The Championship club say Ikeme, 31, returned "abnormal blood tests" during pre-season testing and further checks confirmed the diagnosis.
The 31-year-old has been with Wolverhampton Wanderers for his entire career, making more than 200 appearances for Wanderers.
Rather sad news came out of Wolverhampton Wanderers on Thursday, with the club's Nigerian goalkeeper diagnosed with acute leukemia.
"That relates to both players and staff as Carl has been at the club for a very long time and remains such an integral personality within the group".
Wolves' Managing Director Laurie Dalrymple adds: "At the same time, we all know what a fighter and a competitor Carl is, and I have no doubt that he will take all of those attributes into this battle. It is this strength that we want Carl to show, and that is what we believe will see him through". Stay strong @Carl_Ikeme and have faith. You will beat this like a champion.
De Laurentiis: "Reina è un finto problema. Mercato? Magari arriva Mister X…"
Pepe è coperto dal contratto. "E poi non è da scartare l'ipotesi di un mister X, qualcuno che a voi giornalisti è sfuggito". E' la domanda che tutti i tifosi del Napoli si stanno ponendo nelle settimane precedenti il campionato.
"Our thoughts are with Carl at this hard period".
"We have been told that he will start chemotherapy immediately".
"We are speaking to Carl regularly, and sending him our very best wishes as he comes to terms with this news and starts his recovery".
The Barca safehand on twitter said " A tweet simply too short to express my thoughts about Carl Ikeme", afterwards he turned to his facebook which gave him more space to express himself and encourage other goalkeepers even as he expressed hope that the Nigerian global can adopt a positive mind in his period of trial.
Ikeme's Nigerian team-mate Brown Ideye also tweeted his support.
