Hi Heather
Like the others have said these are done for a baseline for later comparison. I had a CT chest and abdo, Bone scan and Bone densitometry scan before I started chemo. My oncologist said it's like opening a can of worms cos they report on every little cyst smudge and blob they see most are usually nothing but you have to be sure. Quite normal. I finished all my treatment last Friday (radiation) and see the oncologist on March 3rd when I'll be put on tamoxifen. Also hoping to get the ok to go back to work!
Good luck
Sarah
