Hysteroscopy is used to examine the inside of the uterus. The hysteroscope is a thin instrument with a lens and a light source and a camera attached to one end. This allows very careful and thorough examination of the uterine cavity.

Hysteroscopy can help discover causes of bleeding, such as polyps or fibroids. It can be used to perform a biopsy of the uterus to check for cancerous growth, especially in postmenopausal women.
