It means the surgeon removed tumor tissue, but visible (macroscopic) cancer remains after the operation. R2 resection is commonly discussed in surgical oncology, pathology reports, and tumor board planning. It helps the care team describe how complete the surgery was and what additional treatment may be needed."}
