Prostate cancer is the second most common cancer among men worldwide and the most common in the Czech Republic. The incidence of the disease in Czechia has risen by as much as 70 percent since the early 1990s. Martina Benešová, a young Czech researcher, is part of a team at the German Cancer Research Center in Heidelberg which developed a revolutionary new treatment for patients with a very advanced stage of prostate cancer for whom other treatments had proved ineffective. I spoke to her and started by asking what is new about PSMA-617 compared to previous prostate cancer treatment methods.
