Chemotherapy is a broad term that is used to describe the practice of using drugs to treat cancer (as opposed to radiation and surgery). There are a ton of different ways that chemo works, including messing with DNA directly so cells can’t replicate, stopping tumors from creating new blood supplies, stopping tumors from being able to hide themselves from the immune system, blocking hormone signaling that would cause further tumor cell growth, stopping parts of the signaling pathway that would eventually cause more cell replication, and some other ways.
There is a ton of research being done in cancer drug development and new ones come out all the time.
