Can HPV itself cause penile cancer? I generally keep my penile area clean (no smegma) and also tale immune boosters. Whats my penile cancer risk?

Yes. Risk of penile cancer is less than one in 100,000 men. HPV is found in 50% of cases. Men who have a history of HPV DO have a higher risk of cancer than the population. Check out more stats here... http://www.cdc.gov/cancer/hpv/statistics/cases.htm.
