  2. The Radiology of Malignant Neoplasms Malignant Tending to become progressively worse, and resulting in death

  3. The Radiology of Malignant Neoplasms Carcinoma Sarcoma

  4. The Radiology of Malignant Neoplasms Carcinoma A malignant neoplasm made up of epithelial cells.

  5. The Radiology of Malignant Neoplasms Sarcoma A malignant neoplasm usually arising from connective tissue cells, but some are of epithelial cell origin.
