Daerim St. Mary's Hospital said its radiation oncology center exceeded 20,000 radiotherapy cases on August 21, 2026. The milestone came about two years and one month after the center opened and delivered its first treatment in July 2024.
Breast cancer accounted for most of the hospital's 20,000 treatments. The hospital also treated primary rectal, liver, and lung cancers, as well as cancers that had spread to the brain, lungs, or bones.
What the milestone represents
Daerim St. Mary's Hospital reached the milestone after adding radiotherapy to its breast cancer care pathway through the radiation oncology center. The hospital described the volume as evidence of stronger capacity to connect breast cancer treatment services.
The center operates an Infinity HD linear accelerator and has delivered intensity-modulated radiotherapy, volumetric modulated arc therapy, and image-guided radiotherapy. The milestone counts treatment cases rather than individual patients or clinical outcomes.
Clinical context and limits
Radiotherapy is used alongside surgery and chemotherapy as a major cancer treatment. A qualified physician may consider it before or after surgery, as an additional treatment, or on its own according to the cancer type, stage, and the patient's condition.
Health Chosun, a Korean medical trade outlet, and Rapportian did not report patient-level effectiveness, side effects, or recovery findings for these 20,000 cases. Treatment decisions therefore require attention to individual variation and a consult with a qualified physician about expected benefits, possible side effects, and recovery considerations.
Questions for a treatment consultation
Patients can ask why radiotherapy is being considered for their cancer type and stage, and whether it would be used before surgery, after surgery, or as a standalone treatment. The treating physician should relate the proposed role to the patient's condition.
A useful consult should also cover the planned radiotherapy method, possible side effects, and factors that may affect daily life and recovery. These answers need to be individualized rather than inferred from the hospital's cumulative treatment count.
