I have urq pain, now bone pain on the right side and get night sweats. Can a CT scan always pick up pancreatic or bile duct cancer?

No test is perfect!: No test is 100 percent accurate. Although a multiphase ct with contrast is a very good test for pancreatic or bile duct cancer, it is not a perfect test. Mri, mrcp and ERCP are all tests that may be useful. Generally, imaging for this problem begins with a ct, with the additional tests based on the ct results, as well as lab tests and other examinations. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Pain up abdomen and back. Dual phase ct nomral. Eus bile duct to ampulla normal. Alt 71 No stones found Worried pancreas. Docs says ibs. Correct?

Pain up abdomen and back. Dual phase ct nomral. Eus bile duct to ampulla normal. Alt 71 No stones found Worried pancreas. Docs says ibs. Correct?

Panc Ca discussion: If there is a VERY strong family history of panc Ca, some might consider dynamic contrast MRI to find TINY lesions. But this is overkill just to exclude a panc. Lesion that would be symptomatic as contrast CT and EUS are really good tests. There can be diagnostic challenges w/ abd. And back pain. Most are benign under 40 yo. An internist will have all your info and can try to put it together. ...Read more

63 year old Male all blood tests normal except Ca19-9=2314. CT scan=enlarged panc. US=no stones. Can it be Pancreatic cancer?

63 year old Male all blood tests normal except Ca19-9=2314. CT scan=enlarged panc. US=no stones. Can it be Pancreatic cancer?

Very suspicious: Hi. Why did your doc measure a CA 19-9? Yes, the result looks very elevated and suspicious for pancreatic CA. However, I can't imagine a radiologist reading an abdominal CT as "enlarged" pancreas. No mass? I don't want to guess with something so potentially serious. Talk with the doc ordering the studies and get a sense for where you're headed. Good luck! ...Read more

Will a contrast dye CT scan always show small gallstones in bile ducts?

Will a contrast dye CT scan always show small gallstones in bile ducts?

No: Contrast does not usually enter the bile ducts or gallbladder except under certain unusual circumstances. Gallstones and bile duct stones can often be seen in a non contrast ct scan, but they will also be detected in a carefully performed ultrasound exam. ...Read more

If pancreatic cancer in body or tail is causing symptoms, would it show up on a iv contrast ct scan?

Yes it would: CT scan of the abdomen is a reliable to test to check for Cancer of the Pancreas. So you do not have to think too much about this as a source of your symptoms. Go see a Gastroenterologist if symptoms persist for more than a week or two. ...Read more

What would a PET scan show that a CT scan may not for a person with pancreatic cancer?

What would a PET scan show that a CT scan may not for a person with pancreatic cancer?

PET in cancer: PET scans are used to detect areas of abnormally increased metabolism, while CT scans only detect areas of differing density or lucency to radiation. So an abnormality like an area of scarred old tumor might look abnormal on CT scan but not have increased metabolism indicating active cancer on PET scan. False positives still occur with both, but they tend to commplement each other. ...Read more

How frequent can be CT-Scans be taken and still be considered safe - esp. Looking at the abdomen? I worry about Pancreatic Cancer even with IBS-C

Additive exposure: Each ct scan is well within the safe limits of radiation exposure, but each one is additive in terms if exposure, making ct scan a poor choice for any life long routine imaging tool. In other words, the effect of radiation exposure doesn't go away over time. IF you really need serial imaging, maybe MRI is a better choice. (Note the IF part) Hope this helps! ...Read more

Cancer: It is not pancreatic cancer unless and until to doctor and the pathology lab confirm you have pancreatic cancer.
If that is the case curative treatment can be performed and you would need other meds.
Hope all goes well. ...Read more

Epigastric pain, back and upper right quad pain for 6 weeks. Pancreas ct scan with contrast normal. Worried about pancreatic cancer. Ct reassuring?

YES: The CT is reassuring however a lesion in your upper GI tract (esophagus/stomach) should be ruled out as well! Ask the Health Care Provider who ordered your CT scan...he/she probably can "take a look" (endoscopy)

Likelyhood of pancreatic cancer in 34yr male with urq disc. Occ. Floating stool? Normal CT scan of abd/pelvis, u.S, blood, enzyme, stool tests normal.

