Can pancreatic cancer be detected by blood test?

Can pancreatic cancer be detected by blood test?

Blood tests.

Certain substances, such as carcinoembryonic antigen (CEA) and CA 19-9, are elevated in people with pancreatic cancer. However, blood tests don’t allow for early detection of pancreatic cancer , because these levels may not rise until pancreatic cancer is advanced, if at all.
