My doctors constantly ask me how I feel to qualitatively gauge the progress of my treatment. What I've noticed is that I have a little more pain after my chemo treatments but afterwards I feel a bit better. It's difficult to say whether feeling better now is an improvement from feeling better before and I have a difficult time differentiating my aches verse pains (I really have no idea what that means).
My doctor's NP told me that a tumor can become inflamed and then shrink down again after a dose of chemotherapy. She continued, "I like to believe that it's the chemo working specifically with that tumor." I thought that was nice because my back has been hurting me lately so I guess it's working :)
Next week I have my re-staging scans on Sunday and Monday to quantitatively evaluate my treatments. The NP explained that they should be able to see the tumor dying from the inside out. We're hoping to see that the cancer has stopped spreading which will be great news or better yet that the tumors are shrinking.
If everything looks good then we'll keep steering the course and if doesn't then we'll cook up a new cocktail for next round. We still have a large arsenal of available treatments and are optimistic on killing this disease.
