The global estrogen receptor positive (ER+) breast cancer treatment market was valued at USD 19.8 billion in 2023 and is projected to reach USD 33.7 billion by 2030, expanding at a CAGR of 7.89% from 2024 to 2030. This growth is propelled by advancements in drug development, increased awareness and screening, rising incidence rates of breast cancer, and strategic industry collaborations.

These factors are reshaping the ER+ breast cancer treatment landscape, promoting the introduction of innovative therapies, enhancing clinical outcomes, and broadening patient access to advanced treatment options. According to the World Health Organization (WHO), breast cancer is the most prevalent cancer among adults, with more than 2.3 million new cases each year, and remains a leading cause of cancer-related deaths among women, especially in low- and middle-income regions.

A major catalyst for market growth is ongoing innovation in drug development. Emerging therapies—including new aromatase inhibitors, selective estrogen receptor degraders (SERDs), and targeted agents—are transforming treatment approaches. A notable example is the U.S. FDA's approval of Orserdu in January 2023, a novel oral drug for treating metastatic ER-positive, HER2-negative breast cancer with an ESR1 mutation. Such breakthroughs highlight the industry's emphasis on more precise and effective treatment modalities.

The escalating global incidence of breast cancer further accelerates demand for ER+ treatments. According to the American Cancer Society, breast cancer is the most frequently diagnosed cancer in women, with an estimated 310,720 new cases expected in the U.S. in 2024. This trend underscores the need for continued investment in the development of advanced therapies to meet increasing clinical demands.

Rising awareness of breast cancer symptoms and the importance of early detection has encouraged greater participation in screening programs. Initiatives by organizations such as Susan G. Komen and the American Cancer Society have significantly contributed to promoting mammography and self-examination, which, in turn, increases demand for targeted ER+ treatments following diagnosis.
