A spot that repeatedly bleeds when you towel-dry your face is not something to keep watching. Neither is a tiny sore that seems to heal, then returns in exactly the same place. Basal cell carcinoma symptoms are often subtle at first, which is why this common skin cancer can be mistaken for a pimple, dry skin, a harmless scab or a minor injury.
Basal cell carcinoma, often called BCC, is the most common type of skin cancer in Australia. It usually grows slowly and rarely spreads to distant parts of the body. That does not make it harmless. Left untreated, a BCC can grow deeper into the skin and damage nearby tissue, particularly on the nose, ears, eyelids, lips and scalp. Early assessment usually means simpler treatment and a better cosmetic outcome.
What does basal cell carcinoma look like?
BCC does not have one fixed appearance. Its look depends on the subtype, its location and a person’s skin tone. The key warning sign is persistence: a spot that does not properly heal, continues changing, or repeatedly breaks down deserves a clinical assessment.
A common presentation is a small, shiny or pearly lump. It may be skin-coloured, pink, red or slightly translucent, with fine blood vessels visible across the surface. On darker skin, it can appear brown, black, bluish or simply darker than the surrounding skin, rather than pearly pink.
Some BCCs look like a sore. They may form a crust, ooze, bleed after minor contact or develop a shallow central dip. The skin around it may look raised or rolled. A lesion that appears to heal but returns is particularly concerning, especially if it has been present for several weeks.
Superficial BCC can look more like eczema or a patch of dermatitis: a persistent red, pink or brown scaly area, often with a slightly raised edge. It commonly develops on the trunk, shoulders, chest or back. Moisturiser may soften the scale temporarily, but it does not resolve the underlying lesion.
A less obvious form can resemble a pale, waxy or scar-like patch without a clear border. This type may feel firm or tight and can be missed because it does not always bleed or crust.
Basal cell carcinoma symptoms that need a skin check
Book a skin check promptly if you notice a spot that persists beyond a few weeks, grows slowly, changes in shape or colour, or behaves differently from the skin around it. The following signs are especially worth acting on:
- a pearly, shiny, pink, red, brown or dark bump that enlarges over time
- a sore, scab or ulcer that does not heal, or heals and returns
- repeated bleeding, weeping or crusting without a clear cause
- a rough, scaly patch that remains despite appropriate skin care
- a pale, firm, scar-like area where there has been no injury
- a new or changing lesion on a sun-exposed area, particularly the face, ears, neck, scalp, shoulders or lower legs
Itching, tenderness or soreness can occur, but many BCCs cause no pain at all. Waiting for pain is not a safe way to judge whether a spot needs attention.
The difference between a BCC and a pimple
A pimple usually follows a short cycle: it appears, settles and clears. A BCC tends to persist. It may be small for months, but it does not fully disappear. It can also bleed with little provocation, such as shaving, washing your face or rubbing it with a towel.
That said, skin cancers cannot be reliably diagnosed by appearance alone. A pimple, benign growth, eczema, actinic keratosis, squamous cell carcinoma and melanoma can overlap in appearance. A GP with skin cancer expertise or a skin cancer doctor can examine the lesion using dermoscopy and decide whether a biopsy is needed.
Where BCC is most likely to appear
Most basal cell carcinomas arise on areas that receive frequent ultraviolet (UV) exposure. In Australia, that often means the face, nose, ears, neck, scalp, chest, shoulders, forearms and lower legs. They can also occur in less exposed places, so a changing spot anywhere on the body should not be ignored.
The scalp deserves particular attention for people with thinning hair, baldness or a history of outdoor work. It is easy to overlook during self-checks. Ask a partner, family member or hairdresser to mention any new sore, crusted area or changing patch they notice, but arrange a clinical check rather than relying on a casual opinion.
BCC can occur on the eyelids and around the eyes, where delays can be more consequential because of the delicate surrounding structures. A persistent lump, lash loss, recurring sore or non-healing area near the eye should be assessed without delay.
Who has a higher risk?
Anyone can develop BCC, including people with skin of colour. Risk is higher in people who have had substantial cumulative UV exposure, frequent sunburns, fair skin that burns easily, many years of outdoor work or recreation, or a personal history of skin cancer.
Age increases risk because UV damage accumulates over time, but BCC is not only a concern for older Australians. People who work on building sites, farms, roads, in transport, on the water or in other outdoor settings may have significant exposure earlier in adulthood. Regular skin checks are a practical part of protecting your health, just like using sun protection on the job.
Risk can also be increased by immune suppression, previous radiation treatment, certain genetic conditions and a family history of skin cancer. If you have had a BCC before, you are more likely to develop another one. Your clinician can advise how often you should have full-skin examinations.
When should you seek medical advice?
Make an appointment soon for any suspicious lesion, particularly one that has lasted longer than four weeks or is bleeding, ulcerated, growing or changing. Do not try to remove it yourself, burn it off, or repeatedly treat it with over-the-counter wart, acne or eczema products. These can irritate the skin and delay a diagnosis.
Seek more urgent medical advice if a lesion is rapidly enlarging, painful, infected-looking, close to the eye, on the lip or ear, or causing functional problems such as difficulty closing an eyelid. While BCC is usually slow-growing, the location and subtype affect how quickly treatment should happen.
A skin check is generally straightforward. The clinician will ask about how long the spot has been present and whether it has changed, then inspect it closely. If it looks suspicious, they may take a small biopsy or discuss removal. Treatment can include surgical excision, curettage and cautery, cryotherapy, topical medicines, photodynamic therapy or specialised surgery for high-risk areas. The right option depends on the type, size, depth and location of the cancer.
Checking your own skin between appointments
Self-checks are useful, but they are not a replacement for professional examination. Once a month, use a mirror in good light to check your face, ears, neck, chest, arms, hands, legs and feet. Use a hand mirror for your back, buttocks and the backs of your legs, or ask someone you trust to help.
Take note of anything new, changing or persistently sore. A dated photo can help you track a lesion over a few weeks, but it should never be used as a reason to postpone an appointment when a spot is suspicious. Skin cancer can be difficult to judge from photos, and a lesion may look less concerning on a mobile screen than it does under dermoscopy.
Prevention still matters after years of sun exposure. Use broad-spectrum SPF 50+ sunscreen, protective clothing, a broad-brimmed hat, sunglasses and shade whenever UV levels call for protection. Avoid deliberate tanning and do not use solariums. These steps reduce further UV damage, although they cannot reverse damage already done.
A non-healing spot is not something you need to diagnose at home. Acting early is the practical choice: arrange a skin check, get a clear answer and give treatment the best chance to be simple and effective. Knowledge can save your life.
