Complete circumferential peripheral and deep margin assessment

CCPDMA is superior to standard bread loafing due to very low false negative error rate.

[citation needed] The first advantage of CCPDMA method is that it allows for the complete examination of the entire surgical margin of the specimen.

As the CCPDMA surgery is frequently performed using frozen section pathology, immediate reporting of positive surgical margin is made, and the tumor can be completely removed in the same day.

Traditional pathology processing is called "bread loafing", and only allows for the partial examination of the surgical margin.

Serial sectioning allows CCPDMA approaches near-complete evaluation of the surgical margin and may be performed by pathologists, dermatologists, and surgeons.
