Do narrow stools always indicate colon cancer?

Do narrow stools always indicate colon cancer?

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.

Cancer (Definition)

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

Can holding your stool in cause colon cancer when you are 50?

Can holding your stool in cause colon cancer when you are 50?

No!: But it's not a good idea! when your body sends you the signal that is time to move her bowels, you should listen. It's really pretty smart. Obviously, one cannot always get to a bathroom when we get that signal. But if you do, go move your bowels. Your colon, rectum, and especially the hemorrhoidal veins will thank you (prevent hemorrhoids!) good luck!

If colon cancer stars causing narrowed stools, is it possible that stools with normal diameter to appear, or they will always stay the same or smaller?

If colon cancer stars causing narrowed stools, is it possible that stools with normal diameter to appear, or they will always stay the same or smaller?

Usually stay narrow: You have a caliber restricting growth "napkin Ring Lesion" that doesn't get better on it's own. Usually gets worse till it fully obstructs.

If 'pencil' stool and 'narrow' stool are signs of colon cancer but exactly how thin of the stool consider as pencil stool or narrow ?

Any change.: Any change in stool caliber warrants investigation. If one's stool has changed in size (narrow), to any degree, a colonoscopy is warranted. This could be an early sign of colon caner.

Does colon cancer usually cause bright red blood in your stool or is the blood darker in color?

Does colon cancer usually cause bright red blood in your stool or is the blood darker in color?

Usually occult...: It is usually not "red"-ily visible until late in the disease. Then it can be dark or bright, depending on rate of loss and location of leakage, as tends to darken with more time in GI tract. Also may be associated with narrowed caliber of stool. If concerned, see dr for fecal blood testing & if positive, referral for colonoscopy.

Family history?: Hard stool may cause streaking with blood. Take fiber laxative and drink plenty of water to avoid hard stools. Unless a close relative of yours had colon cancer before the age of 50, I would not be too concerned about colon cancer. When you turn 50 that would be time to get a colonoscopy.

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?

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.

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?

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

Is 1/2 a penny size of mucus in stools 3x/wk and loose stools 1x/week a cause for concern? Could it be colon cancer? No family history.

Is 1/2 a penny size of mucus in stools 3x/wk and loose stools 1x/week a cause for concern? Could it be colon cancer? No family history.

Here are some...: Seeing various amount of mucus coated on stool is common and not clinically significant as long as having no blood, moving bowel regularly, and living a healthy active vibrant life. More? Ask Doc timely. If still in doubt, follow instructions in http://formefirst.com/eNewsletter06.html.

Chance that 4 CT scans over 2 1/2 years would all miss sympotomatic colon cancer (narrow stool, occasion blood), also sigmoidscope to 35 cm.

Fairly high risk: CT scans are NOT good tools for looking inside the bowel. Endoscopy is the preferred tool, but a sigmoidoscopy, at its best, misses looking at half the colon. A look to merely 35 cm has missed about 85-90% of the colon. The usual method to evaluate the colon is a complete colonoscopy.

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.

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.

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.

Do colon cancer polyps cause constant blood in the stool or intermittently? Do polyps only bleed when they're ruptured from straining passing stool?

Do colon cancer polyps cause constant blood in the stool or intermittently? Do polyps only bleed when they're ruptured from straining passing stool?

Intermittent: Bleeding form polyps is intermittent and depends on the size and type of polyp. That is why yearly testing is recommended. You may consult this site for information about blood in stool. http://www.webmd.com/digestive-disorders/blood-in-stool#1 For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

Can colonoscopy(done by an incompetent doctor) cause colon cancer? Suppose the doctor nicks something you know? There's bright red blood in my stool.

Colonoscopy: Colonoscopy by an incompetent doctor cannot cause colon cancer although it could have missed colon cancer. If a hole was put in the colon then there could be severe infection. Recommend reviewing your results of the colonoscopy because polyps, hemorrhoids, colitis, and diverticulosis could all cause rectal bleeding.

28 yrs old, male. Do narrow stools always indicate colon cancer or are there other reasons? No blood in stool.  Bloating and gas.

No – but what's up?: And narrowed caliber of stool can be commonly associated with colon carcinoma in any age group. It relates to the relative constriction of the rectum prior to evacuation. Other conditions include rectal stenosis, a sizable rectal polyp, or other conditions serving to narrow and constricted the normal sized stool. Best let a gastroenterologist evaluate you by colonoscopy and anoscopy.

Hematochexia: Negative sigmoidoscopy and CT sacn of pelvis and Abdomen. May need a full colonoscopy doubt colon cancer for 3 years without significant progression. Other cause like IBD more likely
