Well I'm pleased to say that granda's op went very well. They believe that they have got all the cancer, thankfully. There was some seepage into the fatty tissue but they don't appear to be too concerned. They aren't giving him chemo or radiotherapy but keeping a regular eye on him as it is very likely that it will come back. He hasn't been 100% since the op with chest infections etc but otherwise is in very good spirits! Thanks for all the reassurance and advice at the time - really made a difference!!
