The first, simple to use, step-by-step “check yourself” testicular cancer app has been launched by testicular cancer charity The Oddballs Foundation.

With 16,000 new cases diagnosed in the UK every year, early detection means 95 per cent of males will make a complete recovery and so the charity is encouraging men and boys to download the app and check themselves regularly.

Each month a celebrity will encourage users to check themselves, via a video on the app – the first being from former footballer Alan Shearer – and then users can use the app's easy-to-follow diagrams and video instructions. The app will send an alert once a month to encourage users to check themselves with the 'how to guide.

Patron of The Oddballs Foundation and former Premier League footballer Stephen Harper said: “This is the most common cancer for males aged 18 to 35 and unless we get a reminder, most of us just don’t think about it... This could save your life, your son’s life, your father or grandson’s life. It’s that important”.  

The app is available from the Apple or Andriod app stores – just search for ‘Oddballs - Check Yourself’.
