The present title ‘Genetics of Cancer’ is the amazing advancement of molecular biology. It provides the various fundamental aspects of clinical and hereditary studies. The development of techniques for medical science is based on an understanding of the molecular aspect of hereditary processes occurring in human population. These techniques have, in turn, enabled expansion of our knowledge and understanding of how genes are organized and expressed in living cells and has provided major impetus to the development of immunological enterprises. It has been compilated for graduate and undergraduate students, research scholars, teachers, practising biochemical engineers, biotechnologists, applied and cell biologists and scientists involved in clinical research and development.
