Colon Cancer On Ct With Oral Contrast
Can you have symptomatic colon cancer for five years without showing on ct scans (oral no iv contrast)? Have had five ct in past 5 years
Colon CA CT on show?: 41 F Asks: Can you have symptomatic colon cancer for five years without showing on ct scans (oral no iv contrast)? Have had five ct in past 5 years. ANS: CT not so good for colon cancer detection. What are symptoms for 5 years? This would be unusual as colon CA usually does not cause symptoms other than bleeding or obstruction. Unless it is also in liver now. That should show up on CT eventually. ...Read more
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
Are CT scans with oral contrast useless for see colon cancer. My doc has ordered multiple over last 3 years, all clean, but hearing they are useless??
Ct: They are helpful but you need to have a colonosopy if there there is a concern ...Read more
Chance of developing colon cancer 20 months after colonoscopy removal 5mm polyp removed. Having ct scan with and without contrast for left quad pain?
If the colonoscopy was done properly, you are very unlikely to have colon cancer 20 months after the procedure.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more
It can sometimes: Unfortunately, ct scans are not very good at finding small polyps like a colonoscopy does. The scan will usually only pick up larger lesions. The endoscopy has an additional benefit of allowing small polyps to be biopsied or removed. Polyps tend to grow to become cancer, so they should be removed if possible. Ct scan, won't allow treatment at same time, and thus, is not as good a test for colon ca. ...Read more
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 more
A recent CT scan with contrast revealed two cysts on pancreas. What does this mean? Previous colon cancer and has esld. Also 6mm mass on liver.
Needs attention: Needs work up. Most of the pancreatic tumors are solid but cysadenoma, cystadeno carcinoma will present as cystic lesions need biopsy of these lesions to make sure they are not malignant also liver lesion. If pancreatic lesions are benign could be a candidate for liver transplantation for end stage liver disease (esld). ...Read more
Can Diveticulosis (not itis) be mistaken for colon cancer on CT scan? Had sigmoidoscopy to 35 CM and 4 CT scans over past three years.
Can diverticulosis (not itis) be mistaken for colon cancer on CT scan? PCP says no. No referal for other tests.
Possible but rare: Yes diverticulosis is benign, has distinct appearance from CA on CT for a trained radiologist will read as accurate as reading finger prints, some times in between diverticula the wall may be thickened, may have mucosal overgrowth will mimic a early cancer, then colonoscopy indicated, at 39 cancer is not common but age is not exception for CA, ask again for referral. ...Read more
Not Designed for it:
Not what a ct scan is designed to do.
Usually colon cancer will not be clearly evident on ct until it is at stage iii or stage IV level, since it has to anatomically change the colon to be evident on ct. To get that level of change, it needs to be at minimum a locally advanced tumor.
Every once in a while it may be evident at the stage ii point, but very low sensitivity. ...Read more
? Early detection tes: CT scan is not a good Test for early detection of Colon Cancer, so Colonoscopy is the preferred test because it accomplishes 2 objectives...detect polyps/precursors of colon cancer and remove them at the same time which eliminates the risk of Polyps changing into cancer. If you have difficulty with having Colonoscopy, then you should ask your doctor to suggest some alternative tests for checking. ...Read more
Yes/No: For early detection of Cancer, there are well defined screening guidelines which your primary care physician can share with you and guide you. For Colon cancer CT scan is not a good screening test. Instead Colonoscopy is the best test, but it is to be done> 40 years of age unless you have any symptoms like rectal bleeding or abdominal pain. Best thing you can do is to have an annual Physical exam. ...Read more
She is 59sept end 2013 we came to know tht she is having colon cancer stage 3.Then 6cchemos were given n in CT no improvement. Cetuximab goi survival?
