Basal Cell Carcinoma
Diagnosis and Treatment of Basal Cell Carcinoma
Basal cell carcinoma (BCC) is the most common form of skin cancer. It develops from cells in the basal layer of the skin and is most often related to cumulative sun exposure. Although BCC typically grows slowly and rarely spreads to other parts of the body, early detection and treatment are important to prevent local tissue damage.
What Is Basal Cell Carcinoma?
Basal cell carcinoma commonly develops on sun-exposed areas of the skin, including the face, ears, scalp, neck, and arms. It may appear as a new growth or a sore that does not heal.
BCC can present in several forms and may resemble benign skin lesions, which is why careful dermatologic evaluation is important.
Common Signs of Basal Cell Carcinoma
Basal cell carcinoma may present with a variety of clinical features, including:
A pearly or translucent bump
A pink or flesh-colored growth
A sore that does not heal or repeatedly bleeds
A flat, scaly patch on the skin
A lesion with rolled borders or visible blood vessels
Any persistent or changing lesion should be evaluated.
Risk Factors for Basal Cell Carcinoma
Factors that may increase the risk of BCC include:
- Cumulative sun exposure
- Fair skin, light hair, or light eye color
- History of sunburns
- Increasing age
- Personal history of skin cancer
Regular skin examinations are important for individuals at increased risk.
Diagnosis of Basal Cell Carcinoma
Basal cell carcinoma is diagnosed through dermatologic evaluation.
Dermatologic Examination
A comprehensive skin examination includes evaluation of suspicious lesions across the skin. Dermoscopy may be used to assess specific features of a lesion.
Skin Biopsy
If a lesion appears suspicious, a biopsy is performed to confirm the diagnosis. The sample is examined microscopically to determine the type and characteristics of the tumor.
Treatment of Basal Cell Carcinoma
Treatment is based on the size, location, and subtype of the tumor, as well as individual patient factors.
Surgical Excision
Surgical excision involves removal of the tumor along with a margin of surrounding skin to ensure complete removal. This is a commonly used and effective treatment for many basal cell carcinomas.
Electrodesiccation and Curettage (ED&C)
Electrodesiccation and curettage involves gently scraping away the tumor and treating the area with controlled electrical energy to destroy remaining cancer cells. This technique is often used for superficial or low-risk lesions.
Mohs Micrographic Surgery
Mohs surgery is a specialized technique used for certain basal cell carcinomas, particularly those located in cosmetically sensitive areas or those with higher risk features. The tumor is removed in stages, with each layer examined under a microscope to ensure complete removal while preserving surrounding healthy tissue.
Topical Treatments
In select cases, topical medications may be used to treat superficial basal cell carcinomas. These treatments are applied directly to the skin and work by targeting abnormal cells over time.
Follow-Up and Surveillance
After treatment, regular dermatologic follow-up is important to monitor for recurrence and detect new skin cancers.
Follow-up care may include:
- Routine total body skin examinations
- Monitoring treated areas for recurrence
- Evaluation of new or changing lesions
Individuals with a history of BCC have an increased risk of developing additional skin cancers.
Prevention and Early Detection
Preventive measures and early detection play an important role in managing skin cancer risk.
Recommendations include:
- Regular skin examinations
- Daily use of sunscreen and sun protection
- Avoidance of excessive ultraviolet (UV) exposure
- Monitoring the skin for new or changing lesions
When to Seek Evaluation
Evaluation is recommended for:
A new or persistent skin lesion
A sore that does not heal
A lesion that bleeds or crusts repeatedly
Any changing or unusual skin growth
Schedule a Skin Examination
Early detection and treatment of basal cell carcinoma help prevent progression and minimize tissue damage.
