Cancer types (various)

Cancer types are classified based on where they originate in the body. For example, carcinomas develop in organs like the lungs, breast, or skin, and are the most common type. Sarcomas arise in connective tissues such as bones, muscles, or cartilage. Leukemias begin in blood-forming tissues like the bone marrow, leading to abnormal blood cell production. Lymphomas affect the lymphatic system, part of the immune response. Other types include brain tumors and tests for certain organs. Each type varies in growth rate, severity, and treatment approaches, making accurate diagnosis essential for effective management.
