The reason is that the test may be falsely normal (false negative) in many cases or abnormally elevated in people who have no cancer (false positive) in others. The main use of CA19-9 is therefore to see whether a pancreatic tumor is secreting it; if that is the case, then the levels should fall when the tumor is treated, and they may rise ...
Andraka talks about his work. Andraka's winning project consisted of a sensor, similar to diabetic test strips, for early-stage pancreatic cancer screening.The sensor, consisting of filter paper coated with single-walled carbon nanotubes and antibodies against human mesothelin, was said to measure the level of mesothelin to test for the presence of cancer in a patient.

[8] Pancreatic cancer is the fifth-most-common cause of death from cancer in the United Kingdom, [19] and the third most-common in the United States. [20]
The technique is highly sensitive for detection of pancreatic cancer (90–95% sensitivity), particularly in patients who are suspected to have a mass or present with jaundice [citation needed]. Its role in staging patients with pancreatic cancer is limited to local metastases; however, in combination with CT scan which provides information on ...
Pancreatic cancer ranks as the third leading cause of cancer-related deaths in the U.S., according to the National Cancer Institute. It is rarely curable and has a five-year survival rate of less ...
