Can I Be Screened For Colon Cancer With A Ct Scan Instead Of A Colonoscopy
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 moreSee 4 more doctor answers
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
I agree, No: Pet-ct scans are typically used after a diagnosis of cancer to look for other spread of the tumor. If you are looking for an alternative to routine colonoscopy, ct-colonography or virtual colonoscopy is an option. This still involves a bowel prep but requires no sedation. If something is found, you may still need a colonoscopy. Insurance companies are not quite on-board paying for this as yet. ...Read moreSee 5 more doctor answers
I am required to have a pelvic CT scan once a year as follow-up to colorectal cancer treatment. Are double scans without and one with contrast needed?
I had a colon resection for colon cancer and now have a ostomy. I'm having problems and a barium enema shows filing of the cecum. What would cause thi?
I"m confused: If you have a colostomy, and barium is injected into it, the cecum (the first part of the colon in the rlq) should fill. Now, if the barium is injected into your rectal stump and the barium fills, then there's a tract (fistula) between the rectal stump and the cecum, which is not normal. This should be discussed with the operating surgeon. Good luck. ...Read moreSee 1 more doctor answer
I just had a colonoscopy and have been diagnosed with Sigmoid diverticular disease and the doctor also found a 3cms cytic/mucinous lesion in my colon?
Possibly: It depends some on your age and past history. Diverticulitis, an infection of the colon, can sometimes show a lot of thickening on ct scan. That can be hard to tell if the infection caused the swelling, or if a tumor is causing the thickening. It is common to recommend a colonoscopy several weeks after the diverticulitis had healed, if you have not already had one. ...Read moreSee 1 more doctor answer

When screening for small cell lung cancer how big does a mass seen on a CT should be considered for investigation or benign .
THAT'S the question!: The smaller you make the cutoff, the more false-positives you get. Screening has led to a tremendous increase in cases found, but very little overall reduction in lung cancer mortality. Usually it's adenocarcinomas that we find, not small-cells. You decide what it all means. Best wishes. https://www.ncbi.nlm.nih.gov/pubmed/25326638 ...Read more
Would a CT scan with contrast done of my chest to look for a pulmonary embolism also have shown a thoracic and/or abdominal aneurysm?
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 someone had colon cancer a year ago how often should he get a colonoscopy and do all colon and rectal cancers starts from a polyp?
It depends, and yes: If the colon cancer was small, repeat colonoscopy should be done every year. If it was big or obstructed the colon, repeat colonoscopy might be necessary in 3 or 6 months. Ask your oncologist. And yes, all colon carcinomas are believed to start as polyps. ...Read moreSee 1 more doctor answer

I have had ulcerative colitis for 13 years. A recent colonoscopy showed a cancer tumor in the right side of colon. Should i go for a full or partial colon removal ?
Probably : Best is total colon removal because leaving diseased colon in place would keep you at future risk for more colon cancers in the future, and you would need frequent colonoscopy. Can get off colitis medications with surgery. Best to see a colon rectal surgery specialist, maybe at a university, who has extensive experience in ileo-anal pouch surgery. ...Read moreSee 2 more doctor answers
If a pet scan showed a liver met and a node in October for a person with colon cancer , on chemo, can the january scan show further mets?
If i had a clear abdominal & pelvic CT scan with contrast because of blood on stool, am i safe in thinking that it is not colorectal cancer?
Not Yet: Your age and family history play a role in believing there is increased risk or not, but, the final test to be certain would be a colonoscopy. Most colon cancers will start as polyps, a small growth on the wall. These are not well seen on ct scans and can only be ruled out completely with a colonoscopy. ...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
