All the best to him.
From Man Uniteds web site:
Statement issued on behalf of Bryan Robson, OBE.
Bryan Robson underwent an operation to remove a tumour from his throat on 3 March, 2011 in a hospital in Bangkok.
The laboratory report revealed a cancerous tumour, which will need further treatment. The oncologist is confident that the condition is treatable.
At this moment, Bryan is fine to continue with his role as Thailand coach and his role as Ambassador of Manchester United.
Bryan and family have requested that he can continue with his treatment in private and ask that their privacy is respected.
