Oncology-Based Molecular Diagnostics Market Set to Hit USD 6.12 Billion by 2034, Fueled by Precision Medicine and Biomarker Advancements

The global oncology-based molecular diagnostics market is set for steady growth, with its valuation rising from USD 3.66 billion in 2024 to USD 6.12 billion by 2034, expanding at a CAGR of 5.3% over the forecast period (2025–2034). Increasing demand for personalized oncology testing, growing cancer prevalence, and rapid advancements in genomic diagnostics are among the primary factors propelling market expansion.

Market Overview

Oncology-based molecular diagnostics refers to the use of molecular-level analysis—such as DNA, RNA, and protein profiling—to diagnose, monitor, and guide treatment decisions for cancer patients. This approach has transformed oncology by enabling clinicians to identify specific genetic mutations, detect biomarkers, and tailor therapies to individual patients.

The surge in cancer diagnostics technologies is supported by global efforts to improve early detection, enhance treatment efficacy, and reduce mortality rates. Governments, healthcare providers, and research institutions are increasingly adopting molecular diagnostic tools as part of national cancer screening programs. Furthermore, the integration of companion diagnostics in oncology is enabling targeted therapies that maximize patient outcomes while minimizing side effects.

Market Segmentation

The oncology-based molecular diagnostics market can be segmented by technology, application, and end-user.

By Technology

• Polymerase Chain Reaction (PCR) – Remains the dominant technology due to its high sensitivity, specificity, and widespread availability in clinical laboratories.
• Next-Generation Sequencing (NGS) – Rapidly gaining adoption for comprehensive genomic profiling, identifying rare mutations, and detecting multiple biomarkers in a single assay.
• In Situ Hybridization (ISH) – Essential for detecting gene amplification and chromosomal abnormalities, particularly in breast, lung, and cervical cancers.
• Other Technologies – Includes immunohistochemistry (IHC), microarrays, and digital PCR, offering additional molecular-level insights.

By Application

• Breast Cancer – Significant adoption of molecular assays for HER2, BRCA1/2, and other biomarkers guiding treatment.
• Lung Cancer – Growing demand for EGFR, ALK, KRAS, and PD-L1 testing to support targeted therapies.
• Colorectal Cancer – Increasing use of KRAS and NRAS mutation analysis for treatment selection.
• Prostate Cancer – Molecular diagnostics gaining ground for risk stratification and monitoring disease progression.
• Other Cancers – Includes leukemia, melanoma, and gastric cancer testing.

By End-User

• Hospitals & Clinics – Primary adopters due to their role in cancer diagnosis, treatment planning, and patient management.
• Diagnostic Laboratories – Growing role in outsourced testing services, especially for advanced NGS panels.
• Research Institutions – Active in biomarker discovery, validation studies, and clinical trials for novel oncology diagnostics.
