Hi Jen, sad to learn that you are just diagnosed with stage 4 cancer but glad that you have found us in time. What is your primary site of cancer? What keep you from losing weight at this moment when treatment has not yet started? I have lost several lbs too before diagnosis but have stopped losing when I ate a lot prior to treatment because I knew that once I started treatment, I would lose a great deal more.If you need a PEG right now, does it mean you cannot eat by mouth?
Hope you won't mind my being so inquisitive. Just want to offer the right help and don't panic now, a lot of stage 4 cancer patients survive and turn a new leaf after treatment. I am one of them.

Karen.
