The Types segment classifies diagnostic technologies into four major groups: molecular testing, imaging, histopathology, and liquid biopsy. Molecular testing—covering PCR‑based mutation panels, next‑generation sequencing, and gene‑expression profiling—captures the shift toward precision oncology and contributes the largest share of the market due to its role in therapy selection. Imaging technologies, including dermoscopy, confocal microscopy, and whole‑body PET/CT, provide non‑invasive visual assessment and are essential for both detection and staging. Histopathology remains a cornerstone, with immunohistochemistry and digital pathology offering definitive tissue‑based confirmation. Liquid biopsy, a rapidly emerging sub‑type, leverages blood‑based biomarkers such as ctDNA and exosomal RNA to enable minimally invasive monitoring. Each type adds distinct value to the overall market size: molecular and imaging dominate revenue, while histopathology and liquid biopsy provide complementary depth and future growth potential within the market taxonomy.
