Arsenal football manager Arsene Wenger has joined rivals Sir Alex Ferguson and Sir Bobby Robson to support Cancer Research UK's Man Alive initiative.
Wenger has backed the summer-long campaign, which is launched at the end of May. Man Alive uses public figures to urge men to contact doctors themselves when cancer warning signs occur, rather than relying on their female partners, who are more likely to do so.
He said: "Men should be encouraged to be more health-conscious, look after themselves and talk about issues which could seriously affect their wellbeing."
Former England manager Bobby Robson has survived two bouts of cancer and says he owes his life to his wife, who nagged him to see his GP. He supported the campaign alongside Ferguson last year.
A charity spokeswoman said: "These men are a perfect fit for the campaign. Their presence will inspire many men to take responsibility for their own health."
