Both arise from cells within the epidermis. They tend to grow more slowly and carry a lower risk of spreading compared to melanoma, but if left unaddressed they can gradually invade surrounding tissue, which is why early recognition matters. These lesions are especially common on areas with long-term sun exposure, such as the face, scalp, neck, and the backs of the hands. ### What does basal cell carcinoma typically look like? Basal cell carcinoma often appears as a shiny, pearly nodule, or as a lesion with a slightly raised border and a central area that looks sunken or ulcer-like. Small blood vessels may be visible on the surface, and the spot can feel like a wound that simply won't heal. Because it tends to grow slowly over months or even years, it's easy to mistake for an old acne scar or a minor injury. If a spot doesn't heal within a few weeks, or if it seems to be slowly changing in size, it's worth having a dermatologist take a look. ### How is squamous cell carcinoma different from basal cell carcinoma? Squamous cell carcinoma tends to present as a red, scaly patch or nodule with a rough, crusted surface. It often feels firm and uneven to the touch, and may ulcerate or bleed easily. It generally grows somewhat faster than basal cell carcinoma and has more of a tendency toward local invasion, so a lesion that visibly enlarges over a short period deserves prompt evaluation. It has also been reported to arise secondarily within chronic wounds, burn scars, or long-standing ulcers, so changes in those areas are worth watching closely. ### How can this be told apart from an ordinary mole or benign growth? Not every pigmented spot or raised bump signals skin cancer. That said, changes such as an existing mole or wart-like lesion becoming asymmetric, developing an irregular border, showing multiple shades of color, or growing beyond about 6mm in diameter warrant closer attention. The so-called ABCDE criteria (Asymmetry, Border irregularity, Color variation, Diameter, Evolving) are mainly used for melanoma screening, but the underlying idea of tracking a lesion's changes over time is also a useful reference point when BCC or SCC is suspected. Because it's genuinely difficult to distinguish benign from malignant lesions by sight alone, any suspicious spot should be evaluated by a dermatologist and, if needed, confirmed with a skin biopsy rather than judged on your own. ### Does removing a lesion mean it's completely resolved with no chance of recurrence? Treatment options — surgical excision, cryotherapy, topical medication, or photodynamic therapy — vary depending on the lesion's size, location, and histologic subtype, and the final approach is determined by a specialist based on biopsy results. Lesions caught and treated early generally tend to have a favorable outlook, but this doesn't mean recurrence or the development of new lesions is entirely ruled out, and outcomes vary by individual. People with a history of significant sun exposure or prior skin cancer treatment are generally advised to keep up with regular skin checks to monitor for new lesions. If you simply want a benign-looking mole or a cosmetically bothersome spot removed, it's safer to have its nature confirmed first through a [mole removal](/en/treatments/mole-removal) consultation rather than deciding on your own. ### How can this be prevented and managed day to day? Cumulative sun exposure is considered one of the main risk factors for both basal and squamous cell carcinoma. Applying sunscreen generously, reapplying as recommended, and combining it with physical protection like hats and long sleeves can all help. It's also useful to do a self-check of moles and skin lesions in front of a mirror about once a month, and to photograph anything that seems to be changing so you can compare it over time. Those with a family history or a weakened immune system are often advised to schedule dermatology checkups more frequently. This information is provided for general reference only.
