Aid in early detection
For high‑risk individuals (family history, genetic syndromes), tumor marker screening can detect cancer at an earlier, more treatable stage.
Tumor markers are substances – often proteins – produced by cancer cells or by the body in response to cancer. They can be detected in blood, urine, or tissue samples. Tumor marker tests are essential tools for cancer screening, diagnosis, monitoring treatment response, and detecting recurrence. While not definitive for cancer on their own, they provide valuable information when combined with imaging, biopsy, and clinical evaluation.
Different tumor markers are associated with specific cancers – for example, PSA for prostate cancer, CA-125 for ovarian cancer, AFP for liver cancer, and CEA for colorectal cancer. Regular monitoring of these markers helps oncologists assess whether treatment is working, adjust therapies, and detect relapse early.
At Amytri, our tumor marker tests are performed using state‑of‑the‑art chemiluminescence immunoassay analysers, ensuring high sensitivity and specificity. Results are validated by experienced pathologists and shared with your oncologist or physician. We offer home sample collection for your convenience.
Tumor markers are powerful tools that complement imaging and biopsy – providing real‑time insights into cancer behaviour and treatment response.
For high‑risk individuals (family history, genetic syndromes), tumor marker screening can detect cancer at an earlier, more treatable stage.
Serial tumor marker levels help oncologists assess whether chemotherapy, immunotherapy, or targeted therapy is working – and adjust accordingly.
After successful treatment, rising tumor marker levels can indicate relapse – often before symptoms appear, enabling earlier intervention.
We offer a full range of tumor markers – individually or as panels – to support screening, diagnosis, and monitoring for various cancers.
Alpha‑fetoprotein (AFP) is elevated in hepatocellular carcinoma (liver cancer) and germ cell tumours (testicular, ovarian). Also used for neural tube defect screening in pregnancy.
Carcinoembryonic Antigen (CEA) is elevated in colorectal, lung, breast, and pancreatic cancers. Used for monitoring treatment and detecting recurrence.
CA‑125 is used for ovarian cancer screening in high‑risk women and monitoring treatment. Also elevated in endometriosis and other benign conditions.
CA 19‑9 is elevated in pancreatic, bile duct, and gastric cancers. Useful for monitoring treatment and detecting recurrence.
CA 15‑3 and CA 27‑29 are used to monitor breast cancer treatment and detect recurrence. Often used alongside imaging and other markers.
Prostate‑Specific Antigen (PSA) is the primary screening and monitoring tool for prostate cancer. Free PSA helps distinguish benign disease from cancer.
Calcitonin (medullary thyroid cancer), Thyroglobulin (thyroid cancer monitoring), Chromogranin A, and NSE (neuroendocrine tumours, small cell lung cancer).
Beta‑hCG is elevated in gestational trophoblastic disease, testicular cancer, and some ovarian germ cell tumours. Also used for pregnancy monitoring.
HE4 (Human Epididymis Protein 4), combined with CA‑125 in the ROMA (Risk of Ovarian Malignancy Algorithm) score, improves ovarian cancer risk assessment.
Fasting is usually not required. However, certain medications, recent infections, or benign conditions can affect marker levels. Inform our team about any medications or recent procedures.
A trained phlebotomist collects a venous blood sample. The process is quick and gentle. We also offer home sample collection for your convenience.
Tumor markers are measured using chemiluminescence immunoassay (CLIA) or electrochemiluminescence (ECLIA) – highly sensitive, specific methods. Results are reviewed by pathologists.
Reports are typically ready within 24–48 hours. We deliver them via WhatsApp or email with reference ranges and interpretive notes for your oncologist or physician.
Tumor markers are used in specific clinical contexts – always under the guidance of an oncologist or specialist.
If you have a strong family history of cancer or known genetic mutations (e.g., BRCA, Lynch syndrome), tumor markers may be part of your screening.
When cancer is suspected, tumor markers can support diagnosis alongside imaging and biopsy – providing additional evidence.
If you are undergoing chemotherapy, immunotherapy, or targeted therapy, serial tumor markers help assess response and guide dose adjustments.
After completing cancer treatment, regular tumor marker testing helps detect relapse early – often before clinical symptoms appear.
If you have symptoms (e.g., unexplained weight loss, persistent pain) or abnormal imaging, tumor markers can provide additional diagnostic clues.
Some tumor markers (like PSA and Gleason score, or CA-125 levels) help predict cancer aggressiveness and guide treatment intensity.
Dr. Abhishek oversees all tumor marker testing at Amytri, ensuring the highest accuracy and reliability. He works closely with medical and surgical oncologists, gynaecologists, urologists, and gastroenterologists to interpret complex marker patterns and guide further investigation – from imaging to biopsy and molecular testing.
Tumor marker testing can be an anxious time – having your partner or family member with you provides support, shared understanding, and a second set of ears for the results.
We welcome partners during sample collection and result discussions. They can ask questions, help remember the doctor's advice, and support you through the journey – whether it's screening, treatment, or surveillance.
Tumor markers are substances (usually proteins) produced by cancer cells or by the body in response to cancer. They can be detected in blood, urine, or tissue and help in screening, diagnosis, monitoring, and surveillance of cancer.
No, tumor markers alone cannot diagnose cancer definitively. They are used alongside imaging (CT, MRI, ultrasound), biopsy, and clinical evaluation. Elevated markers suggest the need for further investigation.
Fasting is usually not required for most tumor markers. However, some tests (like PSA) may be affected by recent ejaculation, prostate manipulation, or urinary tract infections – we will provide specific instructions.
Most tumor marker reports are ready within 24–48 hours. We deliver them via WhatsApp or email for quick access by you and your doctor.
Yes! We offer home sample collection for all tumor marker tests. A trained phlebotomist will visit you at your convenience.
A prescription is strongly recommended for tumor marker testing, as it is typically done in specific clinical contexts (screening, monitoring, surveillance). Your oncologist or physician will guide the appropriate tests based on your clinical history.
