Basal cell carcinoma is the most common type of skin cancer, originating in the basal cells of the epidermis, the outermost layer of skin. It typically develops in areas frequently exposed to the sun, such as the face, neck, and arms. BCC grows slowly and rarely metastasizes to other parts of the body, but if left untreated, it can cause significant local tissue damage. It is present as a pearly or waxy bump, often with visible blood vessels. It may algo appear as a flat, scaly patch, sometimes with a rolled border. Risk factors include prolonged UV exposure, fair skin a history of sunburns, and weakened immune system. Treatment options include surgical excision, Mohs surgery, topical therapies, radiation, depending on the size, depth, and location of the tumor. Prevention involves regular sun protection, such as using sunscreen and avoiding excessive sun exposure
