'antiangiogenesis' originates from Greek elements: the prefix 'anti-' meaning 'against' and 'angiogenesis' from Greek 'angeion' (vessel) + 'genesis' (origin/creation).

'angiogenesis' is a modern medical/Neo-Latin formation from Greek 'angeion' (vessel) + 'genesis' (creation). The compound 'anti-' (from Greek 'anti') was attached in 20th century medical literature to denote inhibition; the specific compound 'anti-angiogenesis' and related term 'antiangiogenic' were popularized in oncology research (notably since Judah Folkman's work on tumor angiogenesis in the 1970s).

Originally, 'angiogenesis' meant the formation or growth of blood vessels; with the addition of 'anti-' the combined term came to mean the inhibition or prevention of that process, especially in therapeutic contexts.
