What does my elevated CA-19 pancreatic cancer biomarker suggest?

Question

Hello doctor,

I have a question regarding the significance of an elevated CA-19 tumor marker. I recently had one, and that came back as 43 (per the laboratory, it should have been under 34). I do not have cancer, and I am wondering what else could cause this elevation.

Please help.

Hi,

Welcome to icliniq.com.

CA 19-9, also known as cancer antigen, serves as a tumor marker; however, it may also be elevated in healthy individuals. Elevations can occur in benign conditions such as pancreatitis, cirrhosis, thyroid disorders, and inflammatory bowel disease. Additionally, it may be elevated in various gastrointestinal cancers, including gastric cancer, pancreatic cancer, and colorectal cancer. If you are asymptomatic, meaning you have no history of weight loss or anorexia, there is no cause for concern. Conversely, if you experience concerning symptoms such as significant weight loss and anorexia, an evaluation is necessary. Recommended investigations include

CBC (complete blood count).
LFT (liver function test).
Abdominal USG (ultrasonography).

I hope this information helps you.

Feel free to ask further queries.

Thank you.

Hi,

Welcome back to icliniq.com.

A history of ulcers, gastritis, and reduced lung function does not cause elevation of CA 19-9.
