Brachytherapyโan image-guided, minimally invasive form of internal radiation therapyโhas become a frontline modality for prostate, gynecological, skin, and breast cancers because it maximizes tumoricidal dose while sparing healthy tissue. With global Brachytherapy market size estimated at USD 1.12 billion in 2025, the sector is riding a growth outlook of ~5.6% CAGR (2026-2033), propelled by an aging population, earlier cancer detection, and a shift toward value-based, outpatient oncology models. The market forecast is further under-pinned by regulatory greenlights for high-dose-rate (HDR) afterloaders, reimbursement parity with external-beam therapy, and hospital consolidation that favors single-session treatments. Scope includes applicators, electronic or isotope-based sources, treatment-planning software, and associated maintenance services; synonyms range from โinternal radiotherapyโ and โseed implantationโ to โcurietherapy.โ
