Description

also called PIN. A condition in which there are changes in how the prostate gland cells look under the microscope. The changes are classified as low-grade, meaning that the cells look almost normal, or high-grade, meaning that they look more abnormal. The condition is not cancer, but it may lead to the development of cancer. High-grade PIN is more likely to become cancer than low-grade PIN. See also prostate, atypia.
