What Is a Prostate Biopsy?

A prostate biopsy is a diagnostic procedure in which a urologist removes small tissue samples from the prostate. A pathologist then examines the samples under a microscope.

A biopsy can help determine:

• Whether prostate cancer is present
• Which areas contain cancer
• How abnormal the cells appear
• The cancer’s Gleason score and Grade Group
• How much of each sample is involved
• Whether additional treatment planning is needed

A biopsy is currently required to confirm a prostate cancer diagnosis. RadiologyInfo: Prostate Biopsy

Why Is a Prostate Biopsy Recommended?

A urologist may recommend biopsy because of:

• Persistently elevated PSA
• Rising PSA over time
• Abnormal digital rectal examination
• Suspicious prostate MRI lesion
• Increased PSA density
• Concerning biomarker results
• Strong family history
• Genetic cancer risks
• Previous atypical biopsy findings
• Continued suspicion after a negative biopsy
• Changes during active surveillance

An elevated PSA alone does not prove that cancer is present. Infection, inflammation, prostate enlargement, urinary retention, and recent procedures can also affect PSA.

Tests Before Prostate Biopsy

The evaluation may include:

• Repeat PSA testing
• Free-to-total PSA
• Digital rectal examination
• Urinalysis and urine culture
• Prostate ultrasound
• Multiparametric MRI
• PSA density calculation
• Additional prostate biomarkers
• Blood count and clotting tests

When infection or temporary prostate irritation is suspected, the doctor may recommend treating or monitoring that condition before proceeding.

Types of Prostate Biopsy

Transperineal Prostate Biopsy

During a transperineal biopsy, the needle enters through the perineal skin between the scrotum and anus.

Ultrasound placed in the rectum may still be used to display the prostate and guide sampling.

Potential advantages include:

• Reduced exposure to rectal bacteria
• Lower infection risk
• Access to anterior prostate areas
• Suitability for systematic and MRI-targeted sampling

Local anesthesia, sedation, or general anesthesia may be used depending on the technique and facility.

Transrectal Prostate Biopsy

During a transrectal biopsy, tissue samples are collected through the rectal wall under ultrasound guidance.

Potential advantages include:

• Short procedure time
• Familiar outpatient technique
• Local anesthesia in many cases
• Broad availability

Because the needle passes through the rectum, antibiotic preparation and infection precautions are especially important.

Transperineal vs. Transrectal Biopsy

The recommended approach may depend on:

• Infection risk
• Prostate size
• Lesion location
• Previous biopsy history
• MRI findings
• Anesthesia options
• Blood-thinning medication
• Clinic equipment
• Surgeon experience
• Patient preference

Both methods can obtain clinically useful tissue samples when performed appropriately.

Systematic Prostate Biopsy

A systematic biopsy collects tissue from several predefined areas throughout the prostate.

It may help detect cancer that is:

• Not visible on MRI
• Located outside a targeted lesion
• Distributed across multiple prostate areas

The number of samples depends on prostate size, biopsy method, and clinical plan.

MRI-Targeted Prostate Biopsy

MRI-targeted biopsy focuses on lesions previously identified through multiparametric MRI.

Targeting methods may include:

• Visual or cognitive targeting
• MRI-ultrasound fusion biopsy
• Direct in-bore MRI-guided biopsy

MRI-ultrasound fusion combines previously acquired MRI images with real-time ultrasound guidance. RadiologyInfo: MRI-Guided Prostate Biopsy

Targeted Plus Systematic Biopsy

A urologist may combine MRI-targeted samples with systematic sampling.

This approach may help:

• Sample the suspicious MRI lesion accurately
• Evaluate the remainder of the prostate
• Detect clinically important cancer outside the target
• Improve diagnostic confidence

The recommended sampling strategy depends on MRI findings and previous biopsy history.

Can MRI Replace Prostate Biopsy?

No. MRI can identify suspicious areas and help determine whether biopsy is appropriate, but it cannot confirm cancer by itself.

A normal or low-suspicion MRI can reduce concern in some patients, but clinically significant cancer may occasionally be present despite a negative MRI.

The decision should consider PSA, prostate size, family history, examination findings, biomarkers, and overall risk.

How to Prepare for Prostate Biopsy

Preparation may include:

• Urinalysis and urine culture
• Blood and clotting tests
• Antibiotics when prescribed
• Enema for selected transrectal procedures
• Fasting when sedation or anesthesia is planned
• Medication adjustment
• Transportation arrangements
• Consent and risk review

Follow the clinic’s specific instructions rather than using a general preparation plan.

Blood-Thinning Medication

Patients must tell the urologist about:

• Aspirin
• Warfarin
• Clopidogrel
• Apixaban
• Rivaroxaban
• Dabigatran
• Anti-inflammatory medication
• Herbal supplements affecting bleeding

Do not stop blood-thinning medication without coordinated instructions from the prescribing physician and biopsy team.

Antibiotics Before Biopsy

Antibiotics may be prescribed to reduce infection risk, particularly for transrectal biopsy.

The plan may depend on:

• Biopsy route
• Local bacterial resistance
• Previous infection
• Recent antibiotic use
• Urine culture
• Medication allergies

Patients should take antibiotics exactly as instructed.

Anesthesia and Pain Control

Pain control may involve:

• Local anesthetic injection
• Periprostatic nerve block
• Sedation
• General anesthesia
• A combination of methods

The choice depends on the biopsy route, number of samples, facility protocol, and patient health.

What Happens During a Transperineal Biopsy?

