2) Squamous Cell Carcinoma (SCC)
Squamous cell carcinoma (SCC) is the second most common type of skin cancer and is associated with chronic long term sun exposure. SCC can develop from pre-malignant skin lesions caused by long term sun exposure known as actinic keratoses which look like red scaling patches on the hands, face, and chest. SCC often has the appearance of a crusted sore (Figures 1 and 2) or firm red bump (Figure 3). The ears and lower lips are areas especially prone to develop SCC because of increased sun exposure. Unlike BCC, some SCC can grow rapidly and spread to lymph nodes if left untreated.
