Yes, I find that one of the reasons why the general public gets so suspicious about "how come we haven't found a cure for cancer yet despite so much research" is because of a failure to grasp the concept of cancer being a general term for a myriad of diseases.

Great advances have been made, but in many cases a lot of further research is needed both to improve efficacy and to minimize damaging side effects (lest we end up unleashing the zombie apocalypse, hehe).

Thanks for this thoughtful comment, @theodorelib!
