Cancer (Definition)

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

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.

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.

It depend: 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
good luck

Can diverticulosis (not itis) be mistaken for colon cancer on CT scan? PCP says no. No referal for other tests.

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

Can I be screened for colon cancer with a CT scan instead of a colonoscopy?

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 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

Why would a oncologist say "possible" peritoneal disease in a person with metastic colon cancer but the ct report has no Mention of peritonial?

Why would a oncologist say "possible" peritoneal disease in a person with metastic colon cancer but the ct report has no Mention of peritonial?

Not inconsistent: Peritoneal disease from metastatic colon cancer may affect the peritoneal lining in a thin layer, too thin for the resolution of a CT scan. In other words the CT may not be able to detect peritoneal disease. ...Read more

Metastic colon cancer. Ct scan showed disease stable after 3 chemo rounds. Largest liver met 8 cm. Bilirubin was 12, 19, 12, 33, 51, now 74. What can this be?

Metastic colon cancer. Ct scan showed disease stable after 3 chemo rounds. Largest liver met 8 cm. Bilirubin was 12, 19, 12, 33, 51, now 74. What can this be?

Hyperbili: If jaundiced, intrahepatic (liver caused) levels of bilirubin are likely here. One cause is hepatitis, possibly from chemo, or from the met. In some cases, high bilirubin in adults may be caused by blockages in the bile ducts, depending on where the met is. Symptoms include digestive distress and pain in the abdomen, hard to distinguish from chemo caused side effects. Talk to your cancer doctor. ...Read more

On chemo for metastic colon cancer. Ct scan coming up - says Neck, thorax, abdomen and pelvis. Is neck usually scanned?

On chemo for metastic colon cancer. Ct scan coming up - says Neck, thorax, abdomen and pelvis. Is neck usually scanned?

Yes: There are multiple sites where metastatic colon cancer can appear. While the liver and lung are the most common visceral sites other than lymph nodes in abdomen, spread can occur to the left supraclavicular fossa. Troisier sign is the finding of a hard and enlarged left supraclavicular neck node (Virchow's node). It is a sign of metastatic abdominal malignancy draining the thoracic duct. ...Read more

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.

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.

Unlikely: Given your age it is unlikely. Depending on your symptoms, it could be possible that you may need further evaluation. CT scan are not perfect. What are you worried about? Are you having problems? Why did you have a CT anyway? ...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 more

Why can't a CT scan see colon cancer well? How large would it need to be to be seen?

Why can't a CT scan see colon cancer well? How large would it need to be to be seen?

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

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

Does a CT scan detects colon cancer? Or colonoscopy should be done?

? 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

Do CT scans pick up early stages OR stages of ovarian cancer and colon cancer?

Do CT scans pick up early stages OR stages of ovarian cancer and colon cancer?

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

Computed Tomography (Definition)

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
