Study Notes

Cancer Classification

  • Sarcomas arise from cells found in the supporting tissues of the body, such as bone, cartilage, and fat.
  • The prefix 'osteo' signifies "bone" in naming cancers.
  • Carcinomas typically arise from epithelial cells, which cover the body's internal and external surfaces, including the skin, lung, breast, colon, and prostate.
  • Leukemias are characterized by uncontrolled growth of abnormal white blood cells in the bone marrow and blood.

Cancer Characteristics

  • The most common type of cancer is carcinoma, which accounts for about 85% of all cancers.
  • Carcinomas are distinguished from other types of cancer by their origin from epithelial cells, which form the lining of glands, ducts, and other body surfaces.
  • Sarcomas are distinguished from other types of cancer by their origin from connective tissue cells, such as bone, cartilage, and fat cells.
  • Lymphomas are distinguished from other types of cancer by their origin from immune cells called lymphocytes in lymphoid tissues, such as lymph nodes, spleen, and lymphoid tissues.
  • Leukemias are distinguished from other types of cancer by their origin from blood-forming cells in the bone marrow.

Cancer Nomenclature

  • Technical names for different types of carcinomas, sarcomas, lymphomas, and leukemias are created by combining the root of the affected tissue or organ with the suffix '-carcinoma', '-sarcoma', '-lymphoma', or '-leukemia', respectively.
