HER2-Negative Breast Cancer – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033
Breast cancer cells lacking abnormal levels of HER2 proteins are classified as HER2-negative. This subgroup represents the largest and most diverse category, encompassing both hormone receptor (HR)-positive tumors. For HR-positive and HER2-negative metastatic disease, current guidelines recommend prioritizing endocrine therapy over chemotherapy as the initial treatment option. However, the management of HR-positive, HER2-negative patients primarily aims at control rather than cure, with overall 5-year survival rates falling between 30% and 45%. The age-adjusted rate of HR-negative/HER2-negative (HR-/HER2-) and HR-positive/HER2-negative (HR+/HER2-) breast cancer cases is estimated to be 13.2 and 87.2 per 100,000 women, respectively. · In the United States in 2023, approximately 20,380 individuals, comprising 11,410 males and boys and 8,970 females and girls, are expected to receive a diagnosis of AML across all age groups.
