Cancer Marker Screening


Cancer Marker Screening

Cancer marker screening involves the measurement of specific substances or biomarkers in the blood or other body fluids to detect the presence of cancer or monitor its progression. These markers are often produced by cancer cells or by the body in response to the presence of cancer. It’s important to note that the presence of a cancer marker does not necessarily confirm the presence of cancer, and further diagnostic tests are typically needed for a definitive diagnosis.

Here are some common cancer markers and the types of cancer they are associated with:

Prostate-Specific Antigen (PSA):

Associated with prostate cancer.

Used for screening and monitoring prostate cancer, but elevated levels can also be caused by other conditions.

CA 125:

Associated with ovarian cancer.

Elevated levels may be found in ovarian cancer and other conditions such as endometriosis.

CA 15-3 :

Associated with breast cancer.

Used to monitor breast cancer patients during and after treatment.

CEA (Carcinoembryonic Antigen):

Associated with colorectal cancer.

Also elevated in some other cancers, such as lung, breast, and pancreatic cancer.

AFP (Alpha-Fetoprotein):

Associated with liver cancer.

Also used in the diagnosis and monitoring of certain germ cell tumors and other conditions.

CA 19-9:

Associated with pancreatic cancer and certain gastrointestinal cancers.

Elevated levels may also be seen in other conditions

Sample Requirement

Blood Sample Type:

Venous Blood: A venous blood sample is most commonly used for Cancer Screening Profile. It is drawn from a vein, usually in the arm, using a needle and a collection tube.
