Saw Mr M today, who said he was pleased with progress. Why I lost a lot of blood four days after the operation and where it came from remain a mystery, but does it matter (my comment, not his)? The chunk that was removed measured 85 x 50 x 30 mm, and the tumour itself was an irregular ellipsoid, the major axis of which was 33 mm. Generally these lymphomas are more symmetrical. Mr M showed us the photographs taken during the operation, and has kindly promised to email them to me or send a CD. He said that the bacteria helicobacter pylori had been shown to cause MALT in the digestive system in a majority of cases, and it was unusual to find it in the lung.
