What type of resection scraps away the tumor during the procedure?

Curettage is a surgical procedure that involves scraping away tissue. This technique is often used in situations where a tumor or abnormal tissue needs to be removed by debriding the area, usually utilizing a curette, which is a sharp, spoon-shaped instrument designed for this purpose. Curettage allows for the removal of localized and superficial lesions, making it suitable for certain types of tumors, particularly in the skin, cervix, or other accessible areas.

In contrast, en bloc resection entails removing a tumor along with surrounding tissue, including any involved surrounding organs or structures, in a single large section. Excision resection focuses on removing a tumor with a margin of healthy tissue around it, while wide margin resection involves removing the tumor along with a broader margin of healthy surrounding tissue. While these methods can also achieve tumor removal, they do not primarily utilize a scraping technique as curettage does.
