Former President Joe Biden used his first public remarks since his office announced his diagnosis with an aggressive form of prostate cancer to honor his late son, Beau, and other military veterans. The Democrat spoke in a loud steady voice as he addressed an annual gathering in honor of Memorial Day at Veterans Memorial Park in New Castle, Delaware, not far from his home in Wilmington. Biden called upon the group to remember the sacrifices of those lost in battle, whose echoes he said can still be heard urging citizens to “stay true to what America stands for.” “They’re not asking us to do their jobs,” he said. “They’re asking us to do our job, to protect our nation, in our time, now, to defend democracy, be part of something bigger than ourselves.” Biden’s office announced two weeks ago that he has been diagnosed with aggressive prostate cancer and is reviewing treatment options with his doctors. Biden, 82, was having increasing urinary symptoms and was seen by doctors who found a prostate nodule. He was then diagnosed with prostate cancer and the cancer cells have spread to the bone, his office said in a statement.
