Oncoimmunology or Immunoncology- Is the Concept of Immunotherapy Applied Globally in Cancer?

Cancer has for long been classified as having an origin in a type of cell or tissue and has for ages been considered as a result of a single tumor cell. With the advances in genomics, transcriptomic and epigenetic research, cancer has now been recognized as a heterogeneous disease within itself. This enables clonal survival and resistance to therapies. However, cancer and inflammation have walked side by side for decades. The real knowledge of its interactions between the immunological system and carcinogenesis is yet to be wholly understood. Much has been discovered on how these interactions occur, how they differ in an intratumoral context and with the direct influence of the microenvironment.
