CA 27-29 refers to a tumor marker blood test used to monitor people with breast cancer. It's a blood test that measures the amount of a protein, CA 27-29, in your blood. This test is not used for screening for breast cancer, but rather to monitor how well someone is responding to treatment or to detect if cancer has recurred or spread. CA 27-29 is a protein that can be released by both healthy and cancerous cells. However, higher levels are often seen in people with breast cancer, particularly those with metastatic (spread) disease.
How it's used:
The test is primarily used to monitor the treatment of breast cancer and to check for recurrence or spread.
Normal range:
The normal range for CA 27-29 is typically 0-38 U/mL.
Interpretation:
Higher levels of CA 27-29 may indicate that the cancer is growing or has spread, while lower levels may indicate that the treatment is working.
Limitations:
CA 27-29 is not a definitive test for diagnosing breast cancer, and elevated levels can also be caused by other conditions, such as benign breast conditions, ovarian cysts, and other cancers.
Other tumor markers:
Other tumor markers, such as CA 15-3, may also be used to monitor breast cancer.
Importance of doctor's consultation:
It's important to consult with a doctor to determine the appropriate testing and interpretation of results.

Janet, great info. Thank you!

It'a mainly to monitor stage 4 progression. Some doctors use it for earlier stages but there are other issues that will raise levels. 🥰

Thank you!!
