Are all polylps found necessarily cancerous when you get a colonoscope?

Are all polylps found necessarily cancerous when you get a colonoscope?

No: Many polyps that present during this test are not cancerous, but if left in the colon, can develop into cancer. Tubular and villous adenomas can develop into cancer. Patients with familial polyposis syndromes can have many polyps throughout their colon, which makes malignancy almost certain. Sometimes the entire colon is removed to prevent it. ...Read more

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

When polyps are found during colonoscopy that are 2-3 CM in size why would a doctor leave them instead of taking a biopsy?

When polyps are found during colonoscopy that are 2-3 CM in size why would a doctor leave them instead of taking a biopsy?

Colonoscopy: Biopsies are usually only taken of any polyps that dont look normal. Polyps of that tiny size are unlikely to be a problem and to a trained eye, the risk of taking the biopsy probably higher than the risk of possible malignancy! I am sure you were told to have a follow up colonoscopy in 6 mos to 1 year. ...Read more

Oncology-  are nosebleeds a symptom of leukemia in kids?    I have read they are common , but also that they can mean cancer.  Normal vs worry some?

Mine have them: All 3 of my children have had nosebleeds from time to time and none have had cancer. Nosebleeds are almost always due to dry noses, nose-picking, dry air, colds, and or can just happen. Cancer is a very rare cause. Any doubts of course, please dont hesitate to bring them in to your pediatrician. There are no bad questions for your pediatrician! ...Read more

Do all colon cancers start as a polyp than can be found and removed on colonoscopy, or do some not have a "polyp stage"?

Not all colon cancer: Approximately 85% of colon cancers do start as polyps. The other 15 percent occur in cases of chronic inflammation. Cancer can develop in patients with ulcerative colitis with no polyp stage. The chronic inflammation itself can be a precancerous state. ...Read more

Leiomyomas: Uterine fibroids are growths of the smooth muscle wall of the uterus that can at times reach enormous sized producing symptoms secondary to bleeding or bulk size. At times they undergo malignant degeneration and result in a lesion, the leiomyosarcoma. One can embolize the blood supply to the bulky lesion or perform hysterectomy ...Read more

Why isn't HPV included in a routine STD test or pap? So many people have it and think they are STD free because they are ignorant about it.

Why isn't HPV included in a routine STD test or pap? So many people have it and think they are STD free because they are ignorant about it.

It usually is: It is the recommendation that it is done routinely but it is an expensive test with the technology not available everywhere. Accommodations must be made for docs not able to comply. You must remember, there are still people doing smears on a slide. For those docs that can get it done but don't, we must take the time to update our education if we are going to provide the service. ...Read more

Are rectal hemorrhoids dangerous and how do they differ from a polyp? I have just had a colonoscopy and have hemorrhoids - not malignant thankfully.

Are rectal hemorrhoids dangerous and how do they differ from a polyp?  I have just had a colonoscopy and have hemorrhoids - not malignant thankfully.

First of all: Hemorrhoids are NEVER "Malignant" and they are not "pleasant" to have but they are not DANGEROUS! Good bowel hygiene and proper diet will help and your Primary Care Provider can outline these suggestions to you! Worse case scenario is hemorrhoid surgery but this is usually NOT necessary!! Hope this helps!!! Good Luck! Dr Z ...Read more

What are odds cancer was missed when had scope, would they have seen thyroid, lymph nodes ect.  and if cancer not the reason for scope would they noti?

Anxious?: I don't think anyone can give you odds. We don't know the providers, the labs, what you told them, etc., etc. But - you sound very anxious and that is not good for you. Consider a psych eval and some therapy to guide you in how to manage your medical anxiety most effectively. There is a balance between ignoring your symptoms and being captive to them. I really can help. For now, talk to provider. ...Read more

I have a 4mm sessile colonic polyp. It wasn't removed but the penuculated ones were, they were also colonic ones at 7mm. Why? Is this strange? Thanks.

NMS: This is not my specialty but i would venture to guess that a sessile polyp is more risky to remove and the size is not too alarming. Did your GI ask you to return for a follow-up procedure? I think this is the question you need to ask the doctor about. ...Read more

Can entering  things in anal ( finger, pens,dildo,carrot,colonoscope,..) consider a risk factor for anal or rectal cancer(not with hpv and stds)

?

No: The link to HPV is clear-cut, but this won't up risk. Be careful with pens or anything else that can perforate your mucosa or that could become lodged there. If this is something you really want to do, with yourself or with others, fine. There's no understanding personal turn-ons. If this is compulsive / unwanted behavior, a short course of cognitive-behavioral therapy might free you from it. ...Read more

How is a colonoscope test done ?

Sedation: Colonoscopy is performed by placing a long, flexible tube along the entire colon and rectum via the anus. While people dread this, it is painless when done under sedation. The worst part is the day before when the "prep" is taken to purge the system. Although unpleasant, this will find polyps before they turn into cancers, thus saving one from major surgery. If you're 50, "get 'er done". ...Read more

Have researchers found that you could get cancer by wearing a bra?

Bra myths: My understanding is that a book written by anthropologists “dressed to kill” indicated that use of underwire bras could restrict lymphatic drainage & lead to accumulation of toxins in the breast. Based on this assumption, it was theorized that this could contribute to development of breast cancer. However, lymphatic drainage from the breast is not downward due to gravity – it moves >>. ...Read more

How can cancer get into a body?

How can  cancer get into a body?

It is the body: Cancer is a disease due to the failure of immunosurveillance. To put it simplistically, the body is like a huge assembly line and the quality control fails to reject the defective cells that are manufactured. There are several reasons as to why the defective cells are produced and research is still continuing on the causation. Cancer can be grown in lab animals but is not done so in humans. ...Read more
