Associated Errors and Recurrence Rate
This determination is made with the full understanding of "false negative error" intrinsic in the bread loafing technique of histology (also known as POMA - a term used by the NCCN). The higher is the false negative error, the higher is the recurrence rate of a cancer or tumor at the surgical margin. This is due to the misreading of a pathology specimen as being clear of residual tumor, when there is actually residual tumor left where the specimen was not cut and mounted on the histology slide. The "false negative error" is very low in the CCPDMA method of histology processing, and can be very high in the bread loafing (POMA) method of histology processing. In the bread loafing method of processing, one will note a high false negative error rate with narrow surgical margin; and one will note a low false negative error with a wide surgical margin Surgical margin has a much less significant effect on the false negative error rate of CCPDMA methods, allowing the surgeon to routinely use very narrow surgical margins (1 to 2 mm for non-melanoma skin cancer).

Famous quotes containing the words errors, recurrence and/or rate:
“Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?”
—Ernest Renan (1823–1892)
“Forgetfulness is necessary to remembrance. Ideas are retained by renovation of that impression which time is always wearing away, and which new images are striving to obliterate. If useless thoughts could be expelled from the mind, all the valuable parts of our knowledge would more frequently recur, and every recurrence would reinstate them in their former place.”
—Samuel Johnson (1709–1784)
“You are more than entitled not to know what the word ‘performative’ means. It is a new word and an ugly word, and perhaps it does not mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.”
—J.L. (John Langshaw)
