Answer to Question 1

1. Carcinomas: occur in epithelial tissues and metastasize through the circulatory or lymphatic system and form solid tumors.
2. Sarcomas: occur in the mesodermal (middle) layer of tissue (bones, muscles, and connective tissue) and metastasize mainly through the blood. They also form solid tumors.
3. Lymphomas: occur in the infection-fighting regions of the body and metastasize through the lymphatic system. They also form solid tumors.
4. Leukemia: occurs in the blood-forming parts of the body (bone marrow and spleen) and is characterized by an abnormal increase in the white blood cells. This form is a nonsolid tumor.
