Surgical resection is a critical procedure in modern medicine, with tens of thousands performed each year to address serious health conditions like cancer. The function of the resection is to surgically remove diseased, damaged, or infected tissue or an organ from the body, often as a life-saving measure. This procedure is a cornerstone of treatment for many complex medical issues, from tumors to chronic inflammatory diseases.

Approximately 72% of cancer surgeries rely on margin analysis to determine the success of tumor removal. Understanding **what is the meaning of margin in medical** terminology is crucial for patients, as it can directly impact treatment decisions and prognosis.

According to the National Cancer Institute, a negative margin suggests all visible cancer has been removed during surgery. This crucial concept, which defines what is the margin in excision, is the border of normal tissue removed around a lesion to confirm complete removal of the abnormal cells. Understanding this is a vital step for any patient undergoing an excisional biopsy or tumor removal.
