Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [ 2 ] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging.
The Oncotype DX® breast cancer assay is one such test used to predict the likelihood of breast cancer recurrence. This test is intended for women with early-stage (Stage I or II), node-negative, estrogen receptor -positive (ER+) invasive breast cancer who will be treated with hormone therapy .
The CEA blood test is not reliable for diagnosing cancer or as a screening test for early detection of cancer. [8] Most types of cancer do not result in a high CEA level. [9] Serum from individuals with colorectal carcinoma often has higher levels of CEA than healthy individuals (above approximately 2.5ng/mL). [10]
In New York State, Litvack found champions in the legislature to push forward a bill enhancing insurance coverage for supplemental breast cancer screening for those with New York State health plans.
Mammography is a common screening method, since it is relatively fast and widely available in developed countries. Mammography is a type of radiography used on the breasts. .

Breast cancer, prostate cancer, and colorectal cancer are examples of cancer types that are prone to overdiagnosis. [10] The consequences of overdiagnosis and overtreatment resulting from cancer screening can lead to a decline in quality of life, due to the adverse effects of unnecessary medication and hospitalization. [10] [12] [13]
In addition to these common markers, there are prognostic markers specific to different cancer types. For example estrogen level, progesterone and HER2 are markers specific to breast cancer patients. There is evidence showing that genes behaving as tumor suppressors or carcinogens could act as prognostic markers due to altered gene expression ...
