The global solid tumor testing market size was valued at USD 29.68 billion in 2025 and is projected to grow from USD 32.05 billion in 2026 to USD 59.23 billion by 2034, registering a CAGR of 7.98% during the forecast period from 2026 to 2034. North America dominated the solid tumor testing market with a market share of 41.8% in 2025.
In cancer, the accumulation of abnormal tissues can result in the formation of solid tumors. Unlike cystic or liquid tumors, solid tumors do not contain any fluid. Solid tumors can be either benign or malignant, depending on their characteristics. Treating solid tumors can be challenging and requires coordinated efforts from various medical professionals, such as surgeons, radiologists, radiation specialists, oncologists, and others. Consequently, chemotherapy, radiation therapy, and operation are the primary treatment modes for most solid tumors. Solid tumors are heterotypic collections of various cell types, including cancer cells, cancer stem cells, connective-tissue cells, and immune cells. Depending on their location, solid tumors can be classified as benign or malignant. Surgery is the treatment option that is currently considered to be the most effective for solid malignant tumors.

Liquid Biopsy Is Expanding Comprehensive Tumor Profiling
The Solid Tumor Testing Market is shifting toward blood-based liquid biopsy alongside conventional tissue testing. Liquid biopsy analyzes tumor-derived material circulating in blood, helping clinicians obtain molecular information when tumor tissue is difficult to collect or insufficient. Newer platforms are also combining genomic and epigenomic signals to increase the amount of information obtained from one sample. This supports broader use of testing for treatment selection and repeated disease assessment. The approach does not fully replace tissue biopsy, but it creates a more flexible testing pathway for advanced cancers. As targeted therapies expand, demand is increasing for blood-based platforms capable of identifying multiple actionable biomarkers through one test.
In May 2026, the FDA approved Guardant360 Liquid CDx, which assesses a genomic footprint 100 times wider than the previous Guardant360 CDx and integrates genomic and epigenomic profiling.
Expanding Targeted Therapies Are Making Biomarker Testing Essential
Growth in targeted cancer treatment is a major driver because many therapies work only when a tumor contains a specific molecular alteration. Solid tumor testing helps identify these biomarkers and match eligible patients with appropriate treatments. Companion diagnostics therefore become directly linked to therapy adoption, creating recurring demand as new cancer drugs and indications receive regulatory approval. Testing is particularly important in cancers such as lung, breast, and colorectal cancer, where molecular characteristics increasingly influence treatment selection. As drug developers identify additional actionable mutations, diagnostic companies can expand existing platforms through new companion-diagnostic claims rather than developing completely separate testing systems for every therapy.
In January 2026, FDA approval expanded Guardant360 CDx into colorectal cancer for identifying BRAF V600E-mutant metastatic patients eligible for an encorafenib-based treatment combination.
Limited Tissue and Unequal Testing Access Restrict Wider Adoption
Solid tumor testing can be restricted when obtaining sufficient tumor material is difficult. Some tumors are hard to reach safely, while small biopsy samples may contain too little usable tissue for extensive molecular analysis. Testing availability also varies between hospitals, and insurance coverage can depend on whether evidence supports the clinical value of a particular assay. These factors can delay or prevent comprehensive profiling even when testing could help treatment decisions. Liquid biopsy reduces some tissue limitations, but negative blood-test results may still require confirmation using tumor tissue. Wider market adoption therefore depends on improving sample efficiency, laboratory access, reimbursement, and clinically validated testing pathways.
In June 2026, updated FDA information for FoundationOne Liquid CDx continued to state that negative plasma results should be confirmed with an FDA-approved tumor-tissue test when feasible.
Repeated ctDNA Testing Is Opening a New Monitoring Market
An important opportunity is moving solid tumor testing beyond initial diagnosis and treatment selection toward repeated molecular monitoring. Tumors can change during therapy, meaning a biomarker profile obtained earlier may no longer represent the current disease. Blood-based circulating tumor DNA testing makes repeat sampling easier than repeated invasive tissue biopsies and can potentially identify emerging mutations before conventional imaging shows progression. This creates recurring testing demand throughout a patient's treatment journey rather than a single test at diagnosis. Diagnostic companies can therefore develop monitoring platforms, companion diagnostics, and longitudinal data services that connect molecular changes with treatment decisions across breast, lung, colorectal, and other solid cancers.
In September 2026, FDA approval linked Guardant360 CDx with repeat testing every three months to detect emerging ESR1 mutations in advanced breast cancer before clinical or radiographic progression.
Tumor Heterogeneity Makes Molecular Results Harder to Interpret
A major challenge is that cancer cells within the same patient do not always contain identical biomarkers. One biopsy samples only part of a tumor at a particular time, while molecular characteristics can also change as cancer progresses or responds to treatment. Consequently, a detected biomarker may describe only part of the disease, and a previously obtained result may become outdated. Larger sequencing panels generate additional information, but not every detected genomic alteration has an approved treatment or established clinical meaning. Laboratories and clinicians therefore need strong bioinformatics and interpretation capabilities to separate actionable findings from uncertain ones while deciding when repeat or complementary testing is appropriate.
In July 2025, the FDA approved the Oncomine Dx Express Test for solid tumors, but specified that genomic findings outside its approved companion-diagnostic indications are not prescriptive or conclusive for a particular therapy.
