Navigating Prostate Biopsy: Understanding When It's Necessary

Ari Horesh

Prostate cancer, a prevalent concern among men, especially as they age, involves complex decision-making regarding diagnosis and treatment. Dr. Peter Attia and Ted Schaeffer dive deep into the intricacies of prostate biopsies in their enlightening discussion, "Who should get a prostate biopsy?" This article unpacks their conversation, offering crucial insights into when a biopsy is necessary and how to interpret its results.

Who Needs a Prostate Biopsy?

Understanding PSA Density and MRI Results

  • Abnormal Blood Testing: The journey to a prostate biopsy often starts with abnormal blood tests, particularly elevated PSA (Prostate-Specific Antigen) levels.
  • The Role of MRI: Following abnormal blood tests, an MRI is typically the next step. However, exceptions exist, such as men with bilateral hip replacements, where MRI becomes ineffective.

Evaluating MRI and PSA Density

  • MRI Findings: Lesions rated as 3, 4, or 5 on the MRI require a biopsy, independent of PSA density.
  • Age Considerations in PSA Density: For men under 60, a PSA density greater than 0.1 or 0.12 indicates a biopsy. Over 65, the threshold is slightly higher at 0.15.

Interpreting Biopsy Results

The Gleason Score: Decoding Cancer Aggressiveness

  • Understanding Gleason Score: Pathologists use the Gleason score to describe the pattern and aggressiveness of prostate cancer.
  • Gleason Patterns: Today's patterns are 3, 4, and 5. The sum of the most common patterns found in the biopsy gives the Gleason score.

Biopsy Procedure and Technique

  • Systematic Approach: A standard biopsy involves 12 systematic samples plus targeted sampling of lesions.
  • Skill in Biopsy: The procedure's success significantly depends on the skill of both the urologist performing the biopsy and the pathologist interpreting the results.

Deciding on Treatment

When to Treat vs. Monitor

  • Low Aggressiveness (Gleason 6): Gleason 6 cancers are usually considered for monitoring rather than immediate treatment.
  • Impact of Cancer Volume and Distribution: Treatment decisions depend on the cancer's volume and the distribution of different Gleason patterns.

Evolving Approach to Prostate Cancer Management

  • From Immediate Treatment to Surveillance: Historically, any detection of cancer led to immediate treatment. However, understanding of prostate cancer has evolved, leading to more surveillance and less invasive approaches for low-aggressive cancers.

Patient-Centered Decision Making

  • Balancing Risks and Benefits: Decisions regarding treatment or monitoring must consider potential surgical and radiation risks versus the cancer's aggressiveness and potential for spread.


The discussion between Dr. Attia and Ted Schaeffer sheds light on the nuanced decisions surrounding prostate biopsies. From determining the need for a biopsy to interpreting results and deciding on treatment, the approach to prostate cancer requires a careful balance of medical insight and patient-specific considerations. As research and understanding of prostate cancer continue to evolve, so will strategies for its diagnosis and management.

"In medicine, there's never always and there's never never." - This statement aptly sums up the complexity and individualized nature of decisions in prostate cancer diagnosis and treatment.

The insight offered by Dr. Attia and Schaeffer not only informs but also empowers patients and healthcare providers in making informed choices about prostate cancer management. As we continue to advance in medical science, the focus remains steadfast on providing patient-centered care that is both effective and empathetic.
