A resection margin or surgical margin is the margin of apparently non-tumorous tissue around a tumor that has been surgically removed, called "resected", in surgical oncology. The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue.
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.
Excisional biopsy involves surgically removing the suspicious area of the breast to examine it under the microscope for diagnosis. One method is wire-guided (or wire-localized) excisional biopsy, where a wire is inserted into the breast and repeatedly imaged using breast ultrasound or mammography until the technician sees that the tip is ...

A re-excision lumpectomy is performed if the margin is detected to be positive or cancerous cells are very close to the margin. [9] Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) may be used to determine if the cancer has progressed away from the breast and into other parts of the body. [10]
Pictogram of margin controlled histology or CCPDMA Pictogram of standard bread loafing histology False negative in standard bread loafing histology. Bread loafing is a common method of processing surgical specimens for histopathology. The process involves cutting the specimen into 3 or more sections. [1]
When cancer is suspected, a variety of biopsy techniques can be applied. An excisional biopsy is an attempt to remove an entire lesion. When the specimen is evaluated, in addition to diagnosis, the amount of uninvolved tissue around the lesion, the surgical margin of the specimen is examined to see if the disease has spread beyond the area ...
Surgical pathology is the most significant and time-consuming area of practice for most anatomical pathologists. Surgical pathology involves gross and microscopic examination of surgical specimens, as well as biopsies submitted by surgeons and non- surgeons such as general internists , medical subspecialists, dermatologists , and interventional ...
