According to a study, lifestyle factors are responsible for higher risk of melanoma, a deadly form of skin cancer in users of Viagra. The study, which analyzed medical records of more than 20,235 men, concluded that use of Viagra does not lead to melanoma.

It was also found in the study that the source of the observed increase in malignant melanoma risk among users of erectile dysfunction drugs is probably based on socioeconomic and lifestyle.

According to lead study author Stacy Loeb from New York University Langone Medical Center, proper use of such medications are very effective and also help improve the quality of life of several men. Loeb added that therefore men should know it is uncertain that these medications put them at greater risk of suffering from skin cancer.

According to Loeb, "What our study results show is that groups of men who are more likely to get malignant melanoma include those with higher disposable incomes and education -- men who likely can also afford more vacations in the sun”.

Between 2006 and 2012, a total of 4,065 were found to have malignant melanoma among over 20,000 men whose records were studied.

A total of 2,148 men had used any of the three main drugs for erectile dysfunction: Viagra, known as sildenafil, Levitra called vardenafil and Cialis known as tadalafil; some 435 out of them had the skin cancer. The complete study has been published in the Journal of the American Medical Association.
