How Is Basal Cell Different from Squamous Cell Carcinoma?

Published On

Basal Cell vs. Squamous Cell Skin Cancer | CA Dermatology

Basal cell and squamous cell carcinoma are two common types of skin cancer, each with its own characteristics and treatment options. Basal cell carcinoma arises from the basal cells in the skin’s outermost layer, while squamous cell carcinoma originates from the squamous cells. Understanding the differences between these two malignancies is critical for accurate diagnosis and treatment. Let’s talk about the differences between squamous cell and basal cell carcinoma.

What is Basal Cell Carcinoma?

Basal cell carcinoma (BCC) is the most prevalent form of skin cancer, originating in the epidermis’s basal cells, the skin’s outer layer. It usually develops due to prolonged exposure to ultraviolet radiation from sunlight or tanning beds. Although it rarely spreads to other parts of the body, it can be locally invasive and cause disfigurement if left untreated.

How Serious Is Basal Cell Carcinoma?

While Basal Cell Carcinoma is generally slow-growing and rarely metastasizes, it can still cause significant damage if not promptly addressed. If neglected, it can invade surrounding tissues, leading to disfigurement or functional impairment, particularly in areas like the face where it commonly occurs.

What is Squamous Cell Carcinoma?

Squamous Cell Carcinoma (SCC) arises from the squamous cells, which compose the skin’s upper layers. Like Basal Cell Carcinoma, it is primarily caused by UV radiation exposure. SCC tends to grow more rapidly than Basal Cell Carcinoma and has a higher potential to metastasize, especially if left untreated. It often appears as a scaly or crusty bump, which may bleed easily.

How Serious Is Squamous Cell Carcinoma?

Squamous cell carcinoma is considered more serious than basal cell carcinoma due to its higher propensity to spread. While it typically doesn’t metastasize as quickly as some other types of cancer, if left untreated, it can invade surrounding tissues, leading to more severe consequences. Prompt diagnosis and treatment are essential to prevent its progression.

Other Types of Skin Cancer

Melanoma is another type of skin cancer. Unlike BCC and SCC, melanoma originates in the melanocytes, the cells responsible for the pigment in the skin. Melanoma is less common but more aggressive, with a higher likelihood of metastasis.

Basal Cell vs Squamous Cell Skin Cancer: Identification & Treatment

Identification of Basal Cell Carcinoma

Pearly or Waxy Bump: Basal cell carcinomas often appear as raised, pearly, or waxy bumps on the skin. These bumps may have a translucent or shiny quality and can vary in size from a small nodule to a larger mass.

Flat, Flesh-Colored Lesion: Another characteristic feature of basal cell carcinoma is the presence of flat, flesh-colored lesions on the skin. These lesions may resemble a scar or a slightly raised area and can be easily overlooked if they blend in with the surrounding skin.

Occasionally Bleeds or Develops a Crust: Basal cell carcinomas may exhibit signs of ulceration, bleeding, or crusting, especially if irritated or traumatized. These symptoms can occur intermittently and may prompt individuals to seek medical attention.

Typically Found on Sun-Exposed Areas: Basal cell carcinomas predominantly occur on sun-exposed areas of the body, such as the face, neck, scalp, ears, and shoulders. Prolonged exposure to ultraviolet radiation from the sun is a significant risk factor for the development of basal cell carcinoma.

Identification of Squamous Cell Carcinoma

Red Nodule: Squamous cell carcinomas often present as red nodules on the skin. These nodules may feel hard to the touch and can vary in size from a small bump to a larger, raised mass.

Scaly, Crusted Patch: Another characteristic feature of squamous cell carcinoma is the presence of scaly or crusted patches on the skin. These patches may be rough in texture and can range in color from red to brown to tan.

Resembles a Wart or an Open Sore: Squamous cell carcinomas may resemble a wart, with a rough, elevated surface or an open sore that fails to heal. These lesions may be tender or painful, especially if they become ulcerated or infected.

Commonly Occurs on Sun-Exposed Skin: Similar to basal cell carcinoma, squamous cell carcinoma is frequently found on sun-exposed body areas, such as the face, ears, lips, hands, and forearms. Chronic sun exposure, as well as other factors such as immunosuppression and exposure to carcinogens, increases the risk of developing squamous cell carcinoma.

Basal and Squamous Cell Skin Cancer Treatment  

Both basal and squamous cell carcinoma treatment aims to remove the cancerous cells while preserving surrounding healthy tissue. Treatment choice depends on various factors, including the type, size, location, tumor stage, and the patient’s overall health and preferences.

Surgical Excision

Surgical excision involves removing the cancerous lesion along with a margin of healthy tissue to ensure complete removal of the tumor. It is a common treatment for both basal and squamous cell carcinoma.

Mohs Micrographic Surgery

Mohs micrographic surgery stands out as an intricately tailored approach to combatting skin cancer, particularly targeting lesions with elevated recurrence probabilities or those situated in aesthetically delicate regions. This specialized technique meticulously entails the systematic removal of successive thin layers of tissue, each promptly scrutinized under a microscope, until the absence of malignant cells is confirmed, thus adeptly curbing the proliferation of cancerous growths while impeccably preserving surrounding healthy tissue.

Radiation Therapy

Utilizing potent high-energy beams, radiation therapy orchestrates a precision strike against cancer cells, obliterating them with clinical finesse. This therapeutic modality emerges as a frontline recommendation for basal cell or squamous cell carcinoma, particularly when surgical intervention proves impractical. Additionally, it serves as a pivotal adjunct to surgical excision, amplifying treatment efficacy and mitigating the risk of cancer recurrence.

Topical Medications

Topical medications such as imiquimod and 5-fluorouracil (5-FU) may be prescribed for superficial basal cell carcinoma or squamous cell carcinoma, particularly in cases where surgery is not suitable or for patients who prefer non-invasive treatment options.

Basal and squamous cell carcinoma are two distinct types of skin cancer, each with its characteristics and potential consequences. While BCC tends to grow slowly and rarely metastasize, SCC is more aggressive and has a higher propensity to spread. Early detection and treatment are crucial for both types of cancer to prevent complications and ensure the best possible outcome for patients.
