Can A Blood Test Detect Colon 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
I had a blood test done at my doctor and everything was normal. He said this means I probably don't have Colon cancer. Could I still have colon cancer?
FOBT is screen: Fobt is designed to test for blood in stool. Blood in stool may be due to any bleeding in the GI tract from the gums to the anus; and there are false positives also. If fobt is positive, colonoscopy is generally recommended to look of colon cancer. Fobt per se is not a diagnostic test for cancer, just blood in stool. ...Read more
No: Occult blood in stool suggests a point of bleeding from area near appendix across the colon to the rectum. This could be AV malformation, bleeding polyp, tumor, hemmorhoid or fissure. When blood is detected it has to be defined as to origin. Occassionally colonoscopy will reveal a lesion. Newer stool tests for tumor protein more accurate. ...Read more
I have stage 2 colon cancer and just had a colectomy the oncologist is performing an expensive blood test to see next steps what is this test?
Just ask: May be a CEA level. This is a marker commonly used to follow colorectal cancer patients to indicate a possible recurrence. In sure your oncologist would be happy to explain it to you. All you have to do is ask. Best if luck. Hope this helps! ...Read more
Depends: A blood count may show anemia than can in turn be traced to a cancer anywhere in the GI tract. Also, if the cancer is advanced, tumor markers or liver enzyme tests may be abnormal. As a rule, blood tests are not good screening methods for cancer, it's mostly luck if they find cancer early. Good question, by the way. ...Read more
Does a intestinal or colon cancer show in a blood test thru the WBC? And if there is no bleeding is it possible to be cancer?
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
Worried I might have colon cancer due to change of bowel habbit. My habbit return to normal for a few weeks then go of cycle then return back to normal. Never a persistent change. Been diagnosed with ibs after full blood test came back clear?
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
19, male having diarrhea right after normal stool, watery, blood test fine, no blood or constipation, can it be colon cancer I'm scared!!!
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
A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?
No, but...: But very suspicious for colon cancer. If your friend is similar in age to yourself a mass in the colon on ct scan is cancer until proven otherwise. And CEA levels can go up for other reasons but, given the mass, they would strongly favor cancer. But to answer your question "no"... They are not definitive. You would need a piece of the mass under a microscope to prove definitively its cancer. ...Read more
Do I need CT scan or only blood test for stage 2 colon cancer during my follow up every 3 month for the first year? (no chemo after surgery)
Probably Blood test: You did not have chemotherapy, you do not have lymph node spread in you stage, curative resection was done, you CEA levels will be normal, end of the yea rwill elide, pet scan is a better modality to detect metastasis. You very good chance of being cured but require colonoscopic examinations. ...Read more
1 Morning stool test done.2-3 pus cells. SGOT 62, No blood. Blood test-mild eosinophilia. I have lipomas in my body. Sonography normal. Colon cancer, lipoma?
Guaiacs-: Are actually tests of thin films of stool to discern if there is hidden blood beneath visiblity, so-called "occult blood". It is a great screen, that if positive leads to a closer, less comfortable, more expensive test: colonoscopy. After 50, you get one per decade without occult blood in stool! ...Read more
Establishes baseline: You will almost certainly have normal liver functions, blood counts, and CEA at present, but these will be monitored into the future. Any change can be an early sign of cancer recurrence, so continue to get checkups! I have had many patients who neglected their cancer follow up and died as a result. ...Read more
How accurately will a fecal test find early stage colon cancer? The one that looks for cancer blood markers. Please help!! Approximate percentage.
Pretty low: Conventional assessment of colorectal cancer (CRC) risk largely involves detection of non-dysplastic adenomatous polyps. Standardized sensitivity was 48.2%, for CRC stages I-IV, values were 35.0%, 63.0%, 46.0% and 77.4%, respectively. Specificity was 91.5%. Sensitivity for advanced adenomas was low (11.2%).

IFOBT test Dec 2014, no occult blood. April 2nd, 2015 minor rectal bleeding, stop 1 day after. April 17th, 2015 started again. I'm 22. Colon cancer?
Had red blood, black stool 3 weeks ago for 3 days. Had hemiglobin and occult test 2 days ago and all normal. This does mean I have no colon cancer?
GI consult, EGD: Limited data available as reported. Colon cancer is rare at such an young age. Bright red blood usually from lower GI tract, or hemorrhoids, fissure etc. However black stoll is concerning for upper GI bleed. Need a GI/Gastroenterology evaluation, EGD/upper endoscopy, H Pylori testing, Upper GI series etc. Contact PCP for GI referral. Go to a health tap doctor for a formal consult with more details ...Read more
Can chemo for colon cancer lead to painful urination (blood tests ruled out uti)? And advice to treat the pain?
Best is: To discuss with your oncologist regarding any known side effects of the chemo drugs being used. Pain could be related to your prior colon surgery also so a meeting with the surgeon would be reasonable as well. With no more information it is difficult to give you any more detailed answer. ...Read more
28 yo. Colon cancer fear. No family hist. Ibs diagnosis. Have had tiny specks of blood on tp. Doc said hemmroids. Negative occult test. Do you agree?
Too young for it!: Colon care is uncommon under the age of 50 years, so you should not live under this fear when you are so young. The fact that your doctor has checked you and found hemorrhoids as the cause of your questionable bleeding. Once you get to the age of 45-50 years. Screening with Colonoscopy would be the best security to avoid any fear of this Cancer which is easily detectable and preventable. ...Read more
None: Blood in an ostomy punch can be many things. Is it a colostomy or ileostomy? Why was the surgery done, history cancer or diverticulitis or colitis? How long ago was the ostomy surgery? Bleeding does indicate need for a doctor evaluation. Can be ostomy appliance irritation, colitis, etc. There is no cancer staging associated with intestinal bleeding. ...Read more
Not sure: Depending on your treatment history and related health problems, this has a higher probability of being very serious. Please call your oncologist now or proceed to the ER (bring any advanced directives information with you). ...Read more
I just moved my bowels and it was really hard coming out I saw a streak of blood. Worried its colon cancer?
Probably not cancer: Blood streaking on a hard bm is more likely related to the local trauma of passing stool. Blood mixed inside stool is much more concerning. I would recommend a bowel program using a high fiber diet and a diet supplement like Benifiber 3-4 times a week. When stools are no longer hard, if you still see blood, or if there is a family history of colon cancer then you should have a colonoscopy ...Read more
My dad had colon cancer. I'm 21male. I had bright to Maroon colored blood when I wipe & some in toilet. It first happened 2months ago and has returned?
Not Ca: The presence of colon cancer based for the most part on Weinbergs 3 hit theory where unless one has a congenital form of polyposis it takes three separate events over many years to induce cancer. Maroon stools suggest a bleeding problem which could be related to vascular malformation or internal hemorrhoid. Cancer as a cause at age 20 rare. If problem persists then colonoscopy indicated. ...Read more
