Hello all.My Dad had an endoscopy on 30/1/2019.He has been losing weight for the past 6 months and has had slight difficulty with swallowing.The endoscopy found several white fatty like small lumps on his esophagus.The endoscopologist told us that he will need a pet scan asap,along with a diagnosis of the biopsy.We are so worried and frightened as to what the results will be,Dad is eighty one and we cant imagine being without him. Kind wishes to all on the forum,Nigel.
