Can a doctor tell if polyp is cancerous right then and there once it removed?

It is not possible for a doctor to determine if a polyp is cancerous immediately after its removal. The process of determining whether a polyp is cancerous requires a more detailed analysis of the tissue sample. This analysis typically involves sending the polyp to a laboratory for microscopic examination by a pathologist. The pathologist will examine the polyp's cells and structures to determine if there are any abnormalities or signs of cancer. This process can take several days to complete, and the results will be communicated to the doctor who performed the polyp removal.
