I read that some treatments use cytostatic drugs to fight cancer.

Yeah, those drugs are designed to slow down the growth of cancer cells.

Root Explanation
Cytostatic is formed from "cyto-" (from Greek "kytos", meaning cell) and "static" (from Greek "statikos", meaning causing to stand or stopping). The word describes something that stops or inhibits the growth of cells.
Memory Tip
Think of 'cells' ('cyto-') being 'stopped' ('static') — that's what cytostatic means.
