    VIAGRA and other impotence drugs help switch on the immune system to attack a range of cancers, a study has found.

    Here is a very interesting article about how Viagra ‘helps the body fight cancer’

    The disease usually manages to avoid destruction partly because tumours produce a fog of chemicals that hide it from white blood cells.

    But Viagra, a brand name for sildenafil citrate, and other such drugs were found to reduce the amount of these chemicals, enabling the immune system to target the cancer more effectively.

    Tests at the Johns Hopkins Kimmel Cancer Centre in the United States found the drug reduced the size of colon and breast tumours in mice threefold.

    In mice which were genetically engineered to lack an immune system, the tumours were unaffected, showing that Viagra was helping the body’s natural defence mechanisms fight the disease.

    Laboratory tests on human cancer cells showed similar results and clinical trials are planned for next year.
