Basal cell carcinoma is the most common type of skin cancer, affecting around 600,000-800,000 people in the US each year. It typically appears as a slow-growing, pale nodule on areas exposed to the sun, especially the head and neck region. While rarely metastatic, basal cell carcinoma can cause significant local tissue destruction if left untreated. Treatment options include surgical excision, Mohs micrographic surgery, cryotherapy, and radiation therapy, with the treatment approach depending on factors like tumor location and patient preferences.
