Former U.S. President Joe Biden’s prostate cancer has spread to other parts of his body and is causing him pain, even as he continues to speak out on public issues. His son Hunter Biden said in an interview with the BBC broadcast late on Friday that his father's condition was very sad to watch. The younger Biden says “the cancer has spread, metastasized into his bones" and that it's "very painful and it’s very debilitating.” His 83-year-old father was the oldest man to serve as U.S. president and his age was a concern for much of his four years in office.

Health officials serving under President Donald Trump want to make it easier for men to get a prescription for testosterone. It's the latest shift in an ongoing debate over the benefits and risks of boosting the hormone. Defense Secretary Pete Hegseth announced this week that the military would begin screening for low testosterone and offering the hormone to troops. That approach follows the advice of some men's health influencers, who promote testosterone as an all-purpose formula for strength and vitality. Experts disagree with that assessment. But they do say new evidence supports testosterone's benefits for sexual problems like erectile dysfunction and low libido.
