Basal cell carcinoma (BCC), also known as basalioma, is the most common type of skin cancer in the UK. It falls under the category of non-melanoma skin cancer (NMSC) and accounts for approximately 75% of all skin cancers in the UK.
It appears as abnormal, uncontrolled growths or lesions that arise in the skin’s basal cells, which line the outermost layer of the skin. The tumor grows slowly and only on the skin, and it almost never grows beyond the original tumor site.

Basal Cell Carcinoma (BCC) on the chest showing a small, red, slightly raised lesion, indicative of skin cancer (ICD-10 C44.91)
Fair-skinned individuals, particularly those with blonde or red hair, light eyes, and who burn rather than tan, are most at risk.
Other forms of skin cancer: Squamous cell carcinoma
Symptoms
Basal cell carcinoma is generally found on exposed skin areas, especially on the face, but also on the trunk and limbs. BCC often appears as a persistent scab or sore that fails to heal, a shiny, pearly lump, or a scaly red patch. It may bleed or ulcerate over time.

Here are the main forms of this skin cancer:
Nodular basal cell carcinoma
Most common. Well-defined, solid, a shiny facial lesion with prominent blood vessels which may bleed easily.
Superficial basal cell carcinoma
Persistent red patch of skin that may bleed easily. Often found on the trunk.
Morphoeic basal cell carcinoma
Less common. More aggressive, looks like a flat scar with indistinct borders, often on the face.
