disease. he was my best friend. he was and he will always be my best friend. literally we used to say we were each other�*s twin, we had the same mindset and we were very, very close so it's very difficult without him. danielle wasjust 25 when her dad johnny died after being diagnosed with prostate cancer. he was only 63. they were really close so losing her dad to a disease that, if caught early enough, is very treatable has been hard to take. his diagnosis came as a shock so it was in 2015. he did have some symptoms, now i realise, probably must have started a couple of years beforehand. but for that diagnosis you just don't think it's ever going to happen to you, you don't think it's going to affect your family. johnny died two years after being diagnosed. the charity prostate cancer uk and the nhs are both worried there could be thousands of men who are living with the cancer but don't yet know it.
