Basal Cell Carcinoma
Urgent
Basal cell carcinoma is the most common type of skin cancer and develops from basal cells in the skin. It most often occurs on areas exposed to ultraviolet radiation, particularly the face, scalp, ears, neck, and arms. Lesions may appear as a pearly or shiny bump, a persistent sore, a scaly patch, or an area that repeatedly bleeds or heals and returns. Early evaluation helps guide treatment.

When to Seek Medical Attention
Basal cell carcinoma should be medically evaluated promptly when a new or changing skin growth, persistent sore, bleeding lesion, or non-healing area is present. Early assessment is important because untreated lesions can grow deeper and cause local tissue damage. Emergency care is generally not required unless there is severe bleeding, infection, or another acute complication.

Overview

Causes 1
Basal cell carcinoma is primarily associated with cumulative ultraviolet radiation from sunlight or tanning devices. Repeated or prolonged exposure can cause DNA damage in basal cells and promote abnormal growth. Other contributing factors include previous radiation exposure, certain inherited conditions, a history of skin cancer, and reduced immune function. The cancer usually grows slowly and rarely spreads to distant organs, but untreated lesions can invade nearby tissue.
Genetics
Risk Factors
Risk increases with cumulative ultraviolet exposure, frequent sunburns, use of tanning beds, fair skin, light-colored eyes, a tendency to burn rather than tan, and a history of significant sun exposure. Previous basal cell or other skin cancers increase future risk. Immunosuppression, previous radiation therapy, and certain inherited disorders can also increase susceptibility. Risk generally rises with age because ultraviolet damage accumulates over time.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Basal cell carcinoma is usually suspected from the appearance of a persistent or changing skin lesion and confirmed by biopsy. A healthcare professional examines the lesion and surrounding skin and may use dermoscopy for additional visual assessment. A biopsy provides tissue for microscopic examination and establishes the diagnosis. Further imaging is generally reserved for lesions that are unusually large, deeply invasive, recurrent, or suspected of involving important nearby structures.
Prevention
Key Prevention Tips
The most important preventive measure is protection from ultraviolet radiation
Using broad-spectrum sunscreen, wearing protective clothing and hats, seeking shade, and avoiding tanning beds can reduce cumulative UV exposure
Regular awareness of changing or persistent skin lesions can promote early detection
People with previous skin cancer or substantial sun exposure may benefit from regular professional skin examinations and should report suspicious lesions promptly
Prevention Guidance
