Truth: Leukemia, also known as blood cancer, is a class of malignant clonal disease of hematopoietic stem cells for which bone marrow transplantation is the ultimate solution. For adults, hematopoietic stem cells are mainly found in the bone marrow, so before the 1990s, bone marrow transplants required a needle puncture to extract a portion of the bone marrow from the donor's body. But with advances in technology, people are now screening A peripheral blood for hematopoietic stem cells for transplantation, making bone marrow transplants easy to perform and much less risky.
For the donor, a bone marrow transplant consists of a "mobilization shot" and a blood draw. The blood draw is not harmful to the human body, as we have all experienced. The main component of the "mobilization shot" is recombinant human granulocyte colony-stimulating factor. This substance originally exists in the human body and is important for maintaining normal hematopoietic function. The short-term adverse reactions after the "mobilization injection" include low fever, fatigue, muscle pain, etc. Generally, no special treatment is needed, and will be relieved and subside by themselves after stopping the medication.
