Lancing is a method used in medical procedures to make a small incision or puncture in the skin. This technique is often employed to drain fluid from a cyst or abscess, allowing for relief from pressure and pain. It can also be used to obtain a sample of tissue for further examination. In addition to its medical applications, lancing is commonly associated with the practice of lancing a finger to obtain a drop of blood for testing, such as in diabetes management. This quick procedure helps monitor blood sugar levels and is essential for effective treatment.
