Neoplasm

Also known as: tumor, tumour, new growth

Any abnormal new growth of tissue, which may be benign or malignant.

Definition

A neoplasm (literally "new growth") is any abnormal mass of tissue that grows beyond what the surrounding normal tissue does, even after the original trigger is removed. Neoplasms can be benign (non-cancerous, slow-growing, do not invade), or malignant — cancer — with the ability to invade surrounding tissue and metastasise.

A biopsy is usually required to determine which kind of neoplasm is present. "Tumour" is often used as a synonym, although strictly speaking a tumour is just any swelling.
