How often do you need a colonoscopy if they find pre cancerous polyps?

How often do you need a colonoscopy if they find pre cancerous polyps?

It depends on: Several things including the type, size, and number of polyps. Your polyps were likely adenomas, not hyperplastic polyps, if you were told they were pre-cancerous. If you only had 1 or 2 small (<10 mm) adenomas, next colonoscopy in 5-10 years. But >2 adenomas, or >10 mm in size, almost all guidelines suggest repeat colonoscopy in 3 years. Serrated polyposis syndrome is annual exam. Hope helpful ...Read more

Precancerous (Definition)

A precancerous condition (or premalignant condition) is a generalized state associated with a significantly increased risk of cancer. If left untreated, these conditions may lead to cancer. Premalignant lesion is a morphologically altered tissue in which cancer is more likely to occur than ...Read more

I had a colonoscopy and 1 polyp was found. It was biopsied and found to be precancerous. What characteristics of a polyp make it pre.? What r prebiotics

Microscopy: The pathologist who read out your polyp under the microscope spends several years learning to tell the ones that are premalignant and this would take more than 400 words. Prebiotics remain unproven as a means of reducing colon cancer risk; claims have been around for a decade without anything strong, ask your gastroenterologist about aspirin. ...Read more

I had an endo & colonoscopy. The nurse called last wk & adv that the results showed the polyp removed was precancerous but benign;what does this mean?

Adenomatous polyp: You most likely had an adenomatous polyp. These polyps are the most common type of polyp we find in the colon, occurring in roughly 20-30% of patients. Over a long time (10 years), these polyps can possibly turn into cancer, so we call them "pre-cancerous". However we also often call them "benign" as they are 1) very common 2) we remove them, and 3) technically they are not cancer yet. ...Read more

Yeah I got a colonoscopy about 3 weeks ago and I still have severe diarrhea is that normal or should I be concerned they cut a pre-cancerous polyp out?

Yeah I got a colonoscopy about 3 weeks ago and I still have severe diarrhea is that normal or should I be concerned they cut a pre-cancerous polyp out?

No concern: Medication taken to clean bowel could lead to diarrhea but having removed or not removed polyp, unless latter was malignant is unassociated with bowel malignancy. Unless congenital polyposis with APC gene mutations present, polyps only associated with 5% of bowel carcinomas. Latter derived from field effect, transformation possibly related to infection from organisms like polyoma virus ...Read more

Mother had precancerous colon polyp at 40, father had noncancerous polyp at 40... when should I have first colonoscopy?

Mother had precancerous colon polyp at 40, father had noncancerous polyp at 40... when should I have first colonoscopy?

It depends on....: You may be at a higher risk for polyps than the average person where colonoscopy is advised at 50 years of age. For high risk it is advised at 40 years. But if you have any symptoms of blood loss or abdominal symptoms anytime, you should get your colon checked before you turn 40. If you want to be free of any anxiety, then do it sooner (now or during this year provided you can handle the expenses. ...Read more

I just had a precancerous polyp removed from a colonoscopy that doc said he does not see at my age39.The pain led me to find ovarian cyst is it cancer?

Unlikely: Ovarian cysts are very common. 3 cm or less is considered a normal functional follicular cyst related to normal ovulation cycles. A cyst greater than 5 cm in a premenopausal patient should be followed and managed by an OB GYN doctor. A pelvic ultrasound will show if the cyst is simple (no solid parts) or complex (internal solid components). Vast majority of ovarian cysts are benign. ...Read more

If you had polyps last time you had a colonoscopy does than mean it's expected to continue the same.

There are higher odd: Some people are more prone to form polyps. So if you have had the polyps removed before, you are considered higher risk for more polyps and advised to undergo colonoscopy in 5 years, as opposed to 10 years for someone who did not have any polyps in their first colonoscopy. ...Read more

I had a colonoscopy and they removed 5 polyps. What is the average amount that is removed and is 5 a lot?

5 is a lot: 5 polyps found at colonoscopy is a lot but not uncommon. Most important is the type of polyp. Hyperplastic polyps are not malignant and are not the concern that we associate with adenomatous polyps which can be premalignant. Most worrisome are adenomatous polyps with atypia which should be aggressively removed. Many invasive cancers start as a benign polyp and can be prevented by polypectomy! ...Read more

If when taking a colonoscopy and they see polyps do they remove them and when they remove them and something is found what medicine do they use?

If when taking a colonoscopy and they see polyps do they remove them and when they remove them and something is found what medicine do they use?

