Julian Trudy is correct .Currently there are stem cell transplants where they wipe out your bone marrow and replace it from a genetically compatible doner marrow cells
Second .There is CarT .Therapy approved after first failure after traditional chemo.This entails taking blood from a patient ,sending it out to be genetically engineered to attack the either the CD19, or CD20 protein on the surface of your Cancerous B lymphocyte ..Respone rates very high .New therapies less toxic coming out every few months
Stay positive , this in the not too distant future will be a bad memory .Dont underestimate the support and unconditional caring the people are on his site

No has nothing to do with blood type .It is the genetic mutations in your lymphocytes that cause the disease

Thanks so much

Hi Julian, Frank8 is correct. That said some people have their blood drawn and 'spun off then replaced! Having had apheresis for my Stem Cell transplant I can tell you it is only unpleasant it also carries some unnecessary risks.
Are you anemic or is there any other blood related deficiencies? cheers Trudy x
