Dad getting diagnosed.

Hi. My dad is in the process of getting diagnosed with pancreatic cancer. Went in to the ER 1 week ago for under rib pain and a CT of his abdomen showed a large tumor on the tail of the pancreas that had attached itself to the spleen. Also, something seen on the kidney and with two small spots seen in his liver. Devastated to say the least. He saw an oncologist the next day while in the hospital who just said to wait and see after biopsy results and where to start. My mom and him are being so hopeful and positive while my sister and I are an absolute mess. My dad has looked up very minimal. He said he's going to do whatever it takes whether he needs to be lit up or sliced and chopped. I don't have the heart to tell him it's going to be stage 4 and probably inoperable. My mom said we don't know that but all I've seen online is so grim. He goes for a CT biopsy of his liver tomorrow instead of the pancreas which I don't understand how they can get all the information they need from that. His first oncology appointment is the following week. I feel like everything is taking so long. Meanwhile he is just at home looking and acting like how I've always known him. I just can't stop myself from reading and looking stuff up online. My mom is waiting for the oncology appointment to get the referral to John Hopkins which is nearby to us. This board is one of the few places online that gives me a small amount of hope.
