In June 2008, my mom was diagnosed with bile duct cancer, and the whipple surgery was performed. Things were fine for a few years and in June 2011, they detected a tumor in her lung and since they could not determine if it was a metastasis with 100% certainty, they removed her lung. We received confirmation afterwards that it was in fact a metastasis. Then this past november, they detected a spot in her pancreas. They sent her for a pet scan and it was detected that she also had a spot in her jaw and shoulder (all less than 2cm). Right now, she is receiving chemotherapy once per week. In reading, I can see that this would likely be considered Stage 4 (which I know is bad), but I would really like to know what this means in terms of time (i know there is not sure thing, but even an approximate amount of time could help us deal with the situation better).
