What causes prostate cancer
There is no clear cause of prostate cancer, but a number of things have been linked to an increased risk of the disease developing.
Age is one of the biggest risk factors, according to Cancer Research UK.
The charity explains: “Prostate cancer is more common in older men and is more common in men aged 75 to 97 years.
“One in six men in the UK will get prostate cancer at some point in their lives.”
Other risk factors include ethnicity, being overweight or having a history of prostate cancer within the family.
