What does a tumor marker tell you?

What is a good tumor marker number?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
Can tumor markers be elevated without cancer?
Tumor markers are substances found in the blood. Tumor marker levels may be higher when there is cancer in the body. They are not very “specific,” meaning non-cancer health issues can also cause these levels to be higher. They must be used along with radiology tests and exams by your healthcare provider.
What makes a good tumor marker?
Although the characteristics of an ideal tumor marker depend to some degree on the classification and application of the marker, the general properties of such an ideal tumor marker include (1) specific production by premalignant or malignant tissue early in the progression of disease; (2) produced at detectable levels …
What happens if tumor markers are high?

How reliable are tumor markers?

What is a bad CA 125 level?
The tumor marker Ca 125 is a prognostic factor. Levels around 100 U/l are indicative of a bad prognosis.
Can stress cause tumor markers to rise?
The study, which followed 96 patients with chronic lymphocytic leukemia (CLL), found that those who felt more stress and anxiety about about their condition also had a higher volume of cancer cells in their blood and higher blood levels of markers for advanced disease.
Can tumor markers be wrong?
There’s a chance that a tumor marker test can give a “false positive.” That means the results suggest a person has cancer or that the cancer is growing, even when it’s not. A tumor marker can also give a “false negative,” which means the results suggest a person doesn’t have cancer when they actually do.
What is a high tumor marker number for pancreatic cancer?
