My understanding there are two major concerns with this polyp (1) location-ascending colon, (2) was the polyp completely removed. If polyp was completely removed you are safe for now.
According to my research the problem is these polyps are hard to detect and remove completely. If not removed completely, they grow back fast, and may turn into cancer. According to my research this may happen before the next scheduled colonoscopy.
How can we be sure it is removed completely. Doesn't seem to be a definitive answer out there. Does anyone know? My gastro doctor said he removes the entire polyp in one piece, but there are serrated edges so I can see how cells can be left behind.
This is flipping me out to wait (3) years seems too long.
Diane E-
Welcome to the Forum, and I'm sorry to hear that you still have some unanswered questions after receiving your colonoscopy report.
I don't have the answers myself, but there are some resources available that may help you clarify the situation and get better answers from your doctors.
For now, what seem to missing are some of the critical details pertaining to aggressiveness and risk that should have been included in the pathology report of your polypectomy procedure.
In the U.S., the College of American Pathologists issues standards that are supposed to be followed by the pathologists whenever they are reporting on the outome of polypectomies. Some of the data fields are required while others are optional. Required fields, such as Histological Type and Grade of the pre-cancer, etc., can tell how aggressive and serious the pre-cancerous polyp might be.
What I would suggest is for you to download the 16-page document below and check which of the required data fields are actually given in your colonoscopy report.
Protocol for the Examination of Excisional Biopsy or Polypectomy SpecimensVersion 4.3.0.0, December 2023, 16 pages.
https://documents.cap.org/protocols/ColoRectal.Bx_4.3.0.0.REL_CAPCP.pdfI may have some additional comments later on, but for now the important issue is how the pathologist evaluated the specimens.

If the pathology report does confirm a pre-cancerous sessile serrated polyp, then please read the following article:
What happens if they find serrated polyps during my colonoscopy?Hyperplastic polyps are common and aren’t a cause for concern.
But if your provider suspects a precancerous type of serrated polyp, they’ll need to remove it. This is necessary both to confirm what type it is and to make sure it doesn’t progress to cancer.
If it does turn out to be precancerous,
your provider will want to schedule your next colonoscopy relatively soon, to make sure they don’t miss any new ones."

Yes, theoretically. the pathologist can include data iems in his report that can give this type of information. The main relevant data item is the one pertaining to "Resection Margin", which tells how many mm of tissue on the edge of the specimen are completely free of cancerous or pre-cancerous cells. But this type of assessment depends on how well the doctor cut the polyp out and whether he made sure that the cut in all directions and underneath the polyp was made far enough away from the visible polyp to allow some normal, non-polyp tissue to be included in the excised specimen. In other words, the specimen must be excised in such a way that the polyp is enclosed or surrounded by at least several millimiters of normal tissue in all directions. I'm not sure that there is any way to verify this from the pathologist's report. ***
The other important thing about the pathologist's report is whether the report actually gave any evidence that the polyp was in fact pre-cancerous. The key term that should be in the report is "dysplasia" since this is the histological attribute that identifies the polyp as being pre-cancerous. It is important to note that not all serrated polyps have "dysplasia'. Many serrated polyps have the attribute "hyperplasia', which means that they are
not precancerous.
Do you have a copy of the pathologist's report? Can you look through it to see what it says about the histological grade of the polyp? Note: I think that the doctor cannot make a definitive assessment visually during the colonoscopy procedure; I think it requires a pathologist's electron microscope to assess the histological detail.

Note: Here is an article that explains in great detail how to remove flat polyps correctly. The technology does exist for doing this, but it is not clear if gastroenterologists have the kind of colonoscopes that will allow all of the steps to be taken to excise the flat polyps with this type of precision.
