HER2-Positive Breast Cancer Market Key Players, Share and Forecast Outlook
IntroductionThe HER2-positive breast cancer market represents one of the most advanced and innovation-driven oncology segments globally. HER2-positive breast cancer is a subtype characterized by overexpression of the human epidermal growth factor receptor 2 (HER2) protein, which promotes the growth of cancer cells. Although once associated with aggressive disease progression and poor prognosis, the introduction of targeted therapies has dramatically improved survival rates.
Over the next decade, the market will be shaped by a robust drug pipeline, increased personalized medicine adoption, and the emergence of next-generation HER2-targeted agents such as antibody-drug conjugates (ADCs) and bispecific antibodies. Rising incidence rates, early diagnosis programs, and expanded treatment access in emerging economies will also drive growth.
