What is Tumor DNA Sequencing?
Tumor DNA sequencing — also called somatic tumor profiling — analyzes the specific genetic mutations present in your cancer cells. Unlike germline testing (which looks at inherited mutations passed down through families), somatic profiling focuses exclusively on what is driving your tumor, enabling precision treatment selection. Every tumor is genetically unique; somatic sequencing reveals that unique molecular fingerprint.
A comprehensive somatic panel reads hundreds of cancer genes simultaneously from your tumor tissue (FFPE biopsy) or a blood draw (liquid biopsy). The resulting report classifies mutations by clinical actionability — Tier 1 (FDA-approved targeted therapy available), Tier 2 (clinical trial data), and resistance markers — giving your oncologist a clear, prioritized treatment roadmap. BigOHealth offers tumor DNA sequencing in India with full molecular oncologist interpretation, TMB/MSI analysis, and clinical trial matching, coordinated through India's leading molecular diagnostic labs.

Why Tumor DNA Sequencing Matters
Every tumor has a unique mutation profile. Somatic sequencing maps it precisely — turning a guesswork chemo plan into a gene-matched, evidence-backed treatment strategy.

FDA-approved targeted drugs matched via somatic biomarkers
Match mutations to targeted drugs
Identifies Tier 1 driver mutations with approved targeted therapies — EGFR, ALK, BRAF, KRAS G12C, HER2 and more — replacing empiric chemo with a precise drug match.
Catch resistance before progression
When first-line therapy starts failing, resistance mutations like T790M or MET amplification are already accumulating. Somatic sequencing finds them early so the next treatment is chosen correctly.
Unlock immunotherapy access
TMB-High and MSI-H tumors respond to checkpoint inhibitors like pembrolizumab. Somatic profiling identifies these biomarkers from the same single test.
Open clinical trial eligibility
Most precision oncology trials require documented somatic mutation status. Tumor DNA sequencing is often the only pathway to trial enrollment.
Avoid ineffective treatments
Knowing which mutations are absent is as valuable as knowing which are present — ruling out therapies that won't work saves time, money, and toxicity.

What will your tumor sequencing result say?
Your somatic profiling report classifies every detected mutation by clinical evidence level. The tier system tells your oncologist how to act on each finding.
Tier 1 — Actionable
Mutations with FDA-approved targeted therapies or strong clinical guideline support (e.g., EGFR exon 19 del → osimertinib). Your oncologist can act on these immediately.
Tier 2 — Investigational
Mutations with promising clinical trial data or off-label evidence. May open access to trials or compassionate use therapies.
Resistance Mutations
Secondary alterations (T790M, C797S, MET amplification) explaining why a current targeted therapy is losing effectiveness.
TMB Score
Tumor Mutational Burden — TMB-High (≥10 mut/Mb) predicts response to checkpoint inhibitors even without a specific targetable mutation.
MSI Status
MSI-High tumors respond well to pembrolizumab — critical biomarker for immunotherapy eligibility across tumor types.
VUS
Variants of Unknown Significance — detected mutations where clinical impact is still being studied. Not actionable today, tracked for reclassification.

Somatic vs Germline: Understanding the Difference
If somatic profiling detects a potentially hereditary mutation, genetic counseling helps you understand family implications.
Somatic-Germline Overlap
Some mutations found in tumor tissue (e.g., BRCA1/2) may also be inherited — counselors identify which ones need germline follow-up
Family Risk Evaluation
Determine whether family members should pursue germline testing based on somatic findings

Frequently Asked Questions
Answers for both first-time patients and those who already have a Tumor DNA Sequencing report in hand.
Tumor DNA sequencing (somatic profiling) analyzes the specific genetic mutations present in your cancer cells. Unlike germline testing, it focuses on what's driving your tumor — identifying actionable targets for therapy and resistance mutations to guide treatment decisions.
Somatic tumor sequencing analyzes mutations acquired by cancer cells (not inherited), while germline testing detects inherited mutations present in all cells. Tumor sequencing is used for therapy selection; germline testing is used for hereditary risk assessment. Both can be complementary.
Tumor DNA sequencing detects driver mutations, resistance mutations, copy number alterations, gene fusions, microsatellite instability (MSI), and tumor mutational burden (TMB) — all of which guide targeted therapy, immunotherapy, and clinical trial selection.
Most somatic tumor profiling reports are delivered in 14–21 business days. The timeline includes tumor tissue retrieval, DNA extraction, comprehensive panel sequencing, bioinformatics analysis, and expert molecular pathology review.
The primary sample is FFPE (formalin-fixed paraffin-embedded) tumor tissue from a biopsy or surgical specimen. Liquid biopsy using blood (ctDNA) is an alternative when tissue is unavailable or repeat biopsy is not feasible.
Yes. Resistance mutations are a key finding in tumor sequencing. When a targeted therapy or chemotherapy stops being effective, repeat sequencing can identify secondary mutations driving resistance and guide the next line of treatment.
Tumor DNA sequencing is most impactful in lung, colorectal, breast, ovarian, gastric, pancreatic, bladder, and melanoma cancers. It's particularly valuable when standard therapies have failed or when targeted therapy eligibility is uncertain.
