We don't understand a lot about the Large Granular Lymphocytic Leukemia, except what the Dr tells us, which is very little.I am not so sure that he has answers sometimes, but he is treating my husband and my husband is doing well.We don't understand exactly what this rare thing is or how it is making him ill or if he will live a long life(He is 75and was diagnosed under a year ago but been ill for about 2 years with it).Can anyone help us with answers?
