On May 19, according to US media reports, on Sunday local time, former US President Joe Biden's private office issued a statement saying that Biden has been diagnosed with aggressive prostate cancer and that the cancer cells have spread to the bones. "Last week, Biden was diagnosed with prostate nodules after experiencing increasing urinary symptoms. On Friday, he was diagnosed with prostate cancer with a Gleason score of 9 (grade 5) and accompanied by bone metastases." The statement also said, "Although this is a more aggressive disease, this cancer appears to be hormone-sensitive and therefore can be managed effectively." Biden and his family are "reviewing treatment options with his doctor," the statement said.
