Can A Ct Scan Show Cancer
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
Will a CT scan show ALL cancers? Are there any cancers that may NOT show up on a CT scan? Does it cover all risks of any cancer?
Many kinds could.: The neck is an anatomically complicated region with many internal structures. A ct scan of the neck could show both primary and secondary cancers (tumors that started in the neck and tumors that have spread to the neck from other parts of the body). One primary neck cancer that might be seen on a neck scan is thyroid cancer. Lymphoma is another. Tongue / tonsil / larynx cancers also... ...Read more
I'm 23, male, had CT scan show a lesion of a few millimeters on bladder. No other symptoms. What are the odds this is cancer? What else could this be?
Need cystoscopy. ..: I assumed the reason for having CT was blood in urine or bacterial urinary tract infection. So, thus far, you need a direct look at the whole interior of the bladder to make sure this tiny lesion of few mm is a tumor or a false image (this is possible). For a 23-y-o man, a malignant lesion is not highm but still possible; I have seen a low-grade malignant tumor in a man as young as 18 yrs old. ...Read more
Will a CT scan (no contrast) detect cervical cancer if it's stage 2B or above? I realize a CT can't diagnose cervical cancer, I'm just wondering how likely it is that something would show up on a ct.
When would CT scan cancer effects show up? If I received too much radiation as a result of CT scans, when would the cancer potentially show up? Could I get canncer in 10-20 years because of CT scan radiation?
Delayed, high dose: In general, ct scans do not by themselves cause cancer. You would have to have had dozens upon dozens to risk the development of cancer. Having said that, when radiation induced cancers development, they are usually in the field of radiation, and usually are sarcomas (soft tissue malignancies). Based on your age, you would have to have had hundreds of cts in a short time 15-20 years ago. ...Read more
What is the prognosis when I have stage 3c primary peritoneal cancer, have went through the 6 rounds of chemo and my CT scan shows residual disease?
A CT scan shows mild wall thickening in small bowel (ileum). It was there 10 months ago on other ct. No fluid/other problems seen. Likelihood cancer?
Mother had colonoscopy- they found a small lesion that they believe is cancer. Doing a CT scan next before the remove it? What does the CT show?
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
If pancreatic cancer in body or tail is causing symptoms, would it show up on a iv contrast ct scan?
If I had kidney cancer, would it most likely show up on a CT scan even without contrast dye. They want to do another with dye. All other test neg.
Ct scan shows diverticulitis Gi advised sigmoidoscopy to check narrowing of colon could it be cancer as been told only scoping can confirm difference?
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 small cell lung cancer cause malabsorption through zolinger Ellison syndrome. Would this be a presenting sign of sclc before it shows on ct scan?
Uncommon: Most Zollinger-Ellison / gastrinoma are from islet cell tumors of the foregut. Oat cell carcinoma can produce other paraneoplastic syndromes, famously the anti-nerve cell ones, before being visible on chest ray, but it announces itself fast enough. And what are you going to without a localized tumor? Take out both lungs? Look for some other cause for any suggestive symptoms. Good question Gill. ...Read more
Is it possible that CT scan shows no pleural masses while I have lung cancer and massive effusion?
Unusual but yes.: CT scans have limited resolution. They do NOT see everything. Usually large pleural effusions come from significant disease, but not always cancer. The only way to tell is to have the pleural effusion drained & sent for cytology & other testing (culture). The lab techs can spin down the fluid, isolate cells or bacteria that may be causing it. Talk to a pulmonologist or your primary doc. Good luck! ...Read more
How often do you need to use PET scan or bronchoscope to locate lung cancer because it does not show on CT scan but symptoms tell you to keep looking?
Clinical judgement: This pathologist is underwhelmed with the health or public benefits of intensive screening for tiny lung cancers. I'd hope that if the person is symptomatic, some other investigations are undertaken and the actual cause gets found. ...Read more
I had kidney cancer and now have pain in my right hip area and going down the right side of my bottom CT scan show a lesion in the right medial ilium?
Further testing: More detailed imaging may be helpful and possibly a biopsy of the area to determine the exact cause of pain. In cases of isolated bony metastasis, focused radiation therapy can provide significant relief from pain. Other therapies may be available as well depending on your particular situation, but it is certainly possible that'll none of this is cancer related. Good luck and keep in touch! ...Read more
I was diagnosed with testicular cancer on 7/22/12, removed 7/25/12. Blood work good, CT scan shows 4mm, 6mm, 12mm spot on liver, your thoughts, MRI 10/9?
My dad is 53 years old and in good shape. He was diagnosed with stage 4 secondary liver cancer; the primary is still unknown. He has had a CT scan, an endoscopy, and a colonoscopy done. Will a pet scan show something more?
Small bowel cancer diagnoses is barium xray why it has not replaced by CT scan both need barium drinking but CT show more things?
Barium: Much better for luminal (phenobarbital) lesions, CT better for extraluminal (phenobarbital) lesions. They complement each other ...Read more
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
