Metastatic prostate cancer cases skyrocket: More lax screening rather than more aggressive disease?

The number of new cases of metastatic prostate cancer climbed 72 percent in the past decade from 2004 to 2013, reports a new study. The report considers whether a recent trend of fewer men being screened may be contributing to the rise, or whether the disease has become more aggressive -- or both. The highest increase is among men ages 55 to 69, who could benefit the most from screening and early treatment.
