Cancer Antigens & Antibody Detection — NEET Biology
✅ Asked in NEET 2021Antibodies against cancer-specific antigens are also used for detection of certain cancers. Techniques of molecular biology can be
NTA tests whether students understand that antibodies against cancer-specific antigens are molecular markers used to detect and diagnose certain cancers. These tumor-associated antigens trigger antibody production, allowing doctors to use serological tests for cancer screening. Students often confuse this with tumor suppressor genes or oncogenes, or mistake antibodies as treatments rather than diagnostic tools. Key point: Antibodies here are detection agents, not therapeutics. Remember—cancer-specific antigens are abnormal proteins present on tumor cells; detecting antibodies against them helps identify cancer before symptoms appear. This concept bridges immunology with oncology and is crucial for understanding modern diagnostic techniques in medicine.
For effective treatment of the disease, early diagnosis and understanding its pathophysiology is very important. Which of the following molecular diagnostic techniques is very useful for early detection? (NEET 2021)
