I think what he said must have been Lymphedema.  The more I read about it, I think it is what Aunt Helen had in the summer when they found her cancer.  Unfortunately if it is that, from what I can read there is no cure... just treatment.  Oh well one more thing to look forward to to see it this is it.  I think I would rather have the GI symptoms from Lymphedema than the swelling of the leg that Aunt Helen had.... I do NOT want to be in a wheel chair.
