Who actually dies from prostate cancer? Additional observations

Earlier today we reported on a recent publication based on data from the CaPSURE registry database, which stated that, among men enrolled in that database, men died sooner from their prostate cancer after they progressed to having metastatic disease over time (median survival, 2.4 years from onset of metastasis) than died from their prostate cancer if they were initially diagnosed with metastatic disease (median survival, 5.3 years). … READ MORE …
