Cancer Biology and Tumor Markers Quiz

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.
