Tumor or tumour (via Old French tumour from Latin tumor "swelling") is an abnormal growth or mass of tissue. A tumor can be either malignant or benign. Nearly all tumors are examples of neoplasia, although certain developmental malformations or inflammatory masses may occasionally be referred to as tumors.
