@krissycanada, I want to reach out across the miles and offer a gentle hug, to let you know that I understand what you must be feeling right now. In my own experience, I was waiting for a liver transplant when I was faced with a possible cancer of bile ducts (cholangiocarcinoma) diagnosis and was ineligible for a liver transplant until I could be tested as cancer free. I felt that my life and my family's life was on hold while I waited and wondered and feared for my/our future. It is not easy to wait and wonder. And Colleen said it best when she said that if there is cancer present, it is best to find it early as possible.

Krissy, My advice, is to take each day as it comes. Try not to focus on the "What if's". It is okay to cry. It is okay to be afraid when undergoing tests and scans; it is okay to ask questions about and during tests and scans. Take someone with you. Always ask when to expect to get results and a follow-up appointment. Get phone numbers. Take notes. If found hope and support through my church family.
Krissy, I'm thinking of you. Let me know how I can help you.
