Which procedure involves the use of chemicals to destroy diseased tissue?

The procedure that involves the use of chemicals to destroy diseased tissue is chemosurgery. This technique utilizes chemical substances to selectively eliminate abnormal or diseased cells, making it particularly effective in treating conditions such as skin cancer. The chemicals work by causing necrosis in the targeted tissue, thus helping to ensure that the diseased cells are effectively removed while sparing surrounding healthy tissue.

In contrast to chemosurgery, cryosurgery employs extreme cold to freeze and destroy unwanted tissue, and sutures are primarily used for closing wounds or surgical incisions, with no direct destructive action on tissue. Grafting refers to the process of transplanting tissue from one site to another, which does not involve chemical destruction of diseased tissue but rather aims to promote healing and repair. Thus, the correct answer is rooted in the specific mechanism of action of chemosurgery regarding the destruction of abnormal tissues.
