CANCER OCCURS when cell division gets out of control
... While no two cancers are genetically identical (even in the same tissue type), there are relatively few ways in which normal cell growth can go wrong. One of these is to make a gene that stimulates cell growth hyperactive; this altered gene is known as an 'oncogene'. Ras is one such oncogene product ...

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
