Prostate cancer is the most common male cancer in the UK, accounting for almost a quarter of male cancers.
Each year, nearly 35,000 men are diagnosed and more than 10,000 die from the disease.
Sarah Jarvis is the inhouse doctor for BBC Radio 2's Jeremy Vine Show, and has tips on the symptoms all men should look out for.
The Jeremy Vine Show is broadcast Monday to Friday at 12:00 BST on BBC Radio 2. Or listen again via the link.
