treatment ?

I still haven't heard from MDACC about moving up my treatment to this week instead of next. I'm calling in the morning, and will keep calling till I get an answer. My lump is so large now that I can see it when my arms are at my sides. Last week, I had to raise my arm to see it, and 2 weeks ago, I had to press my hand around it to push the skin down. I'm getting scared, and angry. Maybe I made a mistake not starting Chemo with KS.
The Dr obviously thinks a week won't make a difference, but this has gone from golf ball size to duck egg in 6 weeks.
