Many tumors cause chronic inflammations, which, in their turn, suppress specific attacks against the tumor by the immune system. Scientists at the German Cancer Research Center and Medical Faculty Mannheim at Heidelberg University have now shown in mice with melanoma that sildenafil - the active ingredient in Viagra - cancels the suppression of the specific immune response. Cancerous mice treated with the drug survived more than twice as long as untreated fellow animals.