Sometimes: Ct colography is never meant to replace a colonoscopy. At high volumn centers, the detection sensitivity of ct exam is indeed comparable to colonoscopy but you need to know the rate of detection of your imaging facility. Bowel prep is required for both procedures - no way around the unpleasant process. Beware that there is significant radiation exposure with the exam. ...Read more
Complicated: Measurement of lesions at CT is not a trivial task. Measurement in the axial plane in two dimensions may not reflect the volume of the lesion. The measurement is affected by slice thickness and window and level settings. RECIST 1.1 is a standard for tumor measurement, but it seems outdated with modern CT. Development of new lung lesions in high risk colon ca is bad, size willnot affect therapy. ...Read more
How reliable is a ab CT scan for colon cancer? Had 3, what percentage of cancers are missed in a CT scan? Trying to find stats.
My CT scan said my bowel is unremarkable. Could something be wrong with my colon? Like colon cancer? Even if my CT said my bowel is normal.
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
How fast does colon cancer grow. CT Scans 2 1/2 years apart both negative. Would there have been some change by this point? Pcp says IBS.
First CT scan is not the best way to discover or screen or rule out colon cancer so negative CT scan does not mean anything as far as colon cancer concern colonoscopy is the best way to screen colon cancer
you are kind of young for colon cancer most likely your colon problems are caused by something else like IBS
thank you for using health tap ...Read more
How likely is colon cancer in 31 year old? Doc said if CT Normal for RUQ pain then colonoscopy next. Is this necessary? No other symptoms
Perhaps not?: Generally speaking, a 31 year old patient with RUQ pain is unlikely to need a colonoscopy, especially if a CT is normal. It would be rare indeed for colon cancer to be causing these symptoms at your age. I assume you've had a normal abdominal ultrasound. If you haven't had an ultrasound that would be the first test to do before a CT. An online consultation at Health Tap might be helpful. ...Read more
Colon cancer pt. Old ct- nodule on left adrenal gland. (was not met). New ct- new adrenal nodule. Are these the same or diffetent ones, ?
Must compare CT's: The best way to tell if these are the same nodule or if this is a new nodule would be to have the radiologist or your oncologist compare the CT's side-by-side. It may be obvious that they are or are not the same nodule. If it is not obvious, then further testing may be necessary, perhaps even a biopsy of the nodule if it is worrisome. Good luck. ...Read more
Chance that 4 CT scans over 2 1/2 years would all miss sympotomatic colon cancer (narrow stool, occasion blood), also sigmoidscope to 35 cm.
Fairly high risk: CT scans are NOT good tools for looking inside the bowel. Endoscopy is the preferred tool, but a sigmoidoscopy, at its best, misses looking at half the colon. A look to merely 35 cm has missed about 85-90% of the colon. The usual method to evaluate the colon is a complete colonoscopy. ...Read more
Does apple core stricture with mass and few lymph nodes on ct always mean a colon cancer diagnosis or other possible differential diagnosis?
Likely: But you need a biopsy. Nothing is for sure ...Read more
Why would a oncologist say "possible" peritoneal disease in a person with metastic colon cancer but the ct report has no Mention of peritonial?
Would symptomatic colon cancer be missed on 3 separate CT scans? I am only 37 but have had narrow stools and small amounts of blood for past year.
Is it normal for 27 yr old f to have diverticular disease? CT shows several diverticular and remarkably thickened bowel. Could it also be colon Cancer
Could be: Diverticular disease is seen in older patients ie over 60, but I have seen it in younger people. One of the theories on why people get diverticuli, or tiny pouches, in the colon, is the low fiber, high fat diet in the U.S. There may also be an inherited aspect. Thickened wall of the colon and diverticuli aren't associated with cancer, but it's reasonable to get a colonoscopy--talk to your doctor. ...Read more
No: A CAT scan is used to visually define the extent of metastatic colon cancer in the liver should metastasis be present. Liver failure is a condition measured by functional abnormalities that occur within the liver usually due to parenchymal damage such as inflammation from hepatitis. Here one measures serum enzymes and the presence of elevated alkaline phosphatase and bilirubin in serum. ...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
