once you have bone mets

[penelope]

how fast do they grow? Is it a slow process over years or fast?

I am concerned as I have had a pain in my butt that comes and goes since this whole cancer thing started 2.5 years ago.

The pain that I feel is in my butt cheek and sometimes travels to the front of my leg. It hangs around for about a month and the will disappear. It does not wake me up, but I feel it when I am awake. I had a bone scan during a particular troublesome period with it in Mar 06 which was clean. I then had a CT scan in Oct 06 for other reasons and it noted "mild sclerosis and possible early subcortical cyst in the right scroiliac joint." Could this have actually been bone mets missed? It has been over a year and my blood is fine, other than being a little anemic due to iron. Wouldn't it have shown up in my blood by now?

Feeling a little like I am falling off the ledge lately ladies.
Last night is the first night ever that I dreamed of being stage IV.

Opinions from the experts please!
