Description

CA-125 is a protein found in the blood that can be used as a tumor marker to help screen for and monitor certain cancers, particularly ovarian cancer.

Why the CA-125 Test Is Important

Ovarian Cancer:

  • Elevated CA-125 levels are often found in individuals with ovarian cancer.
  • The test can help detect early signs of ovarian cancer in high-risk individuals.
  • CA-125 levels are also useful for monitoring treatment effectiveness and checking for recurrence.

Other Cancers:

  • CA-125 levels can sometimes be elevated in other types of cancer.

Other Conditions:

  • Certain non-cancerous conditions can also raise CA-125 levels, including:
  • Inflammatory diseases
  • Recent surgery
  • Uterine fibroids
  • Menstrual cycle changes
  • Ectopic pregnancy
  • Liver cirrhosis
  • Diverticulitis
  • Endometriosis
  • Pelvic inflammatory disease
  • Peritonitis
