If you've noticed a small, pearly bump or a scab that won't quite heal, it's worth knowing about basal cell carcinoma. Basal cell carcinoma (BCC) is the most common form of skin cancer in the UK, accounting for around 70% of all skin cancer diagnoses, and it rarely spreads if caught and treated early. Understanding what basal cell carcinoma looks like, why it develops, and how it's treated on the NHS can make the difference between a quick outpatient procedure and a much more involved treatment further down the line.
Basal cell carcinoma starts in the basal cells at the base of the skin's outer layer (the epidermis), most often on skin that gets a lot of sun exposure: the face, ears, neck, scalp, shoulders and back. It's classed as a non-melanoma skin cancer, and while that sounds reassuring, it still needs medical attention. Left untreated, a BCC can grow into surrounding skin and, in rare cases, deeper tissue and bone, even though it almost never spreads to other organs the way melanoma can.
Basal cell carcinoma is also the most frequently occurring cancer of any kind in the UK. Around 100,000 people are diagnosed with non-melanoma skin cancer each year, and the lifetime risk for BCC specifically is estimated at 33–39% for men and 23–28% for women in the white population, with men affected roughly twice as often as women. Rates have been rising year on year, driven largely by cumulative sun exposure and an ageing population.
BCC can look different from person to person, which is part of why it's so often mistaken for a stubborn spot, a scar, or dry skin. Common presentations include:
Most basal cell carcinomas are painless, though some can itch or bleed intermittently. The single biggest clue is persistence: unlike a spot or minor injury, a BCC will not fully heal on its own. If a mark on your skin has been present for more than a few weeks, particularly if it keeps scabbing and reopening, it's a reason to get it looked at rather than wait and see.
The primary driver of basal cell carcinoma is cumulative ultraviolet (UV) exposure over a lifetime, whether from the sun or sunbeds. Other recognised risk factors include fair skin that burns easily, a history of sunburn (especially in childhood), older age, a weakened immune system, and previous radiotherapy. Because damage builds up over decades, BCC often appears in people in their 50s, 60s and beyond, though it can occur earlier in those with significant sun exposure or genetic predisposition.
This is exactly why sun protection earlier in life matters so much for reducing skin cancer risk overall, and why regular skin checks become more important as we age.
If your GP suspects basal cell carcinoma, you'll typically be referred to a dermatologist for assessment. Many suspected skin cancers are now managed under the Faster Diagnosis Standard, which aims to confirm or rule out cancer within 28 days of referral, replacing the older two-week-wait target. In practice, however, dermatology waiting lists in the UK remain under significant pressure: nearly 400,000 people are currently on dermatology waiting lists nationally, and average waits for a first appointment have more than doubled in some areas over the past decade.
Diagnosis usually involves a visual examination, sometimes with a dermatoscope, and often a biopsy, where a small sample of the lesion is removed under local anaesthetic and sent for testing. This confirms the diagnosis and subtype of BCC before treatment is planned.
The good news is that basal cell carcinoma is highly treatable, and outcomes are excellent when it's caught early. Standard NHS treatment options include:
For rarer, locally advanced cases, newer systemic treatments are also being trialled. NHS-backed research, including a phase 2 trial at Leeds Teaching Hospitals evaluating the drug cemiplimab, is investigating options for basal cell carcinomas that are too advanced for straightforward surgery. This reflects a broader shift towards more targeted treatment for the small proportion of cases that don't respond to first-line approaches.
The vast majority of basal cell carcinomas are cured with a single treatment, and BCC is very rarely fatal. That said, earlier treatment generally means a smaller procedure, less scarring, and a faster path back to normal life.
Basal cell carcinoma is common, highly treatable, and easiest to deal with when it's caught early — but getting a face-to-face dermatology appointment can take weeks or months on the NHS. If you've spotted a mark that won't heal, a pearly bump, or a patch of skin that's changed, don't sit on it while you wait for a referral to come through.
