Can i acquire cancer through lymphocyte immunization therapy?

Happy mother's day to all mom out there. I envy people who get pregnant and successfully deliver healthy babies spontaneously.

My pregnancy is really a challenge! I just had my third Smoflipid infusion the other day because I had an inflammed placenta. I heard a devastating news yesterday- one of my blood donor got sick. She suffered from unexplained bruises around her knees. Ouch...what could be the cause- leukemia or itp?

Oh my god! Let me google whether leukemia can be acquired through blood transfusion. According to the web, cancer cant be acquired through blood transfusion. It sounds funny, because cancer patients are not capable of donating blood. Another reason is the recipient immune system will be able to fight off the cancer cells. Oops... But I am taking Imuran- a strong immune suppressant used by kidney transplant paitients to prevent donor kidney rejection.

Another question... Is leukemia caused by retrovirus? Yep, it maybe caused by human t-lymphotropic virus.  http://en.m.wikipedia.org/wiki/Human_T-lymphotropic_virus

I hate blood products. Ivig provides alternative to LIT. But, it also poses the risk of viral infection and prions. I am pathetic. Is this what a product of my stupidity or my leap of faith? My friends were safe with LIT and Ivig. Huhu... Not me. I pray my donor doesnt have leukemia. What can her diagnosis be? Either ways, it is scary. If she has idiopathic thrombocytopenia purpura... Anti-platelet antibody what will be my platelet count next week.? I guess I may cry when I consult my fairy godfather (immunologist).
