Therefore, drawing on a variety of sources the paper will discuss pharmacogenetics in cancer.

Cancer is a very unusual disease because it emanates from the accumulation of several gene mutations within the cell, thus disrupting normal cellular function as well as normal checks. Therefore, cancer cells have definite genetic profiles. As result, pharmacogenetics is helpful as a cancer therapeutic since is focuses on the genetic profiles and a person’s interaction with the drug. Pharmacogenetics can be described as the interaction between the drug and individual traits, and is very helpful in cancer therapeutics. Therefore, it is based on the clinical efficacy observations as well as tolerability profile of a drug in a person (Licinio and Wong 129). The most common challenge in cancer treatment is the related to the anticancer drugs. The pharmacogenetics can assist in the discovery, development, and individualization of the anticancer drugs.
