Did blood transfusions before bone marrow transplantation cause a high risk of rejection?

Patient's question:

I've been feeling discomfort in my lower back recently, especially when lying down, when I feel particularly painful in my lower back, and it takes a while to feel better. Sitting for a long time also causes pain. I went to the hospital for a thorough check-up, and the results were not good. The doctor recommended that I undergo a bone marrow transplant surgery, but I just went to donate blood for free a couple of days ago. Would there be a rejection reaction if I undergo a bone marrow transplant now? Is it likely to have a high rejection rate if I've received blood transfusions before the bone marrow transplant?

Doctor's answer:

1. When it comes to storing umbilical cord blood for babies, parents should maintain a balanced mindset. Avoid blindly following trends or overlooking its medical value. Instead, they should comprehensively evaluate and consider based on their family's circumstances.
2. If there is a history of genetic diseases in the family or if previous children have had leukemia or other immune-related disorders, parents should consider storing umbilical cord blood for the child about to be born.
3. If none of the above conditions apply and the family's financial situation allows, purchasing a storage plan is also a viable option.
4. Here, we urge parents who do not need to store umbilical cord blood not to discard their baby's umbilical cord blood lightly.
