Ct Scan Stomach 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
Can a CT scan and MR miss stomach cancer? I am worring about my upcming endoscopy finding something. Please help.
Possibly: Some forms of stomach cancer show up on ct scans others do not. Sometimes the doctor has to go down through your mouth and esophagus and look directly into your stomach and take biopsies of your stomach to find other kinds of cancer. Certain kinds can b e very difficult to diagnose as they can hide in the lining and not form large tumors that would be visible on a ct scan. ...Read moreSee 3 more doctor answers
Sometimes. : It depends on many factors, the size of the cancer, the organ it involves, technical factors with the study, etc. There are many variables. Remember each cancer starts as a single cell, so we can never completely exclude the diagnosis even when a ct is completely normal. Pet/ct can show cancers that are virtually impossible to see on ct, even with contrast. ...Read moreSee 1 more doctor answer
Not usually one: Radiation dose from ct is about 100 times chest x-ray. However the exact number of scans to induce cancer is not precisely known.If ct is necessary for diagnosis it is very accurate tool. Most institutions have reduced amount of exposure in recent years. If same diagnosis can be made with mr or ultrasound, non ionizing radiation, they should be chosen.Certain medical problems ct is necessary. ...Read more
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 moreSee 3 more doctor answers

Worried about cancer. Dr. Recommended an abdomen pelvis CT scan with contrast because of lower right pain that came up clean. It was a 10msv dose. Is 10msv a lot and should I be worried? Thanks
CT Scan Findings: Ct scan is not the best study to detect colon cancer or ulcers. Although a ct scan may show a large sized colon cancer, the sensitivity of this is greatly reduced without the administration of oral contrast. Ulcers are typically not seen on ct scan. The best diagnostic study for both of these would be an endoscopy and colonoscopy. ...Read moreSee 1 more doctor answer
Not if early: A ct is not sensitive enough to find very small colon growths. There is a blood test the cea that is high in some cancers, but usually only when quite advanced and not specific to colon cancer. Now, a ct might suggest a colon cancer, however, colonoscopy is considered the gold standard for detecting colon growths. There is research into high definition ct but it is not considered a standard. ...Read moreSee 1 more doctor answer
In the last year had lots of mri, cat scan, xray ultrasounds of my chest & stomach & my head & knee how much of a risk do I have from getting cancer?
Minimal: First, MRI and ultrasound do not increase risk of cancer. These do not involve exposure to any radiation. CT imaging and to a lesser extent plain x-rays carry a very small risk, which might become significant to an individual if tests are repeated frequently over many years. It is estimated that a single CT of the abdomen might increase cancer risk by 0.05%. ...Read more
Not necessarily: If the scan was done with oral and IV contrast material, it is more likely the cancer could be seen on ct; if no contrast was used for the scan, it is unlikely cancer could be seen. Some stomach cancers are flat and not bulky; the flat ones may not be demonstrable on ct. Also, very small cancers may no be seen on ct, the best way to see stomach ca is with an upper endoscopy. ...Read moreSee 1 more doctor answer
Not unless it : Is advanced case. Gastric cancer, as other GI malignancies, start in the inner lining of a hollow organ, so in its early stages can be difficult to visualize on ct scan. By the time gastric, and other GI cancers, become visible on ct, they are far advanced. So don't rely on negative ct scan to exclude the possibility of stomach or colon tumors. ...Read more
I have stomach issues, scared I have stomach cancer. I've had upper gi-clear & a CT scan of abdomen- was clear- what r chances I have stomach cancer?
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
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
