Tumour
From Wikipedia, the free encyclopedia
Tumour means swelling, but the word is sometimes used to mean tissue growth where it should not be growing. Tumours are either malignant (harmful) or benign (safe).
The Tasmanian Devils in Tasmania, Australia are in danger of becoming extinct because of a malignant tumour that grows on their face.[1]
