Results Of 2nd Biopsy Back

We got the results back today and the biopsy confirmed that the tumor has been completely dissolved from round one and round two of chemotherapy.  So thats good, thats what we were hoping for.  Now as soon as Ashlynn's back heals up ( 1 week ) they can check back into the hospital to begin round three.  So you ask if the cancer is completely gone why continue with chemo?  Well they do that to make sure it does not have any chance to come back.
