Our body consists of three types of blood cells - Red Blood Cells, White Blood Cells, and Platelets. The work of Red Blood Cells is to transport the oxygenated blood to all the parts of the body and deoxygenated blood back to the heart from rest all the parts of the body to the heart whereas the work of White Blood Cells is to protect the body from foreign cells. The third type of blood cell - Platelets helps in clotting the blood.
When a person suffers from cancer, it means that the number of white blood cells in the body is outranked by the cancerous cells and the body is unable to fight it. Best Oncologist in Jaipur at Candrol - Dr. Rishi Sharma, a treatment is required to restrengthen the white blood cells, so that they can fight and kill the cancer cells. The treatment of doing so is known as Immunotherapy.
Immunotherapy helps in restoring the health of the immune system and this can be achieved by:
Either blocking or slowing the growth of cancer cells.
Blocking the spread of cancerous to the other nearby organs i.e., to stop it from reaching the metastasis stage.
Supporting the immune system to perform better by strengthening it.
In chemotherapy, the drugs which are given to the body affects both cancerous as well as non-cancerous cells but in Immunotherapy, the drugs train the immune system in such a way that they affect and kill the cancerous cells. Another benefit which is associated with immunotherapy is that it is a non-conventional method of cancer treatment, which means that immunotherapy will cause a minimal number of side effects on the body as compared to the conventional methods of treatment like chemotherapy, radiation therapy, etc.
The different types of cancer immunotherapies are as follows:
1. Monoclonal Antibodies: Antibodies are a type of proteins which is produced by the Immune System. These antibodies get activated whenever the immune system detects something harmful in the body and fights against them.
2. Immune checkpoint inhibitors: The drugs used in Immune checkpoint inhibitors make the immune system recognize the cancer cells and attacks them accordingly.
3. Cancer vaccines: Vaccines are the substances which are injected into the body. Through the cancer vaccination, the body is made to recognize the presence of unhealthy/ cancerous cells in the body. There are mainly two types of cancer vaccines - prevention vaccines and treatment vaccines.
4. Other, non-specific immunotherapies: The main aim of these type of immunotherapies is to boost/ strengthen the immune system.
There are different types of immunotherapy which can be applied to you during the immunotherapy treatment of Cancer. In the present scenario, immunotherapy is one of the best treatment methods for cancer. Another advantage of immunotherapy is that it is a cost-effective treatment of cancer.
