Prostate cancer is the third most common type of cancer in the United States, after breast cancer and lung cancer. In 2018 alone, 164,690 individuals were diagnosed with prostate cancer, accounting for nearly 10% of all new cancer cases, and 29,430 deaths were attributed to the disease.

More than 98% of patients with prostate cancer survive ≥5 years; however, the 5-year survival rate drops to 30% for patients with metastatic disease.
