Cancer biomarker detection

Definition

Cancer biomarker detection refers to the identification of biological markers in the body that indicate the presence of cancer. These biomarkers can be molecules found in blood, other body fluids, or tissues that signify a disease process, particularly cancer. By accurately detecting these biomarkers, clinicians can diagnose cancer earlier, tailor treatments to individual patients, and monitor treatment response and disease progression.

5 Must Know Facts For Your Next Test

1. Cancer biomarkers can include proteins, nucleic acids, or other molecules that change in concentration or structure when cancer is present.
2. The use of cancer biomarker detection technologies has advanced significantly with the development of genomic and proteomic techniques.
3. Detecting biomarkers can aid not just in diagnosis but also in predicting how well a patient will respond to specific treatments.
4. Some common biomarkers include prostate-specific antigen (PSA) for prostate cancer and HER2/neu for breast cancer, which help guide treatment decisions.
5. Research continues to uncover new biomarkers that could lead to breakthroughs in personalized medicine, enhancing precision in cancer care.

Review Questions
