Vocab Flashcards
Biotherapy
Modifies the biological processes that result in malignant cells primarily through enhancing the person’s own immune responses
Biotherapy is used for both hematologic malignancies, such as lymphoma and hairy cell leukemia and solid tumors such as renal cancer, lung cancer and melanoma.
Anaplasia
Regression of a cell to an immature or undifferentiated cell type.
Cell division is no longer under DNA control
Usually occurs when a damaging or transforming event takes place inside the dividing still undifferentiated cell leading to loss of useful function.
May occur in response to overwhelmingly distractive conditions inside the cell or in surrounding tissue
Bradytherapy
Internal radiation
Internal, interstitial or intracavitary radiation
Radiation is given inside the body by implanting small amounts of radioactive material directly into a tumor or body cavity while avoiding scattering radiation to the surrounding tissues or organs
This technique allows delivery of high doses of radiation to the tumor Ross bearing adjacent tissue
Cachexia
Characteristic feature of cancer. Wasted appearance of its victims.
Unexplained rapid weight loss is often the first manifestation that brings the patient to a healthcare provider.
This can be due to a variety of problems associated with cancer such as pain, infection, depression, or the side effects of chemotherapy and radiation.
Usually the emaciation, Malnutrition, and loss of energy are attributed to the anorexia cachexia syndrome (this syndrome is specific to cancer because of the effect of cancer cells on the hosts metabolism)
Cancer
Cancer is a group of complex diseases characterized by uncontrolled growth and spread of abnormal cells
Carcinogenesis
process by which normal cells are transformed into cancer cells.
Carcinogens
Certain agents that cause mutations in cellular DNA and transform cells into cancer cells
