Tumour marker testing

Tumor marker testing are generally excluded from most medical insurance policies, unless you have previously been diagnosed with the specific cancer in question. In this case, coverage is typically provided under the Oncology benefit, or if you have a wellness/health check benefit which includes tumor marker testing. Tumor marker testing is a diagnostic tool that measures the amount of certain substances in tissue, blood, urine, or other body fluids. These substances, known as tumor markers, are typically proteins made by both normal cells and cancer cells, but are present in higher amounts in cancer cells.

In addition to measuring the presence of these proteins, genetic changes in tumor tissue, such as gene mutations, patterns of gene expression, and other changes in tumor DNA, are also being used as tumor markers. A tumor marker test is usually done in conjunction with other diagnostic tests, such as biopsies or imaging, to help diagnose some types of cancer. It may also be used to help plan treatment or determine the effectiveness of treatment, give a likely prognosis, or detect if cancer has recurred or spread to other parts of the body.

It is important to note that tumor marker testing is not always a definitive diagnostic tool and should be used in conjunction with other diagnostic tests. Additionally, false positive and false negative results can occur, and it is important to consult with a healthcare provider to understand the results and their implications.
