Imaging with CT. Can observe some cases, but will miss others, so it is not the best, endoscopy, endoscopic ultrasound, and ERCP or mr-cholangiography help, but all require biopsy proof. Next is categorizing for resection, the only successful treatment, and the vessels (sma, smv, portal vein) are the critical facts, as well as nodes, peritoneal and distant sotes of mets.
Hard to tell, good. Abdominal ct with contrast is an effective tool to identify and locate pancreatic cancer. The trouble is most of these lesions have already spread. Patients usually have other symptoms and signs, like pain, jaundice, and abnormal liver function tests which would indicate bile duct obstruction. Clay-colored stools are often seen.
Possibly. There are different types of imaging that may demonstrate a mass, or the effects of a mass or stricture in the ducts of the pancreas. Ct may show a mass, but often a biopsy, which is interpreted by a pathologist, is necessary to confirm a diagnosis of cancer.
Size, detectability. Ct scans will indeed show the mass of a pancreatic cancer once it reaches a certain size, but most cases are advanced by the time the primary tumor is large enough to see on a ct scan. So it isn't a question of "practicality", but one of what the ct is useful for. It can't be relied upon as a screening tool (plus it involves radiation exposure).
If pancreatic cancer was the cause of urq disc in 34yr would it be advanced enough not to be missed on CT scanw contrast? Test normal but still worried
Probably not. Symptomatic pancreatic cancer is usually easy to detect by ct. A normal scan, especially in a 34 year old, makes pancreatic cancer very unlikely. There are, however many other mire common causes of abd pain such as gallbladder disease and ulcers that are not well detected by ct. If pain persists see you physician for additional testing.
Had a pancreas protocol ct. It was clear would this be reassuring for pancreatic cancer? Really worried.
Yes. If no cancer is found on the scan, one can work with his GI specialist if symptoms continue, to see what follow-up care is needed. One can only worry so much about cancer, as we are all here on this planet for only a short while. If a disorder is not detected, worrying too much about an undetectable disorder can lead to a miserable life, due to anxiety. Thus, one must choose to live without worry.
