"What is the success rate of the bone marrow transplant?" After Jerome glanced at Selina's uneasy face, he knew what she was worried about. Feeling a little agitated, Jerome forced himself to calm down and questioned Offner. Offner specialized in leukemia and bone cancer. He was an authority in the medical community. Jerome had a hard time getting him. "If suitable bone marrow is available, I can guarantee a 90% success rate of the operation. However, the problem is that this patient's blood type is special, so bone marrow matching is extremely difficult. I can't tell whether he can survive until the day he finds the bone marrow donor." Offner said. He smiled confidently as if the bone marrow transplant was a piece of cake for him. Jerome nodded and seemed to be lost in his thoughts.
