In our Clinical Department, various professional groups from Nursing, the office, the study office, the medical department, the psychosocial team, the laboratory and quality management work closely together to ensure optimal care for our patients. We are supported in this by the "Association for Children with Cancer" from Hanover. We also work closely with many other Clinical Departments in and outside the MHH, for example via the network of the Society for Pediatric Oncology and Hematology. We also regularly take part in national and international congresses to keep up to date with the latest treatment developments.
