Impact the Influence of Immunotherapy on Cancer

Immunotherapy is a treatment that uses certain parts of a person’s immune system to fight diseases such as cancer, when the immune response is not strong enough to recognize cancer cells or signals are produced by cancer cells that make the immune system unable to attack them or the cancer cells escape from the immune system. Immunotherapy helps the immune system to destroy cancer. Immunotherapy can be useful for a few types of cancer, but it is not suitable for all types of cancers. Immunotherapy can be used on its own(alone), or in combination with other treatments such as chemotherapy, surgery, or radiotherapy. This review article emphasizes the pivotal role that advancements in cancer immunotherapy's history have played in establishing treatments that are now considered standard of care and delineates several primary strategies employed in the field of cancer immunotherapy (cancer vaccines, adoptive cellular immunotherapy, immune checkpoint blockade, and oncolytic viruses, Immunomodulators).
