Describing something that stops or slows down the growth of cancer cells or tumors.
Doctors often use antineoplastic drugs to treat various types of cancer.
Antineoplastic is formed from "anti-" (meaning against) and "neoplasia" (from Greek "neoplasia", meaning new growth). The word refers to agents that work against new growth, particularly in the context of cancer treatment.
Think of 'anti-' meaning against and 'neoplasia' meaning new growth — antineoplastic refers to something that works against new growth, especially in tumors.
