I can fully sympathise with you Andria -- my 23 year old had to have an operation last October to remove a group of tumours intertwined with the nerves running down his neck.
It was quite a serious operation but the surgeon was brilliant -- and it seems the best in Europe .
He made an amazing fast recovery .
He went back for a check up a while ago and they found one that they had missed in the previous op .
Obviously his mum is worried and quite rightly is refusing to go to Cyprus until it's all sorted out and he's ok.
Give our love to your little one -- and don't worry to much as children can sense this and make themselves worry too.
Best wishes Bill
