Cancer immunotherapy involves using components of the immune system to fight cancer cells. The immune system is very effective in getting rid of pathogens such as bacteria and viruses. The concept of unleashing the body’s ability to defend itself against cancer cells has long been a scientific discussion (Nathanson L. 1976). Over the last 10 years, scientists have synthesized drugs that block pathways to keep cancer cells into evading the immune system. Several immune based therapies such as monoclonal antibodies, T-CARS and checkpoint inhibitors and therapeutic vaccines are available and analyze to fight cancer. So, it now appears that cancer immunotherapy hold great promises in helping cancer patients which first seemed unresponsive to standard treatments such as radiation and chemotherapy. While the field has attracted a lot of attention many drugs and therapies are still undergoing clinical trials, thus contain many gray areas. It is still unknown why cancer immunotherapy works for some but not all patients. In this review, I will discuss current therapeutic approaches in cancer immunotherapy. The paper begins with a brief overview of what cancer immunotherapy is and root of the field, before delving into how various parts of the immune system allow it to attack tumors. I then outline studies that show the immune system is capable to attack cancer cells.…
