Biden’s Prostate Cancer: What We Know

1. The Announcement

• Former President Biden’s Health Update

On Sunday, May 18, 2025, a statement from former President Joe Biden’s personal office provided an update on his health. It was revealed that he had received a significant medical diagnosis just two days prior.

• Diagnosis Revealed: Aggressive Prostate Cancer

The core of the announcement was the diagnosis of an aggressive form of prostate cancer. This news was shared following a medical evaluation prompted by concerning symptoms.

• How the Diagnosis Was Made

Due to worsening urinary problems, former President Biden was examined by physicians last week. A little lump on his prostate was found during this examination.

Consequently, further tests were deemed necessary, and on Friday, the diagnosis of prostate cancer was confirmed.

2. Understanding Prostate Cancer

• What is the Prostate Gland?

A little gland that is a component of the male reproductive system is called the prostate. It is located below the bladder and surrounds the urethra. Fluid produced by the prostate contributes to semen.

• Prostate Cancer Basics: Prevalence and Risk Factors

Prostate cancer is a common malignancy affecting men. It is considered the second most common cancer in males, after skin cancer.

Although the precise reasons remain unclear, a number of risk factors have been found. Age is a primary risk factor; the likelihood of developing prostate cancer increases significantly after age 50.

• Prostate Cancer in the U.S.: Key Statistics, Including Age and Racial Disparities

In the United States, prostate cancer statistics highlight its impact. Approximately 13 out of every 100 men will be diagnosed with the disease in their lifetime.

Age plays a crucial role, with about 6 in 10 prostate cancers being diagnosed in men aged 65 or older. Approximately 67 is the usual age at diagnosis.

Furthermore, significant racial disparities are observed. African American men are more than twice as likely to die from prostate cancer and have a greater incidence rate of the illness than white men.

3. Breaking Down the Specifics of the Diagnosis

• Understanding “Aggressive” Prostate Cancer

The term “aggressive” indicates that the cancer is likely to grow and spread quickly. This contrasts with more indolent forms of prostate cancer that may grow slowly and not require immediate treatment.

• Decoding the Gleason Score: What Does a 9 Mean?

Prostate cancer cells are graded for aggressiveness using the Gleason scoring system, which ranges from 6 to 10. Tissue samples from a biopsy are examined, and the two most common patterns of cancer cells are assigned grades (from 3 to 5).

These grades are added together to get the Gleason score. A score of 9, as in Mr. Biden’s case, is among the highest scores and signifies a high-grade, poorly differentiated cancer with a greater potential for rapid growth and spread.

• Metastasis: When Cancer Spreads

Metastasis occurs when cancer cells break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors in other parts of the body. This indicates that the cancer is no longer confined to the prostate.

• The Significance of Bone Metastasis

According to Biden’s diagnosis, the disease has progressed to his bones. The bones are a common site for prostate cancer to metastasize. The presence of bone metastasis confirms that the cancer is at an advanced stage (typically Stage IV).

• Hormone-Sensitive Cancer: A Crucial Detail

Importantly, the announcement stated that the cancer appears to be hormone-sensitive. Accordingly, male hormones, particularly testosterone, are responsible for the proliferation of the cancer cells.

Consequently, treatments that reduce or block these hormones can be effective in controlling the cancer’s growth, at least initially.

4. Implications and Prognosis

• How Serious Is This Stage of Prostate Cancer?

Metastatic prostate cancer, or prostate cancer that has spread to the bone, is a dangerous illness. It is considered an advanced-stage disease and is generally not curable.

• Prognosis for Metastatic Hormone-Sensitive Prostate Cancer

While not curable, metastatic hormone-sensitive prostate cancer is treatable. Outcomes have improved significantly in recent decades due to advances in therapy.

Prognosis can vary depending on individual factors, but with treatment, patients can often live for several years. For distant-stage prostate cancer, the 5-year relative survival rate is approximately 34%, although this is an average across all distant cases and can be influenced by factors like hormone sensitivity and response to treatment.

• Living with Advanced Prostate Cancer

Living with advanced prostate cancer involves ongoing medical management. Treatment is aimed at controlling the disease, alleviating symptoms (such as bone pain), and maintaining the best possible quality of life.

5. Treatment and Management

• Possible Treatment Options Being Reviewed

Mr. Biden’s doctors are discussing treatment options with him and his family. Based on the characteristics of his cancer (metastatic, Gleason 9, hormone-sensitive), systemic therapies are typically recommended.

• The Role of Hormone Therapy

Hormone therapy is a cornerstone of treatment for hormone-sensitive metastatic prostate cancer. These treatments work by lowering the levels of male hormones or blocking their action on cancer cells, thus slowing the cancer’s growth.

• Managing Metastatic Prostate Cancer

Management of metastatic prostate cancer often involves a combination of therapies. While hormone therapy is usually the initial approach for hormone-sensitive disease, other treatments like chemotherapy, targeted therapy, or immunotherapy may be used, particularly if the cancer becomes resistant to hormone therapy over time.

6. Broader Context

• Prostate Cancer: Recognizing Symptoms and the Importance of Detection

Symptoms of prostate cancer, particularly in early stages, may be subtle or absent. However, urinary symptoms, such as difficulty urinating or increased frequency, can occur, especially as the prostate enlarges or if the cancer affects the urethra.

The diagnosis in Mr. Biden’s case was prompted by such symptoms. Early detection, often through screening methods like PSA blood tests and digital rectal exams, is important, although the decision to screen is a personal one based on individual risk factors and discussion with a healthcare provider.

• Biden’s Personal History with Cancer and the Cancer Moonshot

This is not Mr. Biden’s first experience with cancer in his family; his son Beau died of brain cancer in 2015. This personal tragedy significantly influenced his dedication to cancer research.

As vice president, he spearheaded the original Cancer Moonshot initiative, and he reignited this effort during his presidency with the ambitious goal of dramatically reducing cancer deaths and improving the lives of patients and their families.

• Responses to the Diagnosis

Following the announcement, messages of support and well wishes for Mr. Biden and his family were shared by political figures from both the Democratic and Republican parties, including former President Donald Trump and former Vice President Kamala Harris.

Conclusion

Former President Joe Biden’s diagnosis of aggressive, metastatic, hormone-sensitive prostate cancer, while serious, is a condition for which treatments are available. The specifics of his diagnosis, including the high Gleason score and spread to bone, highlight the advanced nature of the disease.

However, the indication that it is hormone-sensitive offers a path for effective management through targeted therapies. This announcement brings renewed attention to the prevalence of prostate cancer, the importance of understanding its risk factors and symptoms, and the ongoing efforts in cancer research, a cause to which Mr. Biden has long been committed. 

As he and his family consider treatment options, they do so with the support of many and in the context of significant advancements made in the fight against this disease.
