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%).

The blood one. is falling out of favor. The one that looks for just plain blood in the stools is progressively getting NOT recommended. http://www.cancer.org/cancer/colonandrectumcancer/moreinformation/colonandrectumcancerearlydetection/colorectal-cancer-early-detection-screening-tests-used?gclid=Cj0KEQjw75yxBRD78uqEnuG-5vcBEiQAQbaxSCWbKOBG7sFn0Oxe9TefaqMFviZjhCwsTaRfxutRoyIaAmuO8P8HAQ the DNA one is not ready.

Black little dots in stool. Would colon cancer stools be thin one day then be normal the next? I did have blood in stools for two days only last week

Not sure. I am assuming that you do not have a significant family history for colon cancer. Colon cancer can result in thin stools but i would think that they stay that way. Blood in the stool can indicate possible colon tumor(polyp) or cancer but it not very common for patients your age.I would reccomend that you see a dr. To find out the cause of your bleeding.Internal hemorrhiods could be a cause. 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!!!

Don't be scared. Be smart. Go to a doctor and get it sorted out. Probably not colon cancer, but it is a possibility. It is rarely seen in young people such as yourself. We can't give you any more advice than that. You need to be seen, examined and evaluated. It's the only way to ease your mind. Read more...
Relax. Colon cancer doesn't behave this way and is very, very rare in 19 year olds. Diarrhea after a normal BM is not unusual and often depends on diet, anxiety, etc. If it persists, see your primary care provider for an evaluation. Thanks for trusting HealthTap! Read more...
