Final answer:
Basal cell carcinoma is the skin cancer characterized by pearly nodules, and is commonly treated with surgical methods.
Step-by-step explanation:
Basal Cell Carcinoma
The type of skin cancer characterized by pearly nodules is basal cell carcinoma. Basal cell carcinoma originates from the basal cells, which are a type of stem cell found in the deepest layer of the epidermis. This form of cancer is identified by the presence of lesions that may appear as waxy or pearly bumps on the skin, often with a central depression and visible blood vessels. Most common in areas exposed to the sun, such as the head and neck, this carcinoma is the most frequent skin cancer in the United States, with over four million cases each year. Although basal cell carcinomas rarely metastasize, early diagnosis and treatment are crucial for a good prognosis. Treatment options often include surgical excision or biopsy, cryosurgery, and topical medications.
