Blood Test Clues: Unveiling Colon Cancer's Hidden Signs
What Blood Test Results Indicate Colon Cancer?
Colon cancer is the third leading cause of cancer-related deaths in the United States. It's a treatable disease if it's caught early, but unfortunately, many people don't know they have it until it's in an advanced stage.
One way to detect colon cancer early is through blood tests. While no single blood test can definitively diagnose colon cancer, certain tests can indicate that further evaluation is necessary.
What Blood Test Results Indicate Colon Cancer?
Several blood tests may suggest the presence of colon cancer. These include:
- Carcinoembryonic antigen (CEA): CEA is a protein that is produced by some types of cancer cells, including colon cancer cells. High levels of CEA in the blood may indicate the presence of colon cancer, but it can also be elevated in other conditions, such as smoking and inflammatory bowel disease.
- Carbohydrate antigen 19-9 (CA 19-9): CA 19-9 is a protein that is produced by some types of cancer cells, including colon cancer cells. High levels of CA 19-9 in the blood may indicate the presence of colon cancer, but it can also be elevated in other conditions, such as pancreatitis and cirrhosis.
- Alpha-fetoprotein (AFP): AFP is a protein that is produced by the liver. High levels of AFP in the blood may indicate the presence of liver cancer, but it can also be elevated in other conditions, such as pregnancy and hepatitis.
- Human chorionic gonadotropin (hCG): hCG is a hormone that is produced by the placenta during pregnancy. High levels of hCG in the blood may indicate the presence of certain types of cancer, including colon cancer.
- Complete blood count (CBC): A CBC measures the number of red blood cells, white blood cells, and platelets in the blood. A low red blood cell count (anemia) may be a sign of colon cancer, as cancer can cause bleeding in the colon.
- Liver function tests: Liver function tests measure the levels of certain enzymes in the blood that are produced by the liver. Abnormal liver function tests may be a sign of liver cancer, which can be caused by colon cancer that has spread to the liver.
- Kidney function tests: Kidney function tests measure the levels of certain substances in the blood that are filtered by the kidneys. Abnormal kidney function tests may be a sign of kidney cancer, which can be caused by colon cancer that has spread to the kidneys.
- Electrolyte levels: Electrolyte levels measure the levels of certain minerals in the blood, such as sodium, potassium, and chloride. Abnormal electrolyte levels may be a sign of dehydration or other medical conditions, including cancer.
Benefits of Early Detection
Early detection of colon cancer is important because it leads to better outcomes. When colon cancer is found early, it is more likely to be curable. The five-year survival rate for colon cancer that is found early is over 90%.
If you are at risk for colon cancer, talk to your doctor about getting screened. Screening can help detect colon cancer early when it is most treatable.
