Have you ever seen footage of a white blood cell taking apart a cancer cell? This is worlds closer to unlocking that power than hoping a stray radioactive particle bumps the right lever. Perhaps the need for two separate medicines/agents to make this special cocktail and trigger the perfect immune response has been the elusive part?

Could you link to some footage of a white blood cell taking apart a cancer cell?

Yeah, this is an NK cell triggering an apoptotic (self-destruct) response in a cancer cell. So it's basically sending a kill-signal to the cancer cell, which then kills itself. This doesn't work for all cancers, though. In fact, one hallmark of cancer is unresponsiveness to apoptotic triggers.

Ok, here's one with T-cells from Cambridge University: https://www.youtube.com/watch?v=ntk8XsxVDi0

Iodine is critical to at least one of the pathways to apoptosis, and has been found to cause (allow?) it in several types of cancer.

As someone commented on that Youtube video: "I love watching cancer die. Great video!". Me too!
