Tumor

From Wikipedia, the free encyclopedia

Jump to: navigation, search

A Tumor or tumour (via Old French tumour from Latin tumor "swelling")[1] originally meant an abnormal swelling of the flesh. In contemporary English, tumor has evolved to become synonymous with neoplasia [2], all other forms being called swelling [3]. This tendency has also become common in medical literature. The noun tumefaction, derived from the adjective tumefied, is the current medical term for non-neoplastic tumors [4].
