Definitions related to benign neoplasm:
-
(neoplasm, benign) A general term used to describe autonomous growth of tissue where the originating cell type has not been characterized. The term benign indicates the absence of morphologic features associated with malignancy (for instance severe atypia, nuclear pleomorphism, tumor cell necrosis, and abnormal mitoses).CDISC TerminologyClinical Data Interchange Standards Consortium (CDISC), 2021
-
(benign tumor) A growth that is not cancer. It does not invade nearby tissue or spread to other parts of the body.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021

(benign tumors) Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain. Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor. Treatment often involves surgery. Benign tumors usually don't grow back. NIH: National Cancer InstituteMedlinePlusU.S. National Library of Medicine, 2021
-
A neoplasm which is characterized by the absence of morphologic features associated with malignancy (severe cytologic atypia, tumor cell necrosis, and high mitotic rate). Benign neoplasms remain confined to the original site of growth and do not metastasize to other anatomic sites.NCI ThesaurusU.S. National Cancer Institute, 2021
