Ovarian cancer is a serious condition that affects thousands of women each year. Early diagnosis is crucial in improving the chances of successful treatment and recovery, and that’s why CA-125 and CEA levels are important indicators of the disease. This article will provide a comprehensive understanding of what CA-125 to CEA ratio for ovarian cancer is and why it is important.
What is CA-125 and CEA?
CA-125, also known as Cancer Antigen 125, is a protein found in the blood that is commonly used to monitor the progression of ovarian cancer. It is produced by the cells of the ovaries and other tissues in the body. The CA-125 test measures the level of CA-125 in the blood, which can be an indicator of the presence of ovarian cancer.
CEA, or Carcinoembryonic Antigen, is a protein that is produced by cells in the digestive system and other tissues. The CEA test measures the level of CEA in the blood, which can be an indicator of certain types of cancer, including ovarian cancer.
What is CA-125 level for Ovarian Cancer?
The normal range of CA-125 levels in women is 0 to 35 units per milliliter (U/mL). However, in women with ovarian cancer, the CA-125 levels can be much higher. The level of CA-125 can fluctuate for various reasons, such as menstrual cycles, pregnancy, and benign conditions like endometriosis. Fluctuations in CA-125 levels can make it difficult to interpret test results, which is why it is essential to consider other factors such as a patient’s symptoms and medical history.
What level of CEA indicates Ovarian Cancer?
The normal range of CEA levels in the blood is typically less than 5 ng/mL. However, in women with ovarian cancer, the CEA levels can be elevated. The CEA test is not used as often as the CA-125 test for ovarian cancer, but it can provide additional information to help diagnose the disease.
CA-125 to CEA Ratio for Ovarian Cancer
The CA-125 to CEA ratio is the ratio of the levels of CA-125 and CEA in the blood. This ratio is an important indicator of the presence and progression of ovarian cancer. A high CA-125 to CEA ratio can indicate the presence of ovarian cancer, while a low ratio can suggest that the disease is in its early stages.
CA-125 Blood Test for Ovarian Cyst
A CA-125 blood test can be used to diagnose an ovarian cyst, which is a fluid-filled sac that develops in or on the ovary. A high level of CA-125 in the blood can indicate the presence of an ovarian cyst, but it is important to consider other factors such as the patient’s symptoms and medical history before making a diagnosis.
CA-125 Greater than 1000
If the CA-125 levels in the blood are greater than 1000 U/mL, it can indicate the presence of ovarian cancer.
