Spanish journalist Guillem Balague has confirmed that Barcelona are due to make an official statement today via his Twitter account;
Tito hasnt been operated yet. Players will be told all this aft. Club of course looking for replacement. Now time to be prudent #animsTito
What the news means for Barcelona moving forward is a little unclear. It seems quite apparent that for the good of his health Vilanova will have to step down from his role with the club which opens up a variety of possible replacements in terms of manager.
We took to Twitter to gauge the initial reaction about the news from those involved in the game and from general fans.
@GaryLineker - Very sorry to hear Tito Vilanova, the Barca coach, is undergoing surgery after a cancer relapse. Thoughts are with him.
@BumperGraham (Graham Hunter) - If the news is confirmed, as fear it will, that Tito Vilanova's had a relapse in his fight v tumour surgery 1yr ago it'll be brutally unfair

@sterling_m - Awful news about Tito Vilanova's cancer relapse. Wonder if Luis Enrique steps into his place coaching Barcelona now; can't see Pep return.
Barcelona are yet to officially comment on the situation with their players seemingly mute until they know the entire situation.
