Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]
The objective of this study was to compare different tumor markers and their diagnostic value. The tumor markers tested in this experiment were CA 19-9, CA 242 and CEA tumor markers. The data revealed that although each marker have its own level of specificity and correspond to a cancer, all three makers together increase diagnostic value. [7]
Levels or presence of biomarker should readily distinguish between normal, cancerous, and precancerous tissue; Effective treatment of the cancer should change the level of the biomarker; Level of the biomarker should not change spontaneously or in response to other factors not related to the successful treatment of the cancer
However, there is a chance cancer may sometimes come back after a drug treatment or chemotherapy. There are three primary treatments for most cancers, chemotherapy, radiotherapy and immunotherapy.
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
When a malignant tumor is found by the presence of a tumor marker, the level of marker found in the body can be monitored to determine the state of the tumor and how it responds to treatment. If the quantity stays the same during treatment it can indicate that the treatment isn't working, and an alternative treatment should be considered.
New research links omega-6 fatty acids, commonly found in seed oils, and colon cancer growth. But there’s more to the story—and study if you read it carefully.
This occurs most commonly after the treatment of lymphomas and leukemias and in particular when treating non-Hodgkin lymphoma, acute myeloid leukemia, and acute lymphoblastic leukemia. [ 2 ] [ 3 ] This is a potentially fatal complication and people at an increased risk for TLS should be closely monitored while receiving chemotherapy and should ...
