A 7-year CAGR of 8.5 percent through 2032 projects the market to approximately USD 67.5 billion, driven by ADC pipeline expansion, hormonal therapy growth, and continued oncology biosimilar entry. Buyer Power Score of -2.6, supplier-favoring. > **Analyst Take.** Our view: the consensus 8.5 percent CAGR is credible but front-loaded
