Is CA125 raised in bowel cancer?

What cancers does CA125 detect?

Cancer antigen 125 (CA125) is a protein found on most ovarian cancer cells that is secreted into the blood stream and can be measured.

The CA125 blood levels can be increased in ovarian cancer and other cancers including:

  • uterine.
  • fallopian tube.
  • pancreatic.
  • breast.
  • colorectal.
  • lung.
  • stomach.

What cancers have elevated CA125?

Conditions that may cause an elevated CA-125 level in the blood include:

  • Ovarian cancer.
  • Cancers of the pancreas, breast, and lung.
  • Endometriosis.
  • Uterine fibroids.
  • Pregnancy.
  • Menstruation.
  • Liver disease.

Does bowel cancer show up in blood tests?

No blood test can tell you if you have colon cancer. But your doctor may test your blood for clues about your overall health, such as kidney and liver function tests. Your doctor may also test your blood for a chemical sometimes produced by colon cancers (carcinoembryonic antigen, or CEA).

Can you have a high CA125 and not have cancer?

If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.

How accurate is the CA125 blood test?

Results: Using a CA125 cutoff of 30 U/mL, an overall sensitivity of 94.8% (96.6% specificity) was obtained when comparing malignancies versus healthy postmenopausal controls, whereas a cutoff of 65 U/mL provided a sensitivity of 83.9% (99.6% specificity).

Can stress cause CA125 to rise?

The most popular current theories suggest that CA 125 is synthesized by mesothelial cells in response to stress, which can be either mechanical stress caused by fluid overload, or inflammatory stress instigated by the release of mediators such as TNFα and interleukins [5,6].

Why is my CA125 raised?

CA125 is produced by some ovarian cancer cells. A high level of CA125 in your blood could be a sign of ovarian cancer. But a raised CA125 level does not mean you definitely have cancer, as it can also be caused by other conditions such as endometriosis, fibroids and even pregnancy.

How much do fibroids elevate CA 125?

Over one-third (10/26) of the patients with uterine fibroids had increased (greater than 90th centile of the controls) levels of CA 125 before GnRH therapy or hysterectomy.
