| adjuvant therapy | assisting primary treatment |
| anaplasia | loss of differentiation of cells;reversion to a more primitive cell type |
| angiogenesis | process of forming new blood vessel |
| antibiotics | chemical substance, produced by bacteria or primitive plants. They inhibit the growth of cell and are used in cancer chemotherapy |
| apoptosis | programmed cell death. normal cell undergo apoptosis when damaged or aging. Some cancer cells have lost the ability to undergo apoptosis and they live foever |
| benign tumor | noncancerous growth |
| carcinogens | agents that cause cancer, chemicals and drugs, radiation and viruses |
| carcinoma | cancerous tumor made up of cells of epithelial origin |
| viral oncogens | pieces of DNA that when broken down or dislocated can cause a normal cell to become malignant |
| chemotherapy | treatment with drugs |
| dedifferentiation | loss of differentiation of cells; reversion to a more primitive, embryonic cell type; anaplaia or undifferentiation. |
| deoxyribonucleic acid | genetic material within the nucleus of a cell; controls cell division and protein synthesis |
| differentiation | specialization of cells; unspecialized cells are modified and altered to form specific and characteristic types and functions |
| encapsulated | surrounded by a capsule; benign tumors are encapsulated |
| infiltrative | extending beyond normal tissue bounderies |
| invasive | having the ability to enter and destroy surrounding tissue |
| irradiation | exposure to any form of radiant energy such as light, heat, or x-rays |
| malignant tumor | tending to become worse and result in death; having the characteristics of invasive, anaplasia, metastasis |
| metastatsis | spread of malignant tumor to a secondary site |
| mutation | change in the genetic material (DNA) of a cell; may be caused by chemicals or viruses or may occur spontaneously |
| neoplasm | new growth benign or malignant tumor |
