It  is the sub field of the genomics which is characterise with the genes associated with cancer along with the main focus on the epigenetics, alterations in transcripts, genomics in cancer.  Even cancer can cause genetically due to random compilation of the mutated genetic materials and alteration of genetic material epigenetically which results in the formation of the neoplasm along with the proliferation of the unrestrained cells.

The main focus of this, is in the identification of the alternate oncogene or any tumor suppresser gene which will be helpful in the cancer diagnosis, in therapies and as well as predicting the clinical results thus may lead to increase in the treatment. There are various therapies in cancer which gave hope in the production new product in treating cancer like Avastin, Gleevec and Herceptin.
