Squamous Cell Carcinoma

Squamous cell carcinoma (SCC) is the second most common type of skin cancer and develops in squamous cells, which make up the outer layer of the skin. This squamous cell carcinoma definition reflects how the cancer forms when these cells grow abnormally, most often due to long-term sun exposure. According to the American Academy of Dermatology, squamous cell carcinoma frequently appears on areas of the body that receive regular sun exposure, such as the face, ears, lips, neck, hands, and arms.

One of the main answers to what causes squamous cell carcinoma is cumulative ultraviolet (UV) radiation from the sun or tanning beds. SCC can also develop on previously damaged skin, including areas affected by burns, scars, or prior radiation. While many cases grow slowly, squamous cell carcinoma has a higher risk of spreading than basal cell carcinoma if left untreated, making early diagnosis important.

Squamous Cell Carcinoma Symptoms

Squamous cell carcinoma symptoms can vary in appearance and may resemble other skin conditions. Common signs include:

  • A hard, scaly, or crusted reddish bump or patch
  • An open sore that itches, bleeds, crusts, and returns
  • Thick, rough, or scaly patches, especially on the lips
  • A lesion that does not heal or continues to change over time

Because there are different types of squamous cell carcinoma, symptoms may vary depending on how deeply the cancer has grown. Any persistent or changing skin lesion should be evaluated by a dermatologist.

Squamous Cell Carcinoma Diagnosis and Treatment in Texas

Diagnosis begins with a thorough skin examination performed by a dermatologist. If a suspicious lesion is identified, a skin biopsy is performed to confirm whether squamous cell carcinoma is present and to assess its depth and characteristics. Identifying the specific type and extent of SCC helps guide appropriate care and determine whether additional evaluation is needed.

Squamous cell skin carcinoma treatments depend on the size, location, and depth of the cancer. Your dermatologist will determine how to treat squamous cell carcinoma based on your specific diagnosis.

  • Surgical excision: Removes the cancer along with a margin of healthy tissue.
  • Mohs surgery for squamous cell carcinoma: A precise technique used for high-risk or recurrent lesions while preserving healthy skin.
  • Curettage and electrodesiccation: Combines curettage surgery for skin cancer with an electrodesiccation procedure to destroy remaining cancer cells, often used for smaller or superficial lesions.
  • Radiation therapy: May be recommended in select cases when surgery is not appropriate.

Squamous cell carcinoma diagnosis, evaluation, and treatment are available at all Bare Dermatology locations across Texas.

FAQ About Squamous Cell Carcinoma

Squamous cell carcinoma often appears as a firm, scaly, or crusted red bump, patch, or sore that may bleed or fail to heal. It commonly develops on sun-exposed areas such as the face, ears, lips, neck, hands, and arms. Because its appearance can vary, any persistent or changing lesion should be evaluated by a dermatologist.

The rate at which squamous cell carcinoma spreads varies. Many cases grow slowly, but some can become more aggressive and spread to deeper tissues or nearby lymph nodes if left untreated. Early diagnosis and treatment help reduce the risk of spread.

Delaying treatment can allow squamous cell carcinoma to grow larger and become more difficult to treat. While some lesions may develop gradually, prompt evaluation and treatment are recommended once SCC is diagnosed to lower the risk of complications.

Recovery after squamous cell carcinoma treatment varies based on the size and location of the lesion and the type of treatment used. Most patients heal well with proper wound care and follow post-procedure instructions provided by their dermatologist. Regular follow-up skin exams are important, as patients with a history of squamous cell carcinoma have a higher risk of developing additional skin cancers. Ongoing monitoring helps support early detection and long-term skin health.

You should see a dermatologist if you notice a new, changing, or non-healing lesion on your skin, especially in areas frequently exposed to the sun. Evaluation is particularly important if a spot becomes scaly, crusted, bleeds easily, or continues to return after healing. Early assessment supports timely diagnosis and helps reduce the risk of complications.

Squamous cell carcinoma evaluation and treatment are available through in-office consultations at Bare Dermatology locations across Texas. Bare Dermatology also offers a full range of medical and aesthetic dermatology services.
