Ken: I would assume that the treatment plan is going to work.... shrinkage and then surgery.
Also, my 3rd cancer was not noticed until Feb 2005. I had an August, 2004 scan and the cancer was there then, but the radiologist missed it. My pulmonolgist showed me where it was when I visited him in February. He said it is very easy to see a missed cancer 3 months later when you know where to look for it on the film. My cancer was about 7 mm when it was missed.
