Why is elevated amylase linked to lung cancer but elevated lipase is not. Are they almost the same type of test?

Why is elevated amylase linked to lung cancer but elevated lipase is not. Are they almost the same type of test?

That's bunk: I don't know where you got the idea that elevated amylase is an indicator of lung cancer, but it's not true. There internet -- including some sites with names that suggest they should be credible -- is full of disinformation about lab testing. One percent of folks have a way-high amylase because of who they are. It means nothing. Stop fretting about this. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
