Abstract

Cancer is designated as unhindered cell growth. Gene mutations can initiatemalignancy by increasing the rate of cell division or preventing usual controls on the system, like cell cycle arrest or apoptosis. As per earlier established studies, it is well known that the primary cause of cancer is some unwanted changes in the structure of DNA that are else considered as mutations. Mutations causing cancer can be due to a number of reasons including the lack of fidelity of the DNA replication machinery, disclosures to the mutagen, enzymatic DNA alteration, and faulty repair of DNA that consequences a certain fingerprint on DNA damage. Every living cell of the human body retains somatic mutations all through life.
