Does Colon Cancer Show Up In Blood Tests
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
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!See 2 more doctor answers
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.
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.
Am very curious to know in colon cancer will there be a change in blood count, platelet, rbs & WBC or others may be more or less. Can it be a symptom!
Anemia: Bleeding with resultant decrease in Hgb. And Hct. Is the most prominent change. There is no overall pattern that says "colon cancer"
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?
Then it is too late: Early intestinal and colon cancers (GI) are asymtamatic, WBC not useful, tumor markers like cea is mostly used for follow up for a recurrence of disease. Besides awareness only way for early detection is visit to your doctor, stool for occult blood, and endoscopy to achive the cure.See 2 more doctor answers
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.See 1 more doctor answer
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.See 1 more doctor answer
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.See 1 more doctor answer
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%).

My blood work shows high mpv and low ferritin what could This be? Can low ferritin be colon cancer? And high MPV I read can mean risk of stroke
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
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.See 3 more doctor answers
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.
