Step-by-step explanation:
A therapeutic agent that works against abnormally rapid cell growth is called an antineoplastic agent.
This statement is true.
Antineoplastic agents, also known as anticancer drugs or chemotherapy drugs, are medications used to slow down or stop the growth of cancer cells. These drugs interfere with cell division in various ways, such as by affecting the duplication of DNA or the separation of newly formed chromosomes. They are designed to target rapidly dividing cells, which is a characteristic of cancer cells.
