A small scalpel is utilized to cut around the visible tumor. Unlike a normal surgical excision, a Mohs surgery cut is performed at a beveling between 10 and 45 degrees to allow visibility of all skin layers during pathological diagnosis. [8] A very small surgical margin is utilized, usually with 1 to 1.5 mm of "free margin" or uninvolved skin.
Complete circumferential peripheral and deep margin assessment (CCPDMA) is the preferred method for the removal of certain cancers, especially skin cancers. [1] [2]There are two forms of CCPDMA surgery: Mohs surgery and surgical excision coupled with margin assessment.
These are retained after the surgery and examined microscopically by a pathologist to see if the margin is indeed free from tumor cells (called "negative"). If cancerous cells are found at the edges (called "positive") the operation is much less likely to achieve the desired results.

A wide local excision of the breast aims to remove benign and malignant lesions while conserving the normal shape of the breast as much as possible. It is a form of breast-conserving surgery. A WLE can only be used for lesions up to 4 cm in diameter, as removal of any larger lesions could leave a visibly dented area in the breast.
The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) and early stage cervical cancer discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ). It is considered a type of conization. [1]
