Screening (Definition)

Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more

50+ and smoke around 2-3 fags a day. Do i need a colonoscopy screening even if i don't have symptoms?

50+ and smoke around 2-3 fags a day. Do i need a colonoscopy screening even if i don't have symptoms?

Yes: Regardless of your smoking history, you should have got your first screening colo as soon as you turned 50. Observational trials suggest that smoking increases the risk of polyps and colon cancer to some degree, (not to mention multiple other cancers and cardiopulmonary issues) so if you want my advise, get rid of those cigarettes for good. ...Read more

Are there less invasive and less expensive options for preventative screening colonoscopies?

Are there less invasive and less expensive options for preventative screening colonoscopies?

Yes: Double contrast barium enema xray or ct colonography however if some thing is found on either of the above, you will still need a colonoscopy. If either are negative, there is no guarantee that something wasn't missed due to the prep or performance of those studies. Colonoscopy is the gold standard. ...Read more

What percentage of colonoscopy screenings end up damaging or perforating the colon? 1/1000? 1/2000?

What percentage of colonoscopy screenings end up damaging or perforating the colon? 1/1000? 1/2000?

Very low: For screening colonoscopies the rate of serious complications is generally less than 0.1%. The rate is higher if polyps are removed and the rate also goes up with age of the patient. The rate is lower for doctors who do a lot of them, ie, gastroenterologists. ...Read more

Mom is smoker ( around 2 fags a day). 52 yrs. Is a colonoscopy screening required for all smokers above 50 even without symptoms?

Mom is smoker ( around 2 fags a day). 52 yrs. Is a colonoscopy screening required for all smokers above 50 even without symptoms?

Not the smoking: It's the age. All people, non-smokers and smokers, should have colonoscopy initially at age 50 and then every 5 years. Pre-cancerous polyps don't have symptoms. I assume fags=cigarettes ...Read more

Can you give a list of all cancer screening tests for people who have no present symtoms of cancer, for example, a screening colonoscopy; how often?

Can you give a list of all cancer screening tests for people who have no present symtoms of cancer, for example, a screening colonoscopy; how often?

Only a few exist: Problem: cancer SLOW but usually, except for skin, DETECTED LATE. Thus bigger issue: realize that catching/stopping cancer is a key immune system function (controlled from brain), avoid foods which drive cancer (sugars), stay thin & keep up on science. Proven for men: check skin, mouth, thyroid & lymph nodes for growths, CBC, Electrophoresis, T. Markers, PSA (<1.0 ng/dL) & endoscopy>remove polyps. ...Read more

Might it be that a colonoscopy prevents colon cancer, or is it simply a screening tool?

Might it be that a colonoscopy prevents colon cancer, or is it simply a screening tool?

Yes it can: Colonoscopy is done to look for polyp which are precursors of cancer. So if the polyp is removed before it becomes cancerous, then we have prevented development of colon cancer. ...Read more

I am considering a screening sigmoidoscopy over that of a colonoscopy due to more preparation and procedural involvement. No family history. Wise?

Colonoscopy : I would suggest a colonoscopy if you are able, as it is a more complete screening. If normal you will not need another for 10 years. The sigmoidoscopy only looks at the lower portion of your colon. ...Read more

Is a nurse anesthetist, to assist GI during a screening colonoscopy, a good choice over an anesthesiologist?

Anesthesiologist: A nurse anesthetist (crna) is a cheaper, less trained alternative to an anesthesiologist. The md is likely the better option. There are always bad mds and there are some phenomenal crnas but your safest bet would typically be the more extensively trained md. That being said, most anesthetics are safe, and you will likely be fine, but colonoscopies have ended in deaths like any other procedure. ...Read more

Can i still have a screening colonoscopy (am due now) when i enter the md's office with white coat syndrome?

Sure...: But you won't get a colonoscopy without getting prepped (cleaned out) first. You get sedation before and during the procedure. Your vital signs will be monitored throughout. Your blood pressure should be well controlled in that environment. If your BP is dangerously high, e.g. 200/110, no screening for you that day the BP would be the bigger and more pressing issue. ...Read more

Mom is 52. Smokes 2-3 cigs a day. Does she need to get screening colonoscopy even without symptoms? What are chances of colorectal cancer?

Mom is 52. Smokes 2-3 cigs a day. Does she need to get screening colonoscopy even without symptoms? What are chances of colorectal cancer?

Needs colonoscopy : Studies have shown that all normal-risk individuals should have a screening colonoscopy starting at age 50 and repeated at least every 10 years if no polyps are found. All polyps should be removed. If there is a positive family history for colon cancer, screening should start at an earlier age. There is about a 5% lifetime risk of developing colon cancer. ...Read more

If 61 yr m had a -ve whole body pet+ct done for renal mets  1 yr ago, how long we can postpone colonoscopy (first time)screening for colon cancer?

Let me be: Sure i understand. She had a renal cancer removed, and that was more than a year ago, and pet showed no metastasis. She is asymptomatic and feeling well? There are advisories that colonoscopy should be done once each decade after 50. She would seem eligible for that, but there is no rush. ...Read more

Do colonoscopies screen for colon cancer?

Yes.: That is one of the main reasons for colonoscopy. The gastroenterologist usually can see every part of the colon wall and biopsy suspicious lesions. Often this is curative if found early. While not completely true, consider all polyps to be future cancers and most cancers come from polyps. Screening should begin at age 50 unless there is a history to suggest beginning earlier. ...Read more

How common is it to find ulcers during a colonoscopy?

The nature of ulcer: Ulcers of colonic mucosa could be seen in inflammatory bowel disease (ulcerative colitis or crohn's disease), ischemic colitis or psuedomembranous colitis. Ulcers of intestinal mucosa might be seen in colonic cancer. Biopsy in time of colonoscopy might be helpful to understand the nature of ulcer. Thank you for question. ...Read more
