I was diagnosed with CLL in 1997 though probably had it for some years before that. I had chemo in 2004 and again in 2008. Then I had a right pneumonectomy in 2010 for cancer. Now my haematologist is talking about more chemo since my platelet count is around 34,000 and the infiltration of the bone marrow is at around 95%. I would like to know what happens when the infiltration of the bone marrow reaches 100%? At present the chemo has been postponed because the haematologist doesn't want to risk further cancer in the remaining lung, whereas the pneumologist says that the chemo would be alright if it is necessary. I don't know what to think! Help!
