Breast Cancer Drugs Market to Reach USD 57.1 Billion by 2031 as Precision Oncology and Targeted Therapies Redefine Treatment Outcomes

AUSTIN, Texas and TOKYO, Dec. 17, 2025 /PRNewswire/ -- According to DataM Intelligence, the global Breast Cancer Drugs Market reached USD 32.4 billion in 2024 and is projected to expand to USD 57.1 billion by 2031, growing at a robust CAGR of 9.2% during the forecast period 2025–2031.

This sustained growth reflects a decisive transformation in breast cancer care, where treatment strategies are shifting from broad, cytotoxic approaches toward biomarker-driven, targeted, and immune-based therapies. Advances in molecular diagnostics, earlier detection, and personalized treatment regimens are enabling clinicians to significantly improve survival outcomes while reducing long-term toxicity.

By 2030, breast cancer therapeutics will be defined not by volume alone, but by clinical precision, durability of response, and lifecycle innovation across therapy lines.

Why Breast Cancer Therapeutics Are Entering a New Growth Phase

The expansion of the breast cancer drugs market is being driven by interconnected structural forces.

• Breast cancer incidence continues to rise globally, driven by aging populations, lifestyle factors, and improved screening programs. Breast cancer remains the most commonly diagnosed cancer among women worldwide, creating sustained demand for effective long-term treatment options.
• Treatment paradigms are becoming increasingly stratified. Instead of one-size-fits-all approaches, therapies are now selected based on hormone receptor status, HER2 expression, and emerging molecular signatures. This precision has expanded the use of targeted and combination therapies across early-stage and metastatic disease.
• Oncology innovation cycles have accelerated. Continuous pipeline development, label expansions, and novel mechanisms of action are extending treatment duration and increasing per-patient drug value.

As a result, breast cancer drugs have become one of the most strategically important segments within global oncology markets.

Market Segmentation Analysis

By Cancer Type

Hormone receptor-positive breast cancer represents the largest segment, accounting for approximately 64% of total market value in 2024, equivalent to USD 20.7 billion.

This dominance reflects the high prevalence of estrogen and progesterone receptor-positive tumors and the long duration of treatment using hormonal and targeted agents. Continuous innovation in CDK4/6 inhibitors and endocrine combinations continues to expand this segment.

HER2-positive breast cancer accounts for approximately 21% of the market, or around USD 6.8 billion.

Advances in HER2-targeted monoclonal antibodies, antibody-drug conjugates, and combination regimens have dramatically improved outcomes, transforming HER2-positive disease into a highly treatable subtype.

According to DataM Intelligence analysis, 'Hormone receptor-positive breast cancer will remain the largest revenue contributor through 2031, while HER2-positive and triple-negative segments will drive incremental growth through innovation'.

By Therapy

Targeted therapy is the leading therapeutic category, accounting for approximately 38% of total market revenue, or USD 12.3 billion in 2024.

These therapies deliver high clinical efficacy with improved tolerability and are increasingly used across multiple lines of treatment.

Hormonal therapy follows closely, representing about 27% of market value, or USD 8.7 billion.

Its long treatment duration and widespread use in early and advanced disease ensure sustained demand.

Chemotherapy accounts for approximately 22%, or USD 7.1 billion, reflecting its continued role in aggressive and late-stage disease despite growing competition from targeted approaches.

Immunotherapy contributes the remaining 13%, or roughly USD 4.3 billion.

While still emerging, immunotherapy is gaining traction, particularly in triple-negative breast cancer, and is expected to record the fastest growth rate through 2031.

According to DataM Intelligence Analysis, 'Targeted and immune-based therapies will increasingly displace conventional chemotherapy in value terms, even as combination regimens remain standard practice'.

By End User

Hospitals represent the largest end-user segment, accounting for approximately 46% of total market value, or USD 14.9 billion. Complex treatment protocols, infusion therapies, and inpatient oncology care drive this dominance.

Cancer centers account for around 29%, or USD 9.4 billion, reflecting the growing role of specialized oncology institutions in advanced and personalized treatment delivery.

Clinics and ambulatory surgical centers together represent approximately 18%, or USD 5.8 billion, supported by the shift toward outpatient care and oral therapies.
