Four out of five men at higher than average risk of prostate cancer are unaware of the danger and are therefore not having the vital conversations with GPs that could save their lives, according to new research from the health charity, Prostate Cancer UK.
It means thousands of men may miss out on being diagnosed at an early stage, when treatment for the disease is most effective.
Prostate cancer kills one man every hour; the majority of early cases are symptomless, and a lack of accurate tests for life-threatening forms of the disease means there is no national screening programme.
