In November 2022, Lele, a second grader, was diagnosed with Hodgkin's lymphoma. After thorough research, his mother took him to Professor Yonghong ZHANG's team at Beijing GoBroad Boren Hospital. Upon admission, Lele quickly underwent a tumor assessment, received a pathology consultation, and had imaging tests including MRI and PET-CT, as well as a bone marrow biopsy. 

It was confirmed that the tumor was limited to the lymph nodes in his neck and above the collarbone. Professor Yonghong ZHANG's team staged Lele's condition based on the tumor's location, size, and the presence of B symptoms, and developed a customized treatment plan. Following six cycles of chemotherapy, which were carefully managed by ZHANG's team and supported by attentive medical staff and Lele's mother, Lele achieved complete remission. Now, Lele is still vibrant and sociable, back at school, and happily running on the sunny playground.
