WASHINGTON (AP) โ Former President Joe Biden has been diagnosed with prostate cancer, his office said May 18.
Biden was seen by doctors last week after urinary symptoms and a prostate nodule were found. He was diagnosed with prostate cancer on May 16, with the cancer cells having spread to the bone.
โWhile this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management,โ his office said. โThe President and his family are reviewing treatment options with his physicians.โ
Prostate cancers are given a score called a Gleason score that measures, on a scale of 1 to 10, how the cancerous cells look compared with normal cells. Bidenโs office said his score was 9, suggesting his cancer is among the most aggressive.
When prostate cancer spreads to other parts of the body, it often spreads to the bones. Metastasized cancer is much harder to treat than localized cancer because it can be hard for drugs to reach all the tumors and completely root out the disease.
However, when prostate cancers need hormones to grow, as in Bidenโs case, they can be susceptible to treatment that deprives the tumors of hormones.
The health of Biden, 82, was a dominant concern among voters during his time as president. After a calamitous debate performance in June while seeking reelection, Biden abandoned his bid for a second term. Then-Vice President Kamala Harris became the nominee and lost to Republican Donald Trump, who returned to the White House after a four-year hiatus.
But in recent days, Biden rejected concerns about his age despite reporting in the new book โOriginal Sinโ by Jake Tapper and Alex Thompson that aides had shielded the public from the extent of his decline while serving as president.
In February 2023, Biden had a skin lesion removed from his chest that was a basal cell carcinoma, a common form of skin cancer. And in November 2021, he had a polyp removed from his colon that was a benign, but potentially pre-cancerous lesion.
In 2022, Biden made a โcancer moonshotโ one of his administrationโs priorities with the goal of halving the cancer death rate over the next 25 years. The initiative was a continuation of his work as vice president to address a disease that had killed his older son, Beau, who died from brain cancer in 2015.
His father, when announcing the goal to halve the cancer death rate, said this could be an โAmerican moment to prove to ourselves and, quite frankly, the world that we can do really big things.โ
