Cancer can arise from various tissue types, resulting in different histological classifications. The most common ones include:
Carcinomas: Cancers originating from epithelial cells, which line the surfaces of organs and structures. Examples include adenocarcinoma and squamous cell carcinoma. Sarcomas: Arising from connective tissues like bone, cartilage, and muscle. Lymphomas: Originating from the lymphatic system. Leukemias: Cancers of the blood-forming tissues, primarily affecting white blood cells.
