Viagra could lower the risk of colorectal cancer

A small dose of Viagra taken daily significantly reduced the risk of colorectal cancer in guinea pigs that had a genetic predisposition for this form of cancer, the third leading cause of global mortality, according to recent studies. Darren D. Browning, a researcher at the Georgia Cancer Center and Department of Biochemistry and Molecular Biology at the Medical College of Georgia at Augusta University and study co-ordinator. When they added Viagra to drinking water, researchers found that the number of polyps in mice with the same genetic mutations that occur in people at risk of colorectal cancer, mutations that trigger the appearance of hundreds of polyps since adolescence and that turns out . A small dose of Viagra administered daily can reduce the number of cancerous tumors by half. Viagra is recognized for its ability to relax blood vessels, making it easier to fill with blood, which helps in erectile dysfunction as well as in pulmonary hypertension.

But studies in Browning's laboratory show that it also increases the level of chemically cyclic GMP, which is known to affect the intestinal mucosa called epithelium. While details of how this happens, Browning and his team have seen that increased cyclic GMP results include suppressing some of the excessive cellular proliferation that occurs in the gut and an increase in normal cell differentiation as well as natural elimination .
