In more advanced breast cancer, which markers are elevated?

Explanation:
In advanced breast cancer, markers that reflect tumor burden in the body tend to rise. CA 15-3 is the most widely used marker for breast cancer and its levels correlate with disease burden and progression. CA 549 is another breast-associated marker that can be elevated in more advanced disease. Together, these two markers are commonly seen as elevated in advanced breast cancer and are useful for monitoring treatment response and disease course (not for screening or initial diagnosis). The other pairings mix markers not typically linked to breast cancer progression. CEA can be elevated in breast cancer but pairing it with AFP—an marker more associated with liver and germ cell tumors—doesn’t fit the typical pattern. AFP and CA 125 point more toward liver/germ cell or ovarian processes. PSA is a prostate cancer marker, not breast cancer.
