Cancer can be classified into various types based on their histological appearance:
Carcinomas: These cancers arise from epithelial cells and are the most common type. They include adenocarcinomas (glandular origin) and squamous cell carcinomas (squamous epithelium). Sarcomas: These cancers originate from connective tissues such as bone, muscle, and fat. Leukemias and Lymphomas: These cancers affect the blood and lymphatic systems, respectively, and are characterized by abnormal proliferation of white blood cells. Neuroendocrine Tumors: These arise from cells of the neuroendocrine system and can have varied behaviors and histological appearances.
