280K US cases/yr · $4.0B Global Hormonal Oncology (1999)
Breast cancer and prostate cancer are the two most commonly diagnosed cancers in the United States and were central targets of oncology drug development at the time of the 1998 Astra-Zeneca merger. According to the National Cancer Institute Cancer Statistics resource, the most frequently diagnosed cancers include breast cancer, prostate cancer, and lung and bronchus cancer. Breast cancer is the most common cancer overall, and prostate cancer ranks second in estimated new cases among men. Prostate cancer, lung cancer, and colorectal cancer together account for an estimated 48 percent of all cancers diagnosed in men, making prostate cancer a leading diagnosis in the male population. In women, breast cancer is similarly dominant and is one of the three most common cancers diagnosed alongside lung cancer and colorectal cancer. The combined public health impact of breast cancer and prostate cancer therefore spans both sexes, adult age groups, and a wide range of clinical settings, from screening and early detection through locally advanced and metastatic disease. Although overall cancer death rates in the United States have declined since the early 1990s, breast cancer and prostate cancer continue to contribute substantially to new cancer diagnoses each year and remain major drivers of oncology research, clinical trial activity, and pharmaceutical investment in novel targeted and endocrine therapies.
Foundation for AZ's later dominance (Tagrisso, Lynparza, Enhertu, Imfinzi). Arimidex replaced tamoxifen as adjuvant SOC.
