circumcision penile cancer risk refuted

That is right faulty methods in research have been discovered and it has been found that being intact does not increase your risk of penile cancer.
Can Penile Cancer Be Prevented?
The large variations in penile cancer rates throughout the world strongly suggest that penile cancer is a preventable disease. The best way to reduce the risk of penile cancer is to avoid known risk factors whenever possible.
In the past, circumcision has been suggested as a way to prevent penile cancer. This suggestion was based on studies that reported much lower penile cancer rates among circumcised men than among uncircumcised men. However, most researchers now believe those studies were flawed because they failed to consider other factors that are now known to affect penile cancer risk.
For example, some recent studies suggest that circumcised men tend to have certain other lifestyle factors associated with lower penile cancer risk: they are less likely to have many sexual partners, less likely to smoke, and more likely to have better personal hygiene habits. Most public health researchers believe that the penile cancer risk among uncircumcised men without known risk factors living in the United States is extremely low. The current consensus of most experts is that circumcision should not be recommended as a prevention strategy for penile cancer.
Perhaps the most important factor in preventing penile cancer in uncircumcised men is good genital hygiene. Most public health experts recommend that uncircumcised men practice good genital hygiene by retracting the foreskin and cleaning the entire penis. If the foreskin is constricted and difficult to retract, a doctor may be able to cut the skin to make retraction easier.
Avoiding sexual practices likely to result in HPV infection might lower penile cancer risk. In addition, these practices are likely to have an even more significant impact on cervical cancer risk. Until recently, it was thought that the use of condoms ("rubbers") could prevent HPV infection. But recent research shows that condoms poorly protect against infection with HPV. This is because HPV can be passed from person to person by skin-to-skin contact with any HPV-infected area of the body, such as skin of the genital or anal area not covered by the condom. It is still important, though, to use condoms to protect against AIDS and other sexually transmitted diseases that are passed on through some body fluids.
The absence of visible warts cannot be used to decide whether caution is needed because HPV can be passed on to another person even when warts or other symptoms are not visible. HPV can be present for years with no symptoms, so it can be difficult or impossible to know whether a person with whom you might have sex might be infected with HPV.
The longer a person remains infected with any type of HPV that can cause cancer, the greater the risk that infection will lead to cancer. For these reasons, postponing the beginning of sexual activity and limiting the number of sexual partners are two ways to reduce the chances of developing penile cancer.
A new vaccine has been approved by the FDA that will protect against infection with HPV types 16 and 18. It is currently recommended for use in young females before they become sexually active, and it is being looked at for possible use in males. While studies have not yet been done, the hope is that this may eventually help prevent cancers linked to HPV, including penile cancers.
Smoking, another factor associated with increased penile cancer risk, is even more strongly associated with several other very common and often fatal cancers, as well as non-cancerous conditions such as heart disease and stroke. Quitting smoking or never starting in the first place is an excellent recommendation for preventing many diseases, including penile cancer.
Some men with penile cancer have no known risk factors, so it is not possible to completely prevent this disease.
