Biomarker
A measurable biological signal used to detect disease or predict treatment response.
What it is
A biomarker is a measurable sign in the body that can indicate the presence of a disease, such as cancer. It's like a warning flag that doctors can look for to help diagnose a condition. Biomarkers can also be used to predict how well a person might respond to a particular treatment.
How it works
Biomarkers are often found in bodily fluids like blood or urine, or in tissue samples taken from the body. They can be measured using tests like blood tests or imaging scans. In some cases, biomarkers are made up of proteins or other molecules that are produced by cancer cells, while in other cases, they're related to how the body responds to cancer.
Why it matters
Understanding biomarkers is important because it can help doctors make more accurate diagnoses and choose the best treatments for patients. Biomarkers can also help researchers learn more about how cancer works and develop new treatments. This can ultimately lead to better outcomes for people with cancer.
