Explanation:

• Carcinoma is a type of cancer that begins in the skin or in tissues that line or cover internal or outer surfaces. It can come from various epithelial cells (not just specialized skin cells). Lung cancer and breast cancer are commonly classified as carcinomas. Carcinomas are the most common form of cancer. Metastasis is the spread of cancer cells (not the same as carcinoma). Cancer cells (including carcinomas) do not practice contact inhibition (normal cells stop growing when they come into contact with other cells; cancer cells don't).
