I would like some insight/advice to a current situation with a family member. My brother, who is 54 years old, recently had the CA 19-9 blood test done and results came a little elevated. From what he tells me, the normal values are below 37 and he showed 45 the first time. He then had the same test repeated after 2 weeks and it was 51. The doctors tell him to repeat in a month's time. However, after doing some reading on this subject, it seems pancreatic cancer is a deadly form of cancer and i do not feel comfortable with him waiting 1 month for a repeat test. He doesn't seem to have any symtpoms.
a.) So, first of all, are these results alarming?
b.) Would it be advisable to wait 1 month for a repeat test or should he get a CT scan, MRI or some other procedure done to get to the bottom of this immediately?
c.) What are some of the best gastroenterology hospitals in US he can go go to?
thanks for the advice and insight.