The typical process may include:

1. The patient receives local anesthesia, sedation, or general anesthesia.
2. An ultrasound probe displays the prostate.
3. A guide is positioned against the perineal skin.
4. Biopsy needles collect systematic or targeted samples.
5. Tissue samples are labeled and sent for pathology.
6. The patient is monitored during recovery.

The perineal puncture sites are generally small and may not require stitches.

What Happens During a Transrectal Biopsy?

The patient commonly lies on one side with the knees bent.

The doctor then:

1. Inserts a covered ultrasound probe into the rectum.
2. Measures and examines the prostate.
3. Applies local anesthesia.
4. Guides a biopsy needle through the rectal wall.
5. Collects tissue samples.
6. Sends the samples for pathological examination.

Patients may hear a clicking sound and feel brief pressure or stinging as samples are obtained.

How Long Does the Procedure Take?

The biopsy itself may be relatively brief, but the full visit can take longer because of:

• Pre-procedure preparation
• Anesthesia
• MRI-ultrasound image fusion
• Recovery monitoring
• Urination assessment
• Medication and discharge instructions

Patients receiving sedation or general anesthesia may need someone to accompany them.

Recovery After Prostate Biopsy

Temporary effects may include:

• Blood in the urine
• Blood in the semen
• Mild rectal bleeding after transrectal biopsy
• Perineal bruising after transperineal biopsy
• Urinary burning
• Pelvic discomfort
• Temporary urinary frequency
• Fatigue after anesthesia

Blood in the semen may remain visible longer than blood in the urine and can change from red to brown as it resolves.

Activity After Prostate Biopsy

The clinic may advise patients to temporarily avoid:

• Heavy lifting
• Strenuous exercise
• Cycling
• Sexual activity
• Long-distance travel immediately after the procedure
• Alcohol when using certain medications
• Swimming or bathing until instructed

Follow the medical team’s specific recovery plan.

Possible Risks and Complications

Potential complications include:

• Urinary infection
• Fever or sepsis
• Urinary retention
• Significant bleeding
• Blood clots in the urine
• Rectal bleeding
• Perineal hematoma
• Pain
• Temporary erectile or ejaculation changes
• Allergic reaction to medication
• Anesthesia complications

The risk profile varies between transperineal and transrectal approaches.

When Should You Seek Emergency Care?

Seek urgent medical attention for:

• Fever or shaking chills
• Inability to urinate
• Heavy or persistent bleeding
• Large blood clots
• Severe pelvic or abdominal pain
• Dizziness or fainting
• Confusion or severe weakness
• Persistent vomiting
• Rapidly worsening symptoms

Fever after a prostate biopsy may indicate a serious infection and should not be monitored at home without medical advice.

Understanding Prostate Biopsy Results

The pathology report may describe:

• Benign prostate tissue
• Inflammation
• Atypical cells
• Precancerous or high-risk changes
• Prostate cancer
• Gleason pattern
• Gleason score
• Grade Group
• Number of positive samples
• Percentage or length of cancer in each sample
• Additional pathological features

The urologist should interpret the entire report rather than focusing on one number.

Gleason Score and Grade Group

When prostate cancer is found, the pathologist evaluates the appearance and growth pattern of the cells.

The report may provide:

• A primary Gleason pattern
• A secondary Gleason pattern
• A combined Gleason score
• A Grade Group from 1 to 5

A higher Grade Group generally indicates more aggressive-looking cancer cells.

Treatment planning also considers PSA, MRI, clinical stage, cancer volume, age, health, and patient preferences.

What If the Biopsy Is Negative?

A negative biopsy means that cancer was not identified in the samples collected. It does not always guarantee that no cancer exists elsewhere in the prostate.

Follow-up may include:

• Repeat PSA
• Digital rectal examination
• Prostate MRI
• Biomarker testing
• Continued observation
• Repeat targeted or systematic biopsy

The plan depends on the reason the original biopsy was performed and the patient’s ongoing risk.

What If Cancer Is Found?

Additional evaluation may include:

• Review of Gleason score and Grade Group
• Prostate MRI
• CT, bone imaging, or specialized PET imaging when indicated
• Genomic testing in selected cases
• Discussion of active surveillance
• Surgery consultation
• Radiation oncology consultation
• Hormone treatment planning
• Focal treatment evaluation

Not every prostate cancer requires immediate treatment. Some lower-risk cancers may be monitored through active surveillance.

Biopsy During Active Surveillance

Patients with low-risk prostate cancer may undergo repeat PSA tests, MRI, examinations, and additional biopsies.

A repeat biopsy may help determine whether:

• The cancer remains low risk
• The Grade Group has changed
• Cancer volume has increased
• Active treatment should be considered

Frequently Asked Questions

Does an elevated PSA mean I need a biopsy?

Not always. The doctor may repeat PSA or recommend urine testing, MRI, biomarkers, and risk assessment before deciding.

Which is better: transperineal or transrectal biopsy?

Both can collect diagnostic tissue. Transperineal biopsy generally reduces exposure to rectal bacteria and may better access certain prostate areas.

Is prostate biopsy painful?

Patients may feel pressure or brief discomfort, but local anesthesia, sedation, or general anesthesia can be used depending on the method.

How long will blood remain in the semen?

Blood discoloration may remain visible for several weeks in some patients. Contact the clinic if bleeding is heavy, worsening, or associated with severe symptoms.

Can a negative biopsy miss cancer?

Yes. A biopsy samples selected areas rather than the entire prostate. Continued PSA monitoring, MRI, or repeat biopsy may be recommended.

Can international patients receive MRI-targeted biopsy in Busan?

Yes. Selected centers offer MRI-ultrasound fusion and targeted prostate biopsy, although availability and preparation requirements vary.
