Abstract
Historically, cancer is known to be a genetic disease. It is now realized that it
involves epigenetic abnormalities along with genetic alterations. Epigenetics is an
extra layer of instruction that lies upon DNA and controls how the genes are read
and expressed. It simply means changes in phenotype without a change in genotype.
In this review we aim to discuss the fundamentals of epigenetics, role of these alterations
in carcinogenesis and its implications for epigenetic therapies.
