Prostate cancer is the second most common cancer among men, according to the American Cancer Society. It's also one of the trickiest cancers to diagnose and treat.
In recent years, cancer immunotherapy has been effective in treating patients with immunogenic, or so-called "hot" tumors with increased levels of inflammation and the presence of immune cells in and around the tumors.
Cancer researchers say they have established a new, life-extending treatment option for men with prostate cancer that has spread and become resistant to hormone therapy.
