Chemotactic factors in the brain

While I was sitting in on a neuropathology signout, another idea came to me: Would it be possible to inject chemotactic factors into the brain to attract the tumor cells into one area for subsequent removal? When I said it out loud, it turned out that the attending is researching exactly that. I felt proud - and I hope the idea works out.

How about this: What if some cellular congregations are misdiagnosed as neoplasms, while being a result of a focal oversecretion of chemotactic factors?
