Write 9 pages thesis on the topic common assessment topics. For decades now, radiotherapy, chemotherapy, and surgery have been the only effective methods of treating cancers. However, these methods fail to eliminate cancerous cells in some patients. Such patients may be helped by gene therapy, a new and promising way of treating cancer. Gene therapy is the insertion of a foreign functional gene into specific cells of a patient to repair an acquired mutation, correct an inborn metabolic error, or provide a cell with a new function. The understanding of cancer at the molecular level has improved tremendously. Among the promising approaches to emerge in this area is the possibility of utilizing gene therapy to target and destroy selective tumor cells. This can be achieved by using this technique to correct an abnormality in tumor suppressor genes, especially P53, and prevent overexpression of oncogenes such as K-RAS, which has been established to be a characteristic of various malignancies.
