Chemotherapy Cancer ,which is also called Malignant tumors ,it controll cell growth and proliferation mechanism disorder caused by the disease. also it will invade the surrounding normal tissues even through circulating system or the lymphatic system is transferred to the rest of your body. Now people more and more early to have cancer, Many things can let us more easy to increase the risk of cancer, there are including smoke, certain infections, radiation, lack of physical activity, obesity, and environmental pollutants.These can directly damage genes or combine with existing genetic faults within cells to cause the disease. Chemotherapy is one of the methods for the treatment of cancer. That uses drugs to destroy cancer cells. It is also called â€Å"chemo. † Today, there are many different kinds of chemotherapy. So the way patient feel during treatment may be very different from someone else. Why I chosen this treatment, because Chemotherapy is a common treatment that I usu ally heard in news or someone talk about it, so I also interested in this treatment.Chemotherapy can be used to: Destroy cancer cells,Stop cancer cells to spread ,Slow the growth of cancer cells. Chemotherapy can be given alone or with other treatments to cure. It also can help other treatments work better. For example, you may get chemotherapy before or after surgery or radiation therapy. Or you may get chemotherapy before a peripheral blood stem cell transplant. can be given in these forms: an IV (intravenously),a shot (injection) into a muscle or other part of your body,a pill or a liquid that you swallow, a cream that is rubbed on your skin.But chemotherapy have many disadvantage, this treatment will hurt your body and let your body become weak. Because chemotherapy have poor selectivity on cancer cells, it have a toxic effect on the cancer cells and normal cells. Besides it can kill the cancer cells, at the same time it is obvious damage the organ function and normal tissue cel ls. Chemotherapy common side effects: 1) Myelosuppression: Most chemotherapy drugs can cause Myelosuppression , and it shows for the decline in white blood cells and platelets, fraudulent claims red fine chest, even like hemoglobin decreased. 2) gastrointestinal reactionLoss of appetite, eating less,feel sick, vomiting, abdominal distension, abdominal pain, diarrhea or constipation. 3) Cardiac toxicity Some chemotherapy drugs can produce cardiac toxicity, damage to myocardial cells, palpitation, palpitations, chest tightness, precordial discomfort, shortness of breath and other symptoms, even it will heart failure. 4) liver damage Patients with liver discomfort, and even can cause toxic hepatitis. 5) kidney damage Cause renal dysfunction and low back pain, kidney discomfort. 6) Phlebophlogosis The vascular lesions Color become dark red or dark yellow, localized pain. ) Toxicity of the nervous system Mainly refers to the chemotherapy drugs produce damaging effects on the surrounding nerve endings, the patient may appear extremities numb extremities sensation. 8) Anaphylaxis Many cytotoxic drugs will cause varying degrees of allergy. I think’s disadvantage was more than advantage, and this treatment will hurt our body, in my opinion for patients who has poor health, poor liver and kidney function, low white blood cells, and malnutrition, in addition to rescue type chemotherapy. I don’t think chemtherapy was a good idea to treat cancer.And people who has Terminal cancer do not use the way of Chemotherapy, maybe you don’t do anything can let you stay in world for more time. Chemotherapy will make you miserable. So health is precious! We have to keep our body more and more health, stay away from cancer. http://wenku. baidu. com/view/faecdb80d0d233d4b14e6985. html http://wenku. baidu. com/view/a33d7a65caaedd3383c4d3c6. html http://www. cancer. gov/cancertopics/types/alphalist http://translate. google. com. hk/translate? act=url&hl=zh-CN&ie=UTF8& prev=_t&sl=en&tl=zh-CN&u=http://www. cancer. gov/cancertopics/types/alphalist
