Hi all. So, my brother is supposed to have his second round of chemo begin today - still waiting to hear from the hospital to tell him to come and check in. This is frustrating!! It's been nearly three weeks since he began his chemo, and I feel like we're waiting too long in between treatments. At his first round the tumor shrank to about 1/2 the size that it was within the first 24 hours, and continued to shrink. But now its back and about the same size it was before he started chemo. What does this mean? Anyone have a clue?
