The global liquid biopsy market size is estimated at US$ 4.72 billion in 2023 and is forecasted to expand rapidly at a CAGR of 18% to reach a valuation of US$ 24.70 billion by 2033, according to a newly released market study of liquid biopsy by Fact.MR, a market research and competitive intelligence provider. This growth is driven by the increasing demand for non-invasive cancer diagnostics, advancements in next-generation sequencing (NGS) technologies, and the rising prevalence of cancers worldwide. Liquid biopsies, which analyze circulating tumor DNA (ctDNA), RNA, and other biomarkers in blood or fluids, offer real-time insights into tumor dynamics, enabling early detection, therapy selection, and monitoring without the risks of traditional tissue biopsies.

Market Segmentation and Trends:

The liquid biopsy market is segmented by offering, sample, biomarker, technology, application, and region, providing a comprehensive view of its dynamics. Offerings include assay kits, instruments, and software & services, with assay kits leading due to their role in standardized testing. Samples encompass blood, urine, saliva, and others, with blood dominating for its accessibility to ctDNA. Biomarkers include circulating tumor cells (CTCs), ctDNA, extracellular vesicles, and circulating tumor RNA, with ctDNA gaining traction for mutation detection. Technologies comprise NGS, PCR, and others, with NGS projected to grow at 19% CAGR for its high sensitivity.

Applications span routine screening, patient work-up, therapy selection, and treatment & recurrence monitoring, with therapy selection expanding rapidly for personalized medicine. Regionally, North America holds the largest share, while Asia Pacific is the fastest-growing at over 20% CAGR. Trends include the integration of AI for data analysis, multi-omics approaches, and the development of ultra-sensitive assays for early-stage cancer detection.

Driving Factors Behind Market Growth:

The liquid biopsy market is propelled by several key factors. The global cancer burden, with 20 million new cases in 2022 and projected 35 million by 2050, drives demand for non-invasive diagnostics. Liquid biopsies enable early detection and monitoring, reducing mortality through timely interventions. Advancements in NGS and PCR technologies offer high sensitivity for low-abundance biomarkers, facilitating precision oncology. The shift toward minimally invasive procedures minimizes patient discomfort and risks, boosting adoption in screening programs. Regulatory approvals, like FDA's for Guardant's Shield test in 2024, validate clinical utility.

Rising investments in biotech R&D, coupled with collaborations for companion diagnostics, accelerate innovation. The aging population and lifestyle factors increasing cancer incidence further fuel growth. Additionally, the cost-effectiveness of liquid biopsies compared to tissue biopsies supports their integration into healthcare systems, addressing accessibility in underserved regions.
