Help!! Need to shrink lymph node fast

[PatE]

Hello
I am Her2 positive BC since 2007, I have now been diagnosed with another primary colon cancer. Been on he herceptin since 2008 and more recently tykerb and Herceptin.
I have been having extreme pain especially after I eat so a CT was done to determine the cause. At first they said gall bladder but after they compared the CT and PET together they now say its my lymph node pressing on my pancreas.
I'm at a loss as to how to proceed, I've lost 17 pounds and cannot eat. One doc has already mentioned a feeding tube but I'm not ready to go there. I hope some of you smart women can help point me a the right direction. I'm checking to see if cyber knife is an option or possibly surgery. I haven't seen anymore info on TDM1, was hoping for announcement at San Antonio this week.
The colon mass surgery is on hold until they get this figured out, I'm really scared now I feel like I'm losing control!
Any thoughts or info would be greatly appreciated
Thanks
Pat
