What does incision mean?

An incision is a cut made into the body during surgery.

Traditionally, incisions are made with surgical instruments like scalpels. However, they can also be made with lasers or robotic tools. Sometimes, incision refers to the scar resulting from such a cut.

Incision is the noun form of the verb incise, meaning to cut into. The noun form incision is more commonly used.

More generally, incision can refer to any cut or gash, but it is primarily used to refer to surgical incisions.

Example: The surgeon explained that she would need to make three small incisions in my abdomen in order to remove my appendix.

Where does incision come from?

The first records of the word incision come from the 1300s. Incision is the noun form of incise, which derives from the Latin verb incīdere, meaning “to carve” or “to cut into.”

Steady-handed surgeons make incisions with scalpels, lasers, or robotic tools. Some incisions are made for the purpose of exploratory surgery, which typically involves trying to diagnose what may be wrong with a certain body part. In most cases, though, incisions are made so that a body part can be repaired or removed. Sometimes, incisions are very small, such as in a laparoscopic appendectomy (a procedure to remove the appendix that uses a tool called a laparoscope). Other procedures require incisions that are quite big, such as in a cesarean section. Hopefully you won’t need any, but if you do, may all your incisions be done with precision!
