Cancer does not discriminate by gender, race, age or socioeconomic status. To shed light on the increasing number of cancer cases worldwide, World Cancer Day is observed every year on February 4 to raise awareness about detection, treatment and prevention.

Each has spoken openly about their prostate cancer diagnosis and treatment, highlighting the importance of early detection and the need for targeted screening programs.

What they’re saying

“Cancer touches us all. Like so many of you, Jill and I have learned that we are strongest in the broken places. Thank you for lifting us up with love and support.”

— Joe Biden, Former President of the United States (Social media)

“I want to, as it were, come out. I want to add my name to the long list of people calling for a targeted screening programme. I don't particularly like discussing my personal intimate health issues, but I feel I ought to. Let's be honest. Men are not very good at talking about their health. We tend to put things off.”

Their willingness to share their stories can help reduce stigma, encourage more men to prioritize their health, and drive progress in prostate cancer screening and treatment.