Yes: Polyps are removed with instruments passed through a channel in the scope. Instruments are used to cut the polyp and extract it. Very rarely (if polyp large and/or flat) there is a need to inject the polyp prior to removing it, and the most common injected medicine would be epinephrine and normal saline. ...Read more

I had a clean colonoscopy at age 45. No polyps etc. Just turned 50 and wondering if I should do it now, or is it ok to wait. Thanks in advance, ?

Maybe: First question is do you have any symptoms to suggest colon disease. Change in bowel habits, rectal bleeding, unexplained weight loss most commonly. If not, next question is family history. Any one in your first degree family have colon cancer or polyps? If yes then have one at 5 years, if no then recommendations are to wait 10 years, again, if no symptoms. ...Read more

Had a colonoscopy yesterday, removed four polyps, one of which had to be clip, how long dose the clip stay in? Also not feeling 100% lot of rectal press.

Clip will pass: The clip on the stalk of a polyp will fall off after a few weeks. It will likely pass without you knowing about it. The rectal pressure after colonoscopy is due to irritation of the rectal canal from manipulating the colonoscope during the procedure. It should resolve within a day or two after the procedure. ...Read more

I am 31 I had my first colonoscopy in february of this year, is there any chance that tumors or polyps can appear soon after? It was negative!

Depends...: Depends on--genetics (is there an underlying polyposis syndrome); the skill of your colonoscopist & the quality of your colon preparation; risk reduction (eat more fiber, less fat, watch your weight); predisposing factors (crohn's colitis, ulcerative colitis), age (incidence of polyps increases with age), more. That being said, a negative exam at age 31 offers opportunity for polyp prevention. ...Read more

I was told to not fly for two weeks after removing a polyp during a colonoscopy. Is this really necessary? I have a business trip planned in 4 days.

Probably not: If your colonoscopy was without incident, uneventful, and if your recovery has been that way also, I believe you should be able to go to your business trip. However, please let your doctor know about this and take his advice also. ...Read more

Which tests are considered "routine" when trying to diagnose rectal and anal problems? I have had a colonoscopy, I had a few polyps and inter. Hemmorh

Which tests are considered "routine" when trying to diagnose rectal and anal problems? I have had a colonoscopy, I had a few polyps and inter. Hemmorh

Colonoscopy is it!: For common rectal or anal problems such as rectal bleeding or pain, a full colonoscopy is commonly "routine" at age 53. Depending upon the symptoms, a simple anoscopy or rigid or flexible sigmoidoscopy might be recommended. Importantly' rectal bleeding should never be attributed to hemorrhoids without an endoscopic exam to document hemorrhoids or, more importantly, rule out a malignancy. ...Read more

Colonoscopy showed no polyps but an erythematous area was found and it was biopsied. What could that mean?

IBS has no findings: Typically, inflammation anywhere is associated with erythema. While it is more diagnostic of acute or chronic inflammation in the stomach or esophagus, erythema in the colon could mean nonspecific inflammation. The biopsy will determine if this is something more serious such as Crohn's disease. IBS has no abnormalities on colonoscopy. ...Read more

Regarding a colonoscopy, I understand there is a ranking # that is used to track dr's. Procedure outcome on finding polyps?

Adenoma detection: Adenoma detection rate is the standard you are thinking of (different from polyp detection rate as not all polyps are adenomatous, or precancerous). The minimum standard is around 25 percent for average risk screening colonoscopies, though many groups, like ours, achieve rates closer to 40%. These rates are usually self reported and take a bit of work to compile, so not everyone reports them. ...Read more

I had a colonoscopy that revealed over 1, 000 polyps. Is there any way this doesn't require collectomy?

Unusual to count: This high... if you indeed have a genetic syndrome (FAP or similar) yes a colectomy needs to be considered. A lot of it also depends on the pathology of the polyps themselves. You need to discuss this with your GI doc, surgeon and possibly a genetic counselor. ...Read more

Adenomatous polyp with atypia means.? Just got report from colonoscopy report. No need to worry? Let me knw sir

There are some: Missing pieces of information that may be helpful. Size and location of polyp? Tubular or villous (a specific type of growth pattern the pathologist notes). Atypia designates that there may have been some dysplasia, a pre-cancerous type of change. As long as the polyp has been completely removed, no need to worry now. Colonoscopy should be repeated in future based on factors above. Good wishes:) ...Read more

Relax: Great majority of polyps are not cancer. Usually takes several years to develop cancer. Polyps>1 cm in size are most noteworthy. Most important colonoscopy is your first- to find polyps that developed over the decades. Should get follow up exams. Frequency depends on polyp number, size, type, family history. Discuss w/ md. Colonoscopy made headway in fight against cancer. Talk about diet, activity. ...Read more
