DEVELOPING TREATMENT FOR CANCER

Do you know what is the most probable cause of death in Korea? It is cancer. However, many types of carcinostatic agents have developed over the years. There are three kinds of the carcinostatic drugs: chemical drug, target drug, immune drug. The problem of the chemical drug is that it attacks not only cancer cells but also normal cells. It causes many side effects such as hair loss or anemia. The target drug was studied to overcome this problem. It attacks only cancer cells. The target drug can discern what is the cancer cell or the normal cell by recognizing specific genes or proteins. For instance, a gene called BRCA that causes the breast cancer can be the target. However, sometimes these specific substances live in the normal cells. It results in the side effects. To be specific, there is Herceptin which attacks HER2. The problem is that HER2 is found not only in the cancer cell but also in the normal cell. For this reason, the side effect associated with a heart can occur. Furthermore, the cancer cell can come up with a new way to survive, when the target drug is prescribed. The immune drug is differentiated from the chemical agent and the target drug in the light of the fact that it does not attack the cancer cells directly. It attacks the cancer cells by using immune cells. It is hard for the immune cells to discern the cancer cells are enemies or not because the cancer cells apply immune escape strategy. However, the immune drug attacks immune escape substances. Therefore, immune cells can recognize that the cancer cells are enemies. Immune cells begin to attack the cancer cells. It can prevent the growth of the cancer cells. The advantage of the immune drug is that there are almost no side effects. Recently, the immune drug shows good results at the treating of lung cancer.
