Basal Cell Carcinoma: What Is It and How Do You Treat It?

Posted on: November 10th, 2023 by Michael Sotiriou

Have you ever noticed an unusual growth or sore on your skin? It’s important not to ignore any changes in your skin, as they could potentially be signs of a serious condition, such as skin cancer. Basal Cell Carcinoma (BCC) is the most common type of skin cancer, with over 4 million cases diagnosed in the United States each year. In this comprehensive guide, we will delve into everything you need to know about BCC, including its causes, symptoms, diagnosis, and treatment options.

What Is Basal Cell Carcinoma?

Basal Cell Carcinoma, or BCC, is a type of skin cancer that originates in the basal cells, a type of cell located in the lower part of the epidermis. These cells are responsible for producing new skin cells. BCC typically occurs on sun-exposed areas of the body, such as the face, neck, and arms. It usually appears as a shiny, pearly bump or a non-healing sore that may bleed easily. Although BCC rarely spreads to other parts of the body, it can cause significant damage if left untreated.

Causes and Risk Factors

Excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds is the primary cause of BCC. Prolonged exposure to UV rays damages the DNA in the skin cells, leading to abnormal cell growth and the development of cancer. Other risk factors for BCC include:

  • Fair skin
  • Family history of skin cancer
  • Chronic sun exposure or outdoor occupations
  • Having a weakened immune system
  • Exposure to certain chemicals or radiation
  • Previous radiation therapy

While anyone can develop BCC, those with fair skin and a history of sunburns or intense sun exposure are at a higher risk.

Symptoms of Basal Cell Carcinoma

Basal Cell Carcinoma often presents as slow-growing and painless growths on the skin. The appearance may vary depending on the subtype of BCC, but common signs and symptoms include:

  1. Shiny, pearly, or translucent bump on the skin
  2. Pink or red patches that are slightly raised
  3. Open sore or ulcer that does not heal
  4. Elevated growth with a central depression
  5. Oozing or crusting spots
  6. Scar-like area with poorly defined borders

It is essential to remember that not all skin abnormalities are cancerous, but any new or changing growth should be evaluated by a dermatologist.

Diagnosing Basal Cell Carcinoma

When you visit a dermatologist with concerns about a skin abnormality, they will perform a thorough examination and may use various diagnostic tools to confirm the presence of BCC. These may include:

  1. Visual Inspection: The dermatologist will examine the skin lesion, noting its size, color, and texture.
  2. Dermoscopy: This non-invasive procedure involves using a special magnifying tool called a dermatoscope to examine the lesion in more detail.
  3. Skin Biopsy: A small sample of the affected skin will be taken and sent to a laboratory for analysis. The biopsy will determine whether cancer cells are present and help identify the subtype of BCC.

Once a diagnosis of Basal Cell Carcinoma has been confirmed, the dermatologist will discuss the appropriate treatment options based on the specific characteristics of the tumor.

Treatment Options

The treatment approach for Basal Cell Carcinoma depends on several factors, including the size, location, and subtype of the tumor, as well as the patient’s overall health. The most common treatment options for BCC include:

1. Surgical Excision

Surgical excision involves cutting out the entire tumor along with a margin of healthy skin. This method is often used for smaller BCCs, those located on low risk areas such as the trunk or extremities, or those with well-defined borders. In some cases, the wound may be closed with sutures or a skin graft.

2. Mohs Micrographic Surgery

Mohs micrographic surgery is a specialized surgical technique used for large or high-risk BCCs. During this procedure, the tumor is removed layer by layer, with each layer examined under a microscope for cancer cells. This precise approach ensures that all cancer cells are removed while preserving as much healthy tissue as possible.

3. Cryosurgery

Cryosurgery involves freezing the cancer cells with liquid nitrogen, causing the tumor to be destroyed. This method is typically used for small BCCs on the surface of the skin.

4. Curettage and Electrodessication

Curettage involves scraping the tumor off the skin using a spoon-shaped instrument called a curette, while electrodessication uses an electric current to destroy any remaining cancer cells and seal the wound. This procedure is suitable for superficial BCCs.

5. Topical Medications

For small and superficial BCCs, topical medications such as creams or gels containing imiquimod or fluorouracil may be prescribed. These medications work by stimulating the body’s immune response to target and destroy the cancer cells.

6. Radiation Therapy

In rare cases where surgery is not feasible, radiation therapy may be recommended. It involves targeting high-energy radiation directly at the tumor to destroy the cancer cells.

The choice of treatment will be determined by the dermatologist based on the individual patient’s needs and the characteristics of the tumor.

Prevention and Prognosis

While it may not be possible to prevent all cases of Basal Cell Carcinoma, there are steps you can take to reduce your risk:

  1. Limit sun exposure, especially during peak hours between 10 a.m. and 4 p.m.
  2. Wear protective clothing, such as wide-brimmed hats and long sleeves, when outdoors.
  3. Apply broad-spectrum sunscreen with a Sun Protection Factor (SPF) of 30 or higher.
  4. Avoid indoor tanning beds.
  5. Regularly examine your skin for any changes or suspicious growths.

When detected early, Basal Cell Carcinoma has an excellent prognosis, with a high cure rate. Regular self-checks and annual skin examinations by a dermatologist are crucial for early detection and prompt treatment.


Basal Cell Carcinoma is a common and treatable form of skin cancer. Early detection and appropriate treatment are key to achieving favorable outcomes. If you notice any changes in your skin, such as new growths or non-healing sores, consult with a dermatologist for a thorough evaluation. Remember, protecting your skin from excessive sun exposure and adopting sun-safe habits are vital for maintaining healthy skin and reducing the risk of BCC and other skin cancers. Stay vigilant, take proactive measures, and prioritize your skin health.
