Neoplasms are abnormal cells or tissues which have spread from their original location and become invasive (growing) in other parts of the body. They may be benign or malignant. The term neoplastic refers to any cell or tissue that has developed into another type than its normal one. For example, some types of cancer are called neoplasmas, while others are not neoplasms but rather tumors.
The word neoplasm comes from the Greek words neos meaning new and plasis meaning flesh. A neoplasm is a newly formed tissue or organ.
A neoplasm is different from a tumor because it does not require treatment with drugs to kill it; instead, it will die on its own. However, a tumor must be removed surgically if it is to be cured.
Types of Neoplasms:
Benign Neoplasms: These include the following: Acute myeloid leukemia (AML), Non-Hodgkin’s lymphoma (NHL), Myelofibrosis, Myositis, Pemphigus vulgaris, Polymyositis Complex and Pulmonary fibrosis.
