Hi Johanna in Iceland With Frozen Gloves
I don't have any experience with Taxotere or liver mets, but know that some of the others do and will share their experiences with you. But I do know about anxiety! It's a normal part of this experience, and it's hard not to worry about every "ping". Sometimes response isn't as quick as we'd like to see, but that doesn't mean you're not going to have good results, it may just take a little more time.
About the tumor markers; have you been following the information provided here on the Bayer Serum Test? There's a thread above with very good contact info for your onc on how to go about ordering this test, if you and your oncologist think it's appropriate for you at this time.
Hope the frozen glove strategy works!
