Question 1

does having pencil thin stool mean i have colon cancer?

Accepted Answer

For how long?: Anybody can pass a thin one from time to time. If this persists for more than a few days, go in and get a rectal from your physician. It's more worrisome to have the caliber decreasing gradually over time.

Question 2

started having pencil thin stool. i'm really scared! do i have colon cancer?

Accepted Answer

It is concerning: You are correct in being concerned, particularly if this is a change. When the stool gets thinned like you are describing, you are concerned that there is something that is obstructing the normal pathway such as a cancer. You should have this worked up by your physician who may have you do tests like colonoscopy or ct scan.

Question 3

if a colon cancer is in advanced stage , it makes the stools thin every day? because i had thin stool 2 weeks ago, then normal and today again. help?

Accepted Answer

Cancer Paranoia: Colon Cancer does not make "thin' stools.  Where and why are you getting this obsessive paranoia thinking? You list Colon Cancer in your list of conditions. Are you pretending? Do we need to get you to the psychiatrist's office for a full evaluation of your mental state?  Do you really have a formal diagnosis of cancer?

Question 4

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.

Accepted Answer

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.

Question 5

i have soft thin stool. im so worried. is it colon cancer?i have hemorrhoids. no blood no wt loss and no pain in abd. i felt bulgng in rectum.

Accepted Answer

Colon cancer: At your age colon cancer is highly unlikely.  Hemorrhoids can cause your problem, and occur often with constipation.  Adjust your diet with more fruits, vegetables, carrots, lots of fluids.  To check on hemorrhoids you will need to see your doctor for a check up.

Question 6

been having thin/narrow stools.clear rectal exam by gp/no blood in stool.should i fear colon cancer?i'm 39 &had adenocarcinoma insitu of cervix 4yrago

Accepted Answer

Possible lesion: In situ adeno unrelated unless some for of radiation employed that could narrow distal bowel.  Narrowing of stool suggests that there is some constriction of bowel causing a narrowing of the lumen and thus the stool.  Blood does not have to be present but relying on a gp rectal not satisfactory.  Sigmoidoscopy at a minimum and colonoscopy more accepted for this problem.

Question 7

do narrow stools always indicate colon cancer?

Accepted Answer

No: More commonly due to spasm in lower colon.  However, sudden change in stool caliber, "pencil thin" stools, cramps, bleeding, nausea, weight loss need evaluation. Ongoing symptoms need evaluation. At the least, this should involve a doctor visit, perhaps other tests.

Question 8

23 .f no cancer history. since 2 days inconsistency in bm. i go once a day but find hard to release. lil narrow stools. got gas.no blood colon cancer?

Accepted Answer

Unlikely: A diagnosis of cancer of the intestines at 23 yr of age is very unusual. If you are constipated and there is  larger piece of stool blocking  passage of stool, this may cause thinner stools. Try to have more fiber in your diet and stay hydrated.

Question 9

i have been having lower back pain, and pain in my right side.. along with narrow stools quite frequently. could these be related? colon cancer?

Accepted Answer

Um: Colon cancer could be but not the first thing to consider. You could have urinary issues, stones, infection, irritable bowel. I would see your doctor for a full history and physical. Good luck

Question 10

would symptomatic colon cancer be missed on 3 separate ct scans? i am only 37 but have had narrow stools and small amounts of blood for past  year.

Accepted Answer

Unlikely : Best test would be a colonoscopy for your symptoms or at least a sigmoidoscopy. Usually if a colon cancer had symptoms a year ago those symptoms would have progressed over the ensuing 12 months and by now it would have been obvious by your symptoms and ct scan.
