Colon Cancer 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
I had a polyp removed from my sigmoid at age 20 and it was benign. No direct family history of colon cancer. What tests should be done ongoing?
Typically: It depends on type of polyp found/ removed and why scoped. Consider full colonoscopy if there was one, there could be more. Typically a colonoscopy every 5 yrs is indicated with a family history of colon cancer or a personal hx of polyp or cancer (at a minimum). Consult a GI specialist for further management. ...Read moreSee 1 more doctor answer
Probably not: By all tests I assure that you are referring to blood samples as well as colonoscopy. If the blood tests are neg. they have no diagnostic value at the present time. Most are CA or carbohydrate antibodies with about a 50-60 % validity in dx. Colonoscopy would, at the present time be the best way to assure the bowel is free from CA. If that test was neg. then at least for 5 yrs. you are fine. ...Read more
Is it recommended to get a colonoscopy at age 43 if there is a family history of colon cancer? What other tests are needed at this age?
10 years before diag: A basic guideline is that in the case of a potentially inherited cancer trait, that we start screening 10 years before the presentation of a first degree relative, i.e. Parent or sibling. If the relative was diagnosed with colon cancer at age 53, we consider beginning screening tests at 43. Otherwise begin screenings as age appropriate, colonoscopy age 50, mammo age 40. ...Read moreSee 1 more doctor answer

Testing for colon cancer? Are there any tests besides the colonoscopy? I really don’t want to have to use those colon cleaning laxatives. I had to once before and felt really sick from them. Isn’t there another test?
There : There are actually two separate questions here. The first is whether there area alternative tests besides colonoscopy. There are other tests; but each one has limits. Testing stool for blood can identify cancers; but is not a good preventative test. The real goal is to find polyps before they become malignant. Work is underway on tests that try to analyze dna found in stool to look for markers of abnormal growths. It is an exciting area; but the current tests are not accurate enough and far too expensive. The alternative to colonoscopy that is designed to find polyps without insertion of a colonoscope is ct colography or "virtual colonoscopy". However, it also requires a preparation; and is both more uncomfortable and less accurate than the colonoscopy. The second question you asked deals with the preparation itself. Talk to your physician. There are several newer preparations that entail much smaller volumes of preparation liquid over longer times than we used to use in the past. Most people find it easy and very tolerable. I know i did for my exams. ...Read moreSee 1 more doctor answer
How is colon cancer diagnosed? What is the prognosis? What tests are used to determine the different stages of colon cancer
Biopsy: Colon cancer is diagnosed by a biopsy sample during colonoscopy. Pathology helps determined the stage after surgical removal of the cancer. Ranges from best stage 1 with small early cancer, to most advanced stage 4 when cancer has spread to other organs. Sometimes a ct scan or pet scan may be used to see if the cancer has spread to other sites. ...Read more

The test may also be helpful in determining those patients with stage ii or iii cancer who may benefit from chemotherapy. ...Read moreSee 2 more doctor answers

What do you suggest if my CEA test was a 3. should I do something else . I had colon cancer in 1997?
Chill: Three is normal, my friend. Colon cancer would be unlikely to relapse after 15 years plus. Of course, you could develop another colon cancer so you need to keep your follow ups with your oncologist and get your colonoscopies religiously. Live healthy and if you smoke, quit (that will increase the CEA, by the way). ...Read more
Many options: The gold standard is colonoscopy, which is performed under sedation. Other alternatives include barium enema, ct colonography ("virtual colonoscopy"), flexible sigmoidoscopy, and/or checking for blood in bowel movements (hemoccult test). I recommend colonoscopy for all my patients at age 50 (or earlier, if they have a family history). ...Read moreSee 1 more doctor answer

Test for blood in BM: The fobt tests for blood in the stool. Test is performed on spontaneously voided stool on three separate occasions. Presence of blood in any of the samples is a "positive" test.

First i would: Repeat the cea, if higher need to discuss with your oncologist or a colorectal surgeon or GI doctor to begin workup of recurrent colon cancer. Cea of 3 is not abnormal. You should have been getting colonoscopies regularly since your original diagnosis. Pet/ct scans may be necessary. But if cea is 3 on repeat i would not be concerned. Just stay on 5year colonoscopy schedule. ...Read more
Hi, I'm 21 and have all the symptoms of what possibly can be colon cancer. I want to know what is the best way to test for it. ?
What symptoms?: What exactly are these "typical symptoms"? Colon cancer can cause something as subtle as a change in bowel habit. PLEASE do not diagnose yourself with Dr Google. Rather visit your doctor, tell him your symptoms (NOT what you THINK is the diagnosis), and let him make a diagnosis. He will then refer you to a specialist or schedule more tests if required. ...Read moreSee 1 more doctor answer
