As soe of you will know, my father was rushed into hospital today. His "collapsed lung" has turned out to be a severe case of pleural effusion of the right lung. Preliminary analysis suggests that this is as a result of a chest infection, but although there is no evidence of anything more sinister at this stage, doctors are not ruling out the possibility of a tumour.
Mark and I have been at the hospital all day, and will - no doubt - be there tomorrow. I will post updates as often as I can.
Remember us in your prayers
