Pancreatic Cancer

My husband has been diagnosed with stage three pancreatic cancer, he was diagnosed on 07/2018 &  he has had three to four MRI and or cat scan in  the past months and nobody saw this. he called me at the office which is really rare so I called him back immediately and drove him to chilton memorial hospital where we stayed for 5 hours n found mark had a 5.6 centimeter tumor we where shocked. like i said we had so many MRI'S and cat scans since october we only found  out now almost a year later. when he had surgery for the tumor they had to remove the pancreas and spleen undo a  twisted bowl fix a hernia and remove a 9 centimeter tumor yes 9 not 5.6. he has been really tired and in sever pain. we went to memorial sloan kettering they want to do more test cause the cancer mark has is very rare. in the past 10 years or more there are only 30 cases. so mark might to have more exploratory surgery then an aggressive amount of chemo and radiation. we go tomorrow back to MSK for cat scan to make sure it did not go to the lungs. so right now it is so hard. We have a 10 year old Willem and a 5 year old Harrison. they are the light of our lives and what keep us strong and positive. They do require a lot of everything and school starting no clothes for them yet..... We are falling behind on bills and I am so scared we will get so bad that we won't come out. Please anything will help....
