Role of Genetics in Cancer Studies

Examiners have recognised that genetic association association of cancer studies are broad and complex, because of various stage processes of the cancer and the daunting issue of analysing genetic variants in family research and population. Researchers may now examine genetic variation and cancer. These studies have alot potential for uncovering many genetic risk factors which contribute to the complicated disease known as cancer, study design and interpretation methodologies must be carefully evaluated. If genetic variation is to realise the promise of personalised treatment, it must be replicated in sufficiently big, well-powered research. In this sense, the investigation of gene andgene and gene & environment interactions is the only way to ensure the plausibility of verified genetic variants.