Likelyhood of pancreatic cancer in 34yr male with urq disc. Occ. Floating stool? Normal CT scan of abd/pelvis, u.S, blood, enzyme, stool tests normal.

Floaters are fine: The usual reason for a bowel movement floating is extra trapped gas; this varies with diet, gum-chewing, roughage, how much you talked & swallowed your saliva. When due to fat malabsorption (a much less common explanation) the person is clearly sick; if due to pancreatic cancer you'd be jaundiced. Any further concerns are best discussed with your physician. ...Read more

I'm 34 w urq disc.&occ floating stool. Normal stool tests, CT scan, colonoscopy, u.S, hida scan, endoscopy=gerd/gast. Can I relax about pancreatic cancer?

Yes, you can: You mentioned nothing suspicious for pancreatic cancer. A normal ct scan is encouraging but is not 100% accurate. If there are suspicious symptoms or chances on a ct scan, a normal ca-19.9 (a blood test that is nearly specific for pancreatic cancer) would be reassuring. ...Read more

Should I worry about pancreatic cancer? Urq disc.&occ floating stool. Normal stool tests, CT scan, colonoscopy, u.S., hida scan, endoscopy=gerd/gast. I'm 34

Probably not: It appears that all test are normal except for the egd or endoscopy showing gastritis. Assuming normal blood workup as well, I would say that it is not likely that you have pancreatic cancer. My suggestion is that you sit down with your doctor and discuss all tests results and treatment plan. Good luck! ...Read more

Can pancreatic cancer or cancer in pancreas be detected with CT scan?

Can pancreatic cancer or cancer in pancreas be detected with CT scan?

Often: Ct scan is a very good way to detect pancreatic cancer, but there are a few caveats. One, no test is 100% accurate. Two, some cancers may not be detected on ct scan because of the way the study was performed. Three, some may not be detectable due to small size or location. There may need to be other tests such as ERCP or endoscopic ultrasound. ...Read more

If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?

If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?

Pancreatic cancer: Was the CT tailored for pancreatic mass protocol? If so it is highly accurate for detecting even very small panc masses. If it was a routine CT, the accuracy is still high, but very small tumors may not be seen. MRCP is also not specifically tailored to look for panc mass, so very small lesions may not be seen. No test is 100%, so it is always possible that another test could pick something up. ...Read more

What's better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs?

If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

What test is the best test to look for pancreatic cancer I'm scared? I have abd pain had mri/us/ct only thing it show is gb stones or polyps please help

Imaging studies best: The tests you had are very sensitive for finding pancreatic masses. If they show only stones then that is the likely reason for pain. Pancreatic cancer is rare at your age and stones can commonly cause pain and are far more common in a young woman. Blood test for ca19-9 can be used but is not specific for cancer. ...Read more

gallbladder needs to be removed due to gallstones. A CT scan revealed a 3.5cm solid mass abuts the pancreas. They said no cancer but can't identify?

Requires surveillanc: Any soft tissue mass which is growing can be due to cancer. A biopsy of such a mass is required before we can find out the nature of this mass. I would recommend an interval reevaluation with a repeat CT scan in 2 months time, in order to determine if it is growing in size. If it is not growing over 6 months, it is unlikely to be cancer. A PET scan can give an answer sooner, but it is costly. ...Read more

Are normal cbc, billuprin, amylase and lipase levels, CT scan and qualitative fecal fat test a good indication against pancreatic cancer?

Yes: Pancreatic cancer is most uncommon at your age to begin with (it is not a common cancer in general). Normal blood tests and ct scan should reassure you that pancreatic cancer is not there. ...Read more

Does a normal CT scan exclude pancreatic cancer?

Not entirely: Ct imaging is useful, but pancreatic cancer can be very difficult to visualize on ct. In fact, even in patients with known pancreatic cancer it's not unheard of for the tumor itself to be poorly or incompletely seen. If there's high suspicion, endoscopy and ultrasound are useful tests. ...Read more

What's better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.

CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and CEA can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more


Obstruction (Definition)

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more
