FAQs
What are the key visual differences between basal cell carcinoma and a benign mole?
Basal cell carcinoma usually appears as a small, pearly or translucent bump with a raised, sometimes ulcerated edge, while a benign mole is typically flat or uniformly raised, evenly colored, and has well‑defined borders.
How can I use the ABCDE rule to spot melanoma in pictures?
Look for Asymmetry, Border irregularities, Color variation, Diameter larger than 6 mm, and Evolving changes. Any lesion that shows several of these signs in a photo should be evaluated by a dermatologist.
When should I be concerned about a scaly skin patch that looks like squamous cell carcinoma?
If the patch is thick, crusty, bleeds easily, or keeps growing despite normal care, it warrants prompt medical attention, as these are typical warning signs of SCC.
Are mobile skin‑cancer apps reliable for self‑screening?
Apps can help track changes over time, but they are not diagnostic tools. Use them as a diary, not a substitute for a professional skin exam.
How often should I perform a full‑body skin check?
Conduct a thorough self‑exam at least once a month, and increase frequency after intense sun exposure or if you notice any new or changing lesions.
