Jen, welcome. Sorry you need us. Please keep a positive attitude. I, too, was a stage IV cancer victim and have beaten it. I also found my tumor by finding a lump in my neck. Make sure you are in a major comprehensive cancer center to insure the most up-to-date treatment possible. And yes, they will make appointments for you before you understand the reasoning for them because they know what treatments you need and who to see. It sounds like you might have a fairly large tumor like lots of others have had on this board and defeated this disease none the less. So keep at it, you can beat this thing as well. A positive attitude is a big part of a successful treatment regimen, so keep it positive and don't let this get the upper hand. We've all been there ourselves or been there with our loved ones and you can win this too. Many prayers coming your way. The Lord will walk this walk with you.
