Should be checked: Thin stools can be a sign of rectal, not colon cancer. "Pencil" stools are caused by the cancer in the distal rectum or anus causing a severe narrowing which allows only a thin stool to pass. If the thin stools continue, you should see you're PCP and may need a colonoscopy. ...Read more

Whoa: Forgive me for this. You list yourself as having colon cancer. This will only narrow the caliber of your stool if it's still present. Are you inoperable? Is this a self-diagnosis unconfirmed by a competent physician? The bottom line is that we can't answer your question without more clinical information, and ultimately you need to find a physician whom you trust, cancer or no. ...Read more

At what point do I need to worry about colon cancer? I've had pencil thin stool for a week now and can't completely empty my bowels.

At what point do I need to worry about colon cancer? I've had pencil thin stool for a week now and can't completely empty my bowels.

Unlikely at your age: It would be very unlikely for someone of your age to have colon cancer, unless there's a strong family history that would suggest a genetic predisposition for such. However, with these pencil-thin stools, you may have an infection or inflammation within the colon which needs identification and treatment. A CT scan and colonoscopy would be in order to investigate this. ...Read more

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

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

Needs colonoscopy: Even if he had no problems we are supposed to start routine colorectal cancer screening at age 50. The best care practice to do so remains colonoscopy although there are many other tests that are also done such as checking stool for blood, barium enema, sigmoidoscopy to name a few. If he has already had one it depends when. If it was more than 1-2 years ago it can be repeated if symptoms arise ...Read more

So rare: You are more likely to get hit by a bus today than have colon cancer at your age. I'm not sure what symptoms other than "no blood" you refer to, as most colon cancers have no symptoms. If you are having abdominal pains, fullness, nausea, etc - then you should see doctor as there are literally hundreds of conditions other than cancer that could cause symptoms in abdomen. ...Read more
