Cancer of the penis, or penile cancer, is a rare disease that mainly affects men over the age of 50, according to the NHS.
The exact cause of the condition is unknown, but you could be at risk of penile cancer if you’re a smoker, and carry the human papilloma virus (HPV).
More than 90 per cent of penis cancer cases are squamous cell penile cancer, which affects the cells that cover the surface of the penis.
These are the signs that you should see a GP now.
“You should be aware of any abnormalities or signs of penile cancer,” said the NHS.
“If you experience these symptoms, it’s important to see your GP as soon as possible.
“It’s unlikely they’ll be caused by penile cancer, but they need to be investigated.
“Any delay in diagnosing penile cancer could reduce the chances of successful treatment.”
Symptoms of penile cancer include bleeding from the penis, or from underneath the foreskin.
If you find a growth or sore on the penis, and it doesn’t heal within four weeks, you should also see a GP.
Other signs include a foul-smelling discharge, developing a rash on the penis, and if the skin of the penis or foreskin changes colour.
Phimosis may also be a symptom of penile cancer. The condition describes a thickening of the skin of the penis or foreskin, that makes it difficult to draw back the foreskin.
It’s not always possible to prevent penile cancer, but you could lower your risk of the disease by maintaining good hygiene.
Maintaining good penis hygiene can prevent the bacterial and viral infections that increase the risk of the cancer.
It’s important to use condoms to lower your risk of catching HPV, the NHS said.
Also, regularly washing your penis with warm water, including under the foreskin, could also lower your risk of the cancer.
