Death statistics are not a good measure in this case. The large majority of prostate cancer is very slow growing and occurs late in life. The goal of treatment is not to cure- just to slow it down. Many of those deaths are nearly at the age they would have died anyway and had a full life because of the less-aggressive treatment. Most people will live another 15+ years.

That stands in stark contrast to lung cancer, which has a median survival time of ~15 months. Pancreatic cancer usually kills you in less than a year. Colon cancer is better, but still only ~6 years. Leukemia and Lymphoma can occur in middle age or even in early childhood, and rob an entire lifetime.
