Cea blood test levels low but cat scans show more cancer?

Cea blood test levels low but cat scans show more cancer?

Possible: Please note that cea is just another tool we have and as such it is not perfect. Many patients have elevated cea and have no cancer and many others have clinical and x-ray evidence of active cancer and yet their cea is normal. Such tumors just don't produce cea and in those cases, the test is useless. No test is infallible. ...Read more

Do abdominal/pelvic cat scans show ovarian cancer?

Do abdominal/pelvic cat scans show ovarian cancer?

Computed tomography : Can often detect abnormalities consistent with ovarian cancer, but a specific diagnosis with only imaging, except in rare circumstances, is ill advised. The analogy I use is that medical imaging is like showing a stranger a picture of your family reunion. They can distinguish young vs old, boy vs girl, etc, but won't be able to point to uncle bob or cousin sue. Diagnostic pathology is needed. ...Read more

Please advise if it's normal not to get cat scans after breast cancer treatment?

Please advise if it's normal not to get cat scans after breast cancer treatment?

Depends...: ...On many factors. Current standards of care do not recommend scans for patients with low risk for recurrence as they do not improve the overall chances of surviving the cancer (this was proven in at least 2 or 3 clinical studies). Patients with stage 3 cancer often do get scans, especially in the beginning, to do a complete staging. ...Read more

My brother has a pe and a mass on lung with thyroid nodules. Never smoked. He is hospital 5 days INR still 1.1. Cat scan says possiable cancer. How will we know for sure ?

Biopsy: The easiest in this case is to biopsy the thyroid nodules. You don't need to go off the anticoagulant to biopsy a thyroid nodule. The needles that we use is so small that bleeding is not a big concern with thyroid biopsies. ...Read more

What are the chances of false negative mris and cat scans? What are the odds that an MRI and a cat scan would both show no cancer when there really is cancer present? What about the opposite, where they would both should cancer when there really is none?

What are the chances of false negative mris and cat scans? What are the odds that an MRI and a cat scan would both show no cancer when there really is cancer present? What about the opposite, where they would both should cancer when there really is none?

No test is 100%: The sensitivity of MRI and ct scans depends partly on the type of cancer and the location in the body. In general, they can find tumors that are a few millimeters in size which can be 10's of millions of cancer cells. If all scans are negative a patient may be considered in remission, but with cancer it is really only the "test of time" that ensures no microscopic cells are left. ...Read more

Can an abdominal pelvic cat scan screen for colon cancer or see a mass in the rectum?

Can an abdominal pelvic cat scan screen for colon cancer or see a mass in the rectum?

Sometimes: Sometimes a cat scan will be able to see a mass in the colon or rectum but it is not a good test for screening for colorectal cancer. There is a specialized type of ct scan that creates a virtual image of the inside of the colon that is sometimes used when a patient is not a good candidate for a colonoscopy. ...Read more
