Genomic testing reveals the molecular blueprint of a patient's tumor. By identifying specific mutations, gene fusions, and biomarkers, oncologists can select therapies proven to work against those exact targets.

β€œGenomic testing transforms cancer treatment from guesswork to precision.”

Types of Genomic Tests for Cancer

  • Next-Generation Sequencing (NGS)

    Analyzes hundreds of cancer-related genes simultaneously from tumor tissue. Standard panels include FoundationOne CDx and Tempus xT.

  • Liquid Biopsy (ctDNA)

    Detects tumor DNA fragments circulating in blood. Non-invasive alternative when tissue biopsy is difficult. Guardant360 and FoundationOne Liquid CDx.

  • IHC & FISH

    Immunohistochemistry and fluorescence in-situ hybridization detect specific proteins or gene amplifications (HER2, PD-L1, ALK).

  • MSI / TMB Testing

    Microsatellite instability and tumor mutational burden predict immunotherapy response across cancer types.
