Cancer immunotherapy using the patient's immune system to fight cancer. This is achieved in two different ways: active and passive treatments. Last treatment seeks to stimulate the immune system of the patient for the system to attack cancer, usually through the delivery of vaccines. Immune negative cancer does not depend on the body to respond to the cancer, but offers from man-made tools for the body to fight the disease. These tools are usually antibodies.People with weakened immune systems are more susceptible to cancer. This does not mean that someone has a healthy immune system can not succumb to cancer, but the rate is much higher if the risk of severe health. Attempts at immunotherapy for cancer of the immune system to give the patient the tools or training, as is the case with vaccines, to battle cancer. Tumors produce many antibiotics. Antigens are proteins that the body considers dangerous. Sometimes antigens do not differ enough from the cells around the tumor, the however.The also often not classified tumors and foreign. Immune attacks, aggressive and, therefore, against the tumor rarely occurs. And increases the complexity of the situation because the small environment surrounding the tumor immunity, making it difficult for the immune system to attack cancer.Vaccines can stimulate the immune system to recognize cancer and foreign. Vaccine antigen to try to get the body to produce antibodies that will try to neutralize the cancer cells. Vaccines can decrease immune Also, change the cancer cells so that they are more vulnerable to attack by the immune system, or improve the body's response to chemotherapy. It can also be used as vaccines as a preventive measure.
