It isn't always possible to prevent penile cancer, but you can reduce your chances of getting it.
One of the main ways you can reduce your chances of developing penile cancer is to give up smoking if you smoke.
It's also important to maintain good penis hygiene to prevent the bacterial and viral infections that can increase the risk of penile cancer.
This is easier if you were circumcised as a child, but there are steps you can take if you haven't been circumcised.
Simple penis hygiene can include:
using condoms to reduce the risk of catching HPV
regularly washing your penis with warm water, including under the foreskin
There's little evidence to suggest that being circumcised as an adult will reduce your chances of developing penile cancer.
