"I was diagnosed with prostate cancer in 2005. I'd had symptoms for five years but like most men, had a fear of being examined so didn't go for a check-up. Mistake. I've had a rough time through treatment and being gay has made it tougher, I haven't had the courage to even talk to my GP or specialist about issues. Signing up as a Cancer Voice has given me a sense of purpose and control of events that I didn't have during my treatment. I've reviewed books on prostate cancer as they're often written with older men in mind, I've become a member of a research reference group, and I've volunteered to speak to the gay media about my story. If being involved with Cancer Voices now makes life just a little less frightening for others going through a cancer diagnosis, then my whole experience will have gained meaning." Simon, 41, Dorset
"After being diagnosed with mouth cancer in 2005, I became self-conscious about being both young and ethnic - my family is originally from Jamaica. Now, I've signed up as a Cancer Voice so that my experience can help others and I can build up my confidence. I've given my views about involvement in cancer research for black and ethnic minorities. I'll also be going to local schools to talk to children and help them have a better understanding of cancer. It's good to feel useful again." Melanie, 24, Greater London
