Resection

Also known as: surgical removal, excision

Surgery to cut out a tumour, often together with a rim of surrounding normal tissue.

Definition

Resection is the surgical removal of a tumour, typically together with a rim of surrounding normal tissue to give a clear margin. Nearby lymph nodes may also be removed in the same operation for staging.

Examples include lumpectomy and mastectomy for breast cancer, lobectomy for lung cancer, colectomy for colon cancer and prostatectomy for prostate cancer. Whether a tumour is "resectable" depends on its size, location, relationship to vital structures, and the patient's overall fitness for surgery. Neoadjuvant therapy is sometimes used to shrink a borderline-resectable tumour first.
