Prostate cancer is the most common cancer in men - with 112 people being diagnosed every single day.
Survival rates have improved dramatically in the past 20 years - but it's still the biggest killer after lung cancer - mainly because people catch it too late.
Now a campaign is being launched to persuade people to talk - to overcome the embarrassment and be more open about the disease
It's called "Men United v Prostate Cancer" to appeal to male instincts and it's hoped a new and open approach will improve the chances of survival.
David Wood has been speaking to Kenneth Jeffers, a cancer patient from Herne Bay, the comedian Bill Bailey and Owen Sharp from Prostate Cancer UK.
