoon-shaped device). After scraping away the lesion, your doctor will sear the base of the squamous cell carcinoma with an electric needle.

Advanced Squamous Cell Carcinomas

Advanced Squamous Cell Carcinomas

Mohs surgery

Mohs surgery removes the squamous cell carcinoma layer-by-layer so the surgeon can examine each layer until all abnormal cells are removed. Mohs surgery is appropriate if squamous cell carcinoma is recurring on a sensitive area such as the face or on larger growths to minimize the removal of healthy tissue while still getting the entire growth. Learn more >>

Radiation therapy

Radiation therapy uses high-energy beams where surgery isn’t feasible or in cases where surgery cannot remove the entire growth.

Metastasized Squamous Cell Carcinomas

Metastasized Squamous Cell Carcinomas

If the carcinoma has spread to lymph nodes or other parts of the body, then your doctor may consider three additional options. 

Chemotherapy

Chemotherapy is delivered orally, intravenously or both and uses a mix of chemicals to target any quickly dividing cells. 

Targeted therapy

Targeted therapy works differently from chemotherapy by targeting weaknesses in squamous cell carcinomas. 

Immunotherapy 

Immunotherapy drugs can help fight cancer. Cancer cells sometimes produce proteins that help them hide from your immune system. Immunotherapy drugs block the ability of cancer to hide, allowing your body to see the cancerous cells.

Frequently Asked Questions (FAQs) About Squamous Cell Carcinoma

What is squamous cell carcinoma (SCC)?

Squamous cell carcinoma, often abbreviated as SCC, is a form of skin cancer that arises in the squamous cells of the skin’s outer layers.

What are the common symptoms of squamous cell carcinoma?

Common symptoms encompass flat sores with a scaly crust, raised areas or new sores on old scars, firm, red nodules on the skin, red sores or rough patches inside the mouth, rough, scaly patches on the lips, and wart-like sores or red raised patches on the anus or genitals.

Who is at risk for squamous cell carcinoma?

While it can affect anyone, it is more prevalent in individuals with light-colored eyes, those residing in sun-exposed areas, frequent outdoor activities, family history of skin cancer, or fair skin prone to sunburn and freckling.

How is squamous cell carcinoma diagnosed?

Diagnosis typically commences with a thorough skin examination. In the presence of symptoms, a biopsy is often performed, involving the microscopic analysis of a small skin sample.

What are the treatment options for squamous cell carcinoma?

Treatment depends on factors like size, stage, and location. Small SCCs can be treated with surgical excision, topical chemotherapy creams, or curettage & electrodessication. Advanced cases may necessitate Mohs surgery or radiation therapy. In cases of metastasis, chemotherapy, targeted therapy, or immunotherapy may be considered.
