HER2-Targeted Cancer Therapies Market Size and Forecast

The global HER2-targeted cancer therapies market was valued at USD 64.7 billion in 2025 and is projected to reach USD 123.8 billion by 2032, growing at a CAGR of 9.7%. Growth is driven by expanding HER2 testing, strong clinical efficacy of targeted biologics, increasing adoption of antibody–drug conjugates, and ongoing expansion into new tumor indications.

Market Overview

HER2-targeted cancer therapies are precision treatments developed to block HER2-driven signaling pathways that promote tumor proliferation and survival. These therapies include monoclonal antibodies that inhibit receptor activation, antibody–drug conjugates that deliver cytotoxic agents directly to HER2-positive cells, and small-molecule inhibitors that block downstream signaling. Accurate HER2 testing using IHC and ISH diagnostics is fundamental to therapy eligibility. The market is characterized by strong clinical differentiation, long treatment durations, and high therapy costs. Continuous clinical research expands usage into earlier treatment lines and combination regimens. Regulatory support for targeted oncology therapies accelerates market adoption.
