The periodic statistic defines encyclopaedically, urothelial bladder melanoma ranks the fifth most common cancer in men and the fifteenth in women, and the prevalence rate increases in people aged than 60 (1). Oncologists and pathologists in Egypt have suggested that Egypt has one of the loftiest prevalence rates of bladder cancer among men in the world, estimated prevalence rate of37.7 cases per 100,000 males (2). The histopathological profile of bladder cancer has changed significantly over the once 26 times. Historically, scaled cell melanoma but now a days, transitional cell melanoma has come the most frequent type and this shows the change in the epidemiology of the complaint (3). Individual variation in the inheritable constitution of humans may affect the host responses to constant assaults from exogenous and endogenous carcinogens, which will ultimately impact cancer threat, complaint prognostic and clinical outgrowth. Then we're agitating about a number of associations and limitations of current inheritable vulnerability exploration and suggest unborn directions in molecular epidemiology study. DNA polymorphism, a condition in which one of two different but normal nucleotide sequences can live at a particular point in DNA, the appearance of heritable mutation in a population at high frequency. Since heritable mutations eventually lead to elaboration, hence study of DNA polymorphism is important from the evolutionary perspective for the progression of bladder cancer. Different alleles of a gene produce different phenotypes which can be detected by making crosses between parents with different alleles of two or further genes. Also, by determining recombinants in the get, a inheritable chart can be derived. DNA polymorphisms constitute molecularly defined differences between individual mortal beings; hence the dominant homozygous, heterozygous and sheepish homozygous alleles can be helpful for the identification of heritable bladder cancer normal, carrier and diseased independently. The present study aimed to find out the association of polymorphic variations in the glutathione S transferase gene (GSTP1) with the bladder cancer in an Eastern Indian Population. From worldwide and civil studies, it was hypothecated that the GSTP1 gene polymorphism is a common event in people suffering from bladder cancer. It was hypothecated that the PCR-RFLP fashion is a good and robust fashion for discovery of this polymorphism. Consequently, the present study was designed and executed.
