Aim: The aim of the review is to give information about the available immunotherapeutic approaches for the treatment of cancer.
Objective: This review aims to brief about the mechanisms and efficiency of various types of immunotherapies that manipulates immune response to treat tumours.
Background: In primary cancer treatment strategies like chemotherapy and radiation therapy, relapse of tumour is a significant problem. So, alternative therapies that harnesses the immune system are now the current trend to eliminate the tumour cells and may prove more efficient in the near future.
Reason: Since our understanding of the immune system has increased substantially, there are a variety of pathways that manipulate the immune system in different manners to promote anti-tumour responses. This review elaborates on the different immunotherapies and their mechanisms.
