Former US President Joe Biden Diagnosed With Aggressive Prostate Cancer

19 May, 2025

Former U.S. President Joe Biden, 82, has been diagnosed with an "aggressive" form of prostate cancer which has reportedly spread to his bones, his office announced Sunday. The diagnosis followed urinary symptoms and the discovery of a prostate nodule. Biden is currently reviewing treatment options with his medical team, facing a significant personal health challenge after his presidency.

Unpacked:

What does it mean that Biden's prostate cancer has a Gleason score of 9?

A Gleason score of 9 indicates a very aggressive and high-grade prostate cancer. This score suggests the cancer cells are poorly differentiated, grow quickly, and are more likely to spread beyond the prostate, which aligns with the report that Biden’s cancer has metastasized to his bones.

What are the typical treatment options for advanced, aggressive prostate cancer like Biden's?

Typical treatment options include hormone therapy (to reduce testosterone), chemotherapy, radiation therapy, and sometimes surgery. Since Biden’s cancer is hormone-sensitive, hormone therapy is likely to play a major role. The goal is to manage and slow the disease, as advanced metastatic prostate cancer is generally not curable but can often be controlled.

How common is prostate cancer and what are the main risk factors?

Prostate cancer is the second most common cancer in men after skin cancer. Major risk factors include age (risk increases with age), family history, and certain genetic factors. According to the CDC, about 13 out of 100 men will be diagnosed with prostate cancer in their lifetime, with risk rising significantly after age 65.

What is the general prognosis for someone Biden's age with metastatic prostate cancer?

For someone in their 80s with metastatic prostate cancer, the disease is generally considered incurable, but it is often treatable and can be managed to improve quality of life. Many patients tolerate standard treatments well, but overall survival varies, and the focus typically shifts to managing symptoms and maintaining comfort.
