Mohs surgery
（重定向自Chemosurgery）
Mohs surgery, also known as chemosurgery, developed in 1938 by a general surgeon, Frederic E. Mohs, is microscopically controlled surgery used to treat common types of skin cancer. During the surgery, after each removal of tissue and while the patient waits, the tissue is examined for cancer cells. That examination informs the decision for additional tissue removal. Mohs surgery is one of the many methods of obtaining complete margin control during removal of a skin cancer (CCPDMA –complete circumferential peripheral and deep margin assessment.) using frozen section histology. CCPDMA or Mohs surgery allows for the removal of a skin cancer with very narrow surgical margin and a high cure rate.
