Brain Cancer Diagnostics Market Size and Forecast, 2025-2035 (USD Billion)
Sources: Expert interviews, secondary sources, Precedence Research database, and Precedence Research analysts.
The brain cancer diagnostics market is expected to increase from USD 3.92 billion in 2025 to USD 6.51 billion in 2035 due to a higher number of brain tumours and metastases scans, as well as additional molecular testing by pathologists to define tumours based on WHO criteria. AI algorithms for tumour volume and methylation pattern analysis increase the market size to USD 5.05 billion in 2030 while maintaining CAGR at 5.20% in 2026-2035.
- Analyst View: We developed our estimate based on brain tumour and follow-up scan case numbers and associated cost of imaging procedures, biopsy, histopathology, and molecular testing, as well as revenues from imaging equipment and software sales. Case numbers include primary brain tumour incidence cases as well as metastatic brain tumours from lung, breast, and melanoma cancer incidence, plus monitoring scans for treated patients. This figure was then benchmarked against the neuro-imaging and oncology diagnostics revenues of the leading firms and external projections, which put us slightly above the comparables for our base year.
Market Trends
- Molecular markers are now required to classify many brain tumours.
- DNA methylation classifiers are refining tumour diagnosis.
- AI software measures tumour volume on MRI over time.
- Blood-based glioma tests are moving through regulatory review.
- Advanced MRI sequences help separate tumour from treatment effects.
- Brain metastasis screening is rising with longer cancer survival.
Drivers, Restraints and Opportunities
Drivers
Cases of brain tumours and brain metastases have been on the rise due to the aging population and survival of patients with other forms of cancer. The World Health Organization's classification of central nervous system tumours involves the use of molecular markers; therefore, there is an increase in the number of tumours that need genetic and methylation analysis. There is no doubt that MRI is very important in diagnosis, surgical intervention, and monitoring, and now better sequences and artificial intelligence have improved its accuracy.
Restraints
The cost of advanced MRI machines and molecular assays makes them inaccessible in many nations. Tumour biopsies are invasive procedures and cannot always be performed, which hinders histopathological assessment. It is challenging to differentiate tumour growth from the impact of treatment interventions in imaging. Reimbursements for methylation assays and artificial intelligence tools remain limited. The shortage of neuroradiologists and neuropathologists delays the diagnosis.
Opportunities
Blood and cerebrospinal fluid tests may aid the detection and monitoring of brain tumours in a non-invasive manner. Artificial intelligence imaging software may standardize tumor measurement and reporting. Methylation classifiers provided through laboratory services will become available even in facilities that do not have neuropathology specialists. The increase in MRI capacity in Asia and Latin America widens access.
Market Segmentation: 2025 Share and Value
Brain Cancer Diagnostics Market By Diagnostic Type 2025 Share & Size
Sources: Expert interviews, secondary sources, Precedence Research database, and Precedence Research analysts.
Imaging formed 58.40% (USD 2.29 billion) of the market in 2025, as MRI (with contrast, perfusion, and spectroscopy sequences) and CT imaging modalities are used to detect, localize, measure, and monitor the progress of the tumour in the brain. AI-based software that can segment the tumours and measure the tumour volumes is proving useful in MRI interpretations and response assessment to treatment. Biopsy and histopathology formed 18.60% (USD 0.73 billion) and confirm the diagnosis and tumour grade, whereas molecular testing formed 14.20% (USD 0.56 billion) and is the fastest-growing segment since the criteria by WHO now require markers, such as IDH, 1p/19q, and MGMT, as well as DNA methylation classifiers. Lumbar puncture and CSF analysis formed 4.60% (USD 0.18 billion) for lymphoma and leptomeningeal disease, and other methods, including blood tests, formed 4.20% (USD 0.16 billion).

Brain metastases represented 34.60% (USD 1.36 billion) in 2025 owing to the fact that brain metastases are much more frequent compared to primary brain tumours, and people who have been diagnosed with lung, breast, and melanoma cancer undergo frequent brain imaging. Gliomas and glioblastoma make up 28.40% (USD 1.11 billion) and require extensive imaging and molecular testing for proper diagnosis and treatment, making it the most valuable primary brain tumours segment. Meningiomas represented 18.20% (USD 0.71 billion), pituitary tumours 9.60% (USD 0.38 billion), and other brain tumours 9.20% (USD 0.36 billion).
Brain Cancer Diagnostics Market by End User 2025 Share & Size
Sources: Expert interviews, secondary sources, Precedence Research database, and Precedence Research analysts.
Hospitals contributed 61.40% (USD 2.41 billion) of market revenues in 2025 because diagnosis of brain tumours is done through advanced MRI, neurosurgical procedures for biopsies, and pathology studies, which are mostly carried out in hospitals and specialized cancer treatment centers. Diagnostic centers made up 27.80% (USD 1.09 billion) due to their role in carrying out outpatient MRI, CT, and sending tests out for molecular studies, which has increased due to imaging taking place outside the hospital setting. Others represent 10.80% (USD 0.42 billion).
- Analyst View: Market values in the segments were calculated through mapping of diagnostics and follow-ups on a per-tumour basis and then calculating their costs based on imaging and molecular tests and dividing them on a care setting basis. Imaging will continue to lead in the market because every patient has to undergo multiple scans, whereas molecular tests have high values per case.

Research Methodology
The brain cancer diagnostics market was segmented into imaging, biopsy & histopathology, molecular testing, cerebrospinal fluid analysis, and associated software used for diagnosing and monitoring brain tumors globally. The base year 2025 was derived bottom-up by assessing the number of brain tumor diagnoses and follow-up imaging and testing conducted, their volume and cost, and validating the top-down by assessing the revenue generated by leading players through their neuroimaging and oncology diagnostic products. Values of segments, regions, and companies were allocated from diagnostic methods, tumor type, end-users, and diagnostic capabilities of regions. Estimates were corroborated by comparing company reports, regulatory and industry data, and third-party estimates, and all those inputs that could not be reconciled were ignored. All values pertaining to segments, regions and companies were harmonized to the base year 2025, and the forecast for 2026 to 2035, using a constant CAGR based on 2025, was reworked and validated.
Analyst View: Overall Market
Imaging is the dominant technology in the brain cancer diagnostics market, with molecular classification and artificial intelligence contributing value on a case-by-case basis. Our forecast connects demand to the number of tumours, imaging, testing volumes and procedure costs, so it follows cancer prevalence rates, imaging capabilities and molecular testing rates. Upside is mainly from molecular classification, AI imaging and liquid biopsy, while risks come from high costs, low reimbursements and specialist shortages.
