The accumulation of DNA mutations and epigenetic variations that leads to uncontrolled cell proliferation and formation of neoplasm refers to cancer. It is a genetic disease. The sub branch of genomics that deals with the study of cancer related genes is known as oncogenomics. The primary goal of the discipline is to recognize new tumor suppressor genes and oncogenes that may lead to new insights in the diagnosis of cancer, help predict the clinical outcome of different cancers and identify new targets for cancer therapies. It uses the techniques of transciptomes, genome sequencing, bioinformatics, functional analysis of oncogenes, etc. The field is also concerned with personalizing cancer treatment by identifying and targeting mutations in an individual patient. The book elucidates the concepts and innovative models around the prospective developments with respect to oncogenomics. The various studies that are constantly contributing towards advancing technologies and evolution of this
