Viagra (sildenafil) has been used successfully to treat erectile dysfunction in men since the 1990s, and these blue pills are still popular today, according to Pannochka, an online publication for girls and women aged 14 to 35.. net But recently, scientists from the University of Tubingen in Germany warned that sildenafil is able to stimulate the growth of melanoma cells.

Viagra belongs to a group of drugs called phosphodiesterase type 5 (PDE-5) inhibitors.

The drugs in this group dilate the blood vessels of the penis, contributing to stronger and longer erections..

Professor Robert Feil in his article on the pages of Cell Reports writes that PDE-5 affects the signaling molecule cyclic guanosine monophosphate (cGMP), which in turn plays an important role in metabolism, the work of blood vessels, heart, sensory cells. The action of cGMP is not fully understood, and now German scientists have discovered that harmless pills can spur the growth of malignant cells..

" By depriving cells of this natural inhibitor, sildenafil allows cancer to grow much faster..

This mechanism may explain why men who take Viagra are more likely to be diagnosed with skin cancer, "

Professor Feil points out that patients with melanoma should definitely consult with their doctor whether to take sildenafil in the light of new scientific evidence.. For the rest of the men who use this drug, the scientist recommends protecting themselves from the scorching sun and not visiting solariums..

The professor also expressed the opinion that other PDE-5 inhibitors have the same properties..
