Will an abdominal MRI show the colon if colon cancer is present? What about the rectum?

Will an abdominal MRI show the colon if colon cancer is present? What about the rectum?

Not best test.: While abdominal MRI can show signal changes as a result of colon cancer, if the tumor / polyp is small, or in a fold, then there's a high probability of missing it. CT colonography is a better test, but has limitations. The BEST test is a colonoscopy (by an experienced Gastroenterologist). In fact, colonoscopy is used to SCREEN for colon cancer in high-risk populations. TTYD or use HealthTap Prime ...Read more

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

Having persistent neck pain and headache for 6 months now. Negative results of brain & cervical mri and emg ncv. Possibility of colon cancer?

Having persistent neck pain and headache for 6 months now. Negative results of brain & cervical mri and emg ncv. Possibility of colon cancer?

Unrelated: Metastasis from colon cancer would have shown up on the MRI. I would ask your doctor if you have muscular neck pain that is also felt in the muscles of the head or if you have a chronic headache that seems to radiate down into the neck. You cannot have both. The two are treated differently. ...Read more

If a scope shows that I have colon cancer after 6 months of low iron and other symptoms, what are my chances of survival if I've had it for that long?

If a scope shows that I have colon cancer after 6 months of low iron and other symptoms, what are my chances of survival if I've had it for that long?

DEPENDS: The prognosis for colon cancer does not depend on the length of time that you have had symptoms. It does depend on size and depth of the tumor, if it has spread to lymph nodes or other places and genetics of the cancer itself. Some patients have very advanced tumors with no symptoms while some have symptoms and have a very curable cancer. ...Read more

Can KUB show polyps and/or colon cancer?

Can KUB show polyps and/or colon cancer?

Not usually: Polyps and Colin cancer are soft tissue conditions, and do do not typically show up on X-ray. The main exceptions to this are if they are calcified, if they are causing a bowel obstruction (you can diagnose the obstruction but not the cancer), or if contrast is given in the GI tract first (known as a upper or lower GI series). Ct scan is the radiologic test of choice, colonoscopy shows as wel ...Read more

If someone got colon cancer and never got treatment of any sort, how long before they would show signs of being sick and how long would they live for?

If someone got colon cancer and never got treatment of any sort, how long before they would show signs of being sick and how long would they live for?

A long time,,: This disease takes a while to develop like 20-30 years, unless it's associated with one of the polyp syndromes that cause it to appear much earlier. Usually it presents in the sixth decade of life (50-60) as fatigue and or change in bowel habits and abdominal discomfort. By this time it's usually advanced and 5 year survival is compromised. That's why colonoscopy is done for polyps at 50. ...Read more

3 cycles of chemotherapy so far for metastic colon cancer shows therapy working, if 2 cycles are missed due to ill health, will cancer start growing agsin?

3 cycles of chemotherapy so far for metastic colon cancer shows therapy working, if 2 cycles are missed due to ill health, will cancer start growing agsin?

No: If 3 cycles of chemo given and well tolerated, evaluation might show stability or regression if drugs working. If missing 2 cycles, this will not allow further regression while off medication, but if resumed a further response may be defined. Most combo drugs for colon cancer may show a termporary response but not cure. The newer combinations with Immunochemotherapy more effective. ...Read more

Don't know..: What web sites you are looking at, but seeing something on the internet that is not produced by a well recognized source is not likely to be useful to you.

Iron deficiency: Not to worry. At your age, unless it runs in the family, there is extremely low chance this is colon cancer. Likely what your tests say is that you just have a little iron deficiency. This is very common to see in young healthy females as a result of menstrual periods and not enough dietary iron intake. The elevated MPV is likely due to secondary effects of the iron deficiency. Keep your follow up ...Read more

Can a CT on abdomen with contrast show colon cancer if there are present symtoms?

Not always: Unless the cancer lesion is fairly large, colon cancer is not commonly seen on a ct scan. Colonoscopy is the best test for colon cancer. Some places have the ability to perform a specialized ct colonography x-ray exam that may see lesions about 1 cm or larger. ...Read more

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?

Hopefully not: As with any cancer, progression of disease is always possible and the purpose of surveillance imaging is to assess for the effectiveness of the treatment. Hopefully, the next scans will show improvements and not additional mets as the chemotherapy impact has begun. ...Read more

Would a cat scan a month ago show advanced colon cancer? Been having weakness weight loss last few weeks and I hear you don't get symptoms till advnc

Depends: It depends on what you mean by advanced. If you mean spread to other organs, usually it will. If you mean advanced within the colon itself. Not unless it was really large. I've noticed that you seem to be asking a lot about colon cancer. If you have had a clear colonsocopy, you should be in the clear. ...Read more

Doctor said to my dad he have colon cancer but the biopsy result was ok it show that is just polip. His blood test was ok aswell. What we should do now?

Repeat colonoscopy: Unless the pathology report comes back on the polyp as showing malignancy, he will need to have a follow-up colonoscopy to look for new polyps in the future (1-3 years). The timing will depend on risk factors, such as a history of ulcerative colitis, strong family history, completeness of colonoscopy, biopsy findings. If the pathology shows cancer, he should see a colorectal or general surgeon. ...Read more

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 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 more

Wouldn't a blood test or cat scan show stomach or colon cancer.?

Wouldn't a blood test or cat scan show stomach or colon cancer.?

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 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

Please clarify...: Are you asking about a source of vaginal bleeding, bleeding per rectum, or are you not sure of the site of bleeding? At age 51, you certainly qualify for and should undergo a screening colon exam (if you have not already accomplished same within the intervals established by medical convention). ...Read more

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

My sister is on chemotherapy (folfox for metastatic colon cancer). Recent blood test shows high WBC (14, 000) and platelets (429). Is this okay?

No worries.: High WBC can be due to many causes: infection, stress, steroid use, dehydration, or the use of growth factor (such as neupogen). If there is no evidence of infection, then there is nothing to worry about. High platelet count is not uncommon since it is a body's reaction to stress of any cause (platelet is an acute phase reactant). Again, nothing to worry about. All the best, hk. ...Read more

Would abd ultrasound and full blood count show something is wrong possibly colon cancer? No blood visible only loose stool. Diagnosed with ibs.

Loose stool: At your age colon cancer would be very rare. Abd US and full blood count are not the best tests to screen for colon cancer. A colonoscopy would be the better test. If your tests thus far are normal but still have symptoms, I would see your doctor for further testing. Colonoscopy would be the best test as I stated before if all other tests were normal. ...Read more
