Immunotherapy: The Future Treatment for Cancer

Immunotherapy: The Future Treatment for Cancer

The treatment of cancer is associated mainly with surgery & various kinds of therapy like chemotherapy, radiation therapy, biological therapy, hormone therapy etc. Surgery is widely used in the removal of tumor.  Tissues surrounding the tumor & the lymph nodes are removed through surgery. Rays of very high energy are used in radiation therapy. These rays are used to destroy the cancer cells & also to stop the growth of the cells. The treatment of cancer with the help of medicines is called chemotherapy. These medicines are injected into the veins or muscle of the patients. The injected medicine flows through the blood to the almost every part of the body & damage the cancer cells. Several types of cancer like prostate cancer or breast cancer rely on hormones for their growth. As a result, many hormone therapies are recommended by the physicians so that the cancer cells can’t get the hormone they needed. Biological therapies are also called immunotherapy. Immunotherapy uses the own immune system of the body for fighting against infection. Monoclonal antibodies, interleukin-2, interferon, various kinds of colony stimulating factor like G-CSF, GM-CSF etc. are used as biological therapy.  In a recent study, it has been found that the immune cells of the healthy individuals may be a very good immune care of cancer. This treatment can destroy the cancer cells without destroying the neighbouring cells. The vaccines are designed mainly based on the stimulation of the defense system of the patient for invading the tumor cells. But, for achieving an effective treatment, the immune system should react very strongly. But, this task is very difficult for the immune system of the patient. Instead of using the patient’s weak immune system, if the vaccines can use the stronger immune response of a healthy people, then it is possible to treat the cancer cells more effectively. It hopes us for the eradication of cancer forever.
