Stem cell therapy for leukemia and other blood tumors is reliable, the effect of other tumors is not very clear. Stem cell therapy is a new type of treatment, which uses the ability of stem cells to split into new cells to repair the damaged tissues and systems of the human body, so as to remove the cancer cells from the body and play a therapeutic effect. At present, stem cell therapy is mainly used in the treatment of blood tumors such as leukemia, and the overall effect is outstanding, but the effect is not very clear in the treatment of other tumors. Stem cell therapy is more mature in the treatment of leukemia, by taking stem cells from bone marrow and transplanting them into the patient’s body, helping him to re-establish a perfect hematopoietic function, so as to achieve the effect of cure.
