Overview

Adnexal tumors are growths of cells that form on the organs and connective tissues around the uterus. Adnexal tumors most often aren't cancerous, but they can be cancerous.

Adnexal tumors occur in the:

  • Ovaries
  • Fallopian tubes
  • Connective tissue around the ovaries or fallopian tubes

Diagnosis of adnexal tumors involves a careful physical exam, imaging tests and, sometimes, surgery. Treatment for adnexal tumors depends on the specific location and types of cells involved.
