Abdominal cat scan show colon cancer?

Abdominal cat scan show colon cancer?

Unreliable: Specialized cts that are designed to identify colon cancers (ct colonography) are available, but require a specific bowel prep and regimen to be effective. Routine ct scans will miss many small colon cancers that colonoscopy will find--colonoscopy remains the gold-standard. ...Read more

Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.

Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.

Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read more

Can i relax about cancer?Urq disc.&occ floating stool.Normal blood/stool tests, CT scan, colonoscopy, ultrasound and hida scan, endoscopy=gerd/gastritis

Can i relax about cancer?Urq disc.&occ floating stool.Normal blood/stool tests, CT scan, colonoscopy, ultrasound and hida scan, endoscopy=gerd/gastritis

I'd relax for now: Your pain and stool fat changes sound like gall bladder disease, though proven not present. Was the gerd region biopsied? If so and negative, your comprehensive and perhaps more than appropriate workup shows within the limits of present technology, you don't have a detectable cancer. Longstanding gerd can be a pre-cancerous change over the years however and may warrant future follow-up endoscopy. ...Read more

Relax: If all of those tests were normal then you have much higher chances of being injured in a car accident than having an intestinal cancer. Eat a good diet, exercise regularly and enjoy life. ...Read more

Can normal CT scan, stool and blood tests, colonoscopy, gallblader us and hida scan, upper endoscopy (gerd, gastritis) rule out pancreatic cancer?

Can normal CT scan, stool and blood tests, colonoscopy, gallblader us and hida scan, upper endoscopy (gerd, gastritis) rule out pancreatic cancer?

Only one of those : Most of those tests won't tell you anything about pancreas. Only one is ct scan.A perfectly normal ct with IV contrast goes a long way in saying you have a normal pancreas.Mri might give more info but not usually a screening test. ...Read more

Do colonoscopies screen for colon cancer?

Do colonoscopies screen for colon cancer?

Yes.: That is one of the main reasons for colonoscopy. The gastroenterologist usually can see every part of the colon wall and biopsy suspicious lesions. Often this is curative if found early. While not completely true, consider all polyps to be future cancers and most cancers come from polyps. Screening should begin at age 50 unless there is a history to suggest beginning earlier. ...Read more

Is contrast mandatory for abdomen CT scan?

Is contrast mandatory for abdomen CT scan?

No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease. It is often helpful in assessing persons with nonspecific abdominal symptoms as it will better show areas of inflammation, infection, and tumor. ...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. Im 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

Does a normal CT scan exclude pancreatic cancer?

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

Does a pet CT scan replace a colonoscopy?

Does a pet CT scan replace a colonoscopy?

NO!: Pet/ct is an excellent tool for cancer diagnosis and evaluation of therapy, but it does not actually 'look' at the lining of the colon. Often we see activity in the bowel that has been secreted, so it could mask or mimic a tumor. ...Read more
