Recent technical advances in this field will give rise to conceptual advances and there is every reason to believe that a new field of cancer genetics is emerging, named here Oncogenetics: a branch of genetics describing the cause of effects of genes causing neoplasia.
Epigenetics, the study of the chemical modification of specific genes or gene-associated proteins of an organism. Epigenetic modifications can define how the information in genes is expressed and used by cells.
