Ingesta de agua y cáncer vesical

Résumé

Globally, 19% of all cancers are attributable to the environment. The influence of environmental factors on the development of bladder cancer has been demonstrated. In the western countries, in the male is the 4th most frequent cancer and the 8th in women. In this study, we will try to demonstrate how the amount of water ingested and its type (tape water, mineral water, or well water) influence the development of bladder cancer (CV). To do this, we performed an observational and retrospective epidemiological study, case-control: 500 cases (diagnosis of previous CV) and 500 controls, inhabitants of the province of Cádiz, controls matched in age and sex to the cases. From the original study, much more extensive we extract the results obtained for a certain factor: WATER ingested. The relative exposure of each group to that variable or factor is compared. We analyzed its influence statistically according to the amount and type of water ingested in the development of this disease. In view of the results, we believe that by increasing the volume of fluids ingested and the frequency of micturition we decrease the time of exposure of carcinogens present in the urine over the urothelium. Regarding the type of water, well water intake seems problematic, although more studies are needed. We conclude that: consumption below 1 liter is a risk factor and above 2 liters is a protective factor
