Introduction
A biopsy is an essential procedure for diagnosing pancreatic cancer. It involves taking a small tissue sample from the pancreas to help confirm the diagnosis and guide treatment options. This page will walk you through each step of the process so you can feel prepared and informed.
Diagnosis
Biopsies are the gold standard for diagnosing pancreatic cancer. The most common types used for diagnosis are:
• Fine Needle Aspiration (FNA): A thin needle is used to extract a small tissue sample from the pancreas. This method is less invasive and typically involves less discomfort.
• Core Needle Biopsy: A larger needle is used to obtain a more substantial tissue sample. This method provides more detailed information, which can be crucial for planning your treatment.
Next-Generation Sequencing (NGS)
Beyond initial diagnosis, biopsies can provide tissue samples for advanced genetic analysis using next-generation sequencing (NGS).
Philip Philip, MD, PhD, FRCP, Wayne State University School of Medicine/Henry Ford Health, Detroit, MI, discusses the future of next-generation sequencing (NGS) for patients with pancreatic cancer.
NGS is a cutting-edge technology that offers comprehensive genomic profiling of cancer cells. Key aspects of NGS in pancreatic cancer include:
1. Comprehensive genetic analysis: NGS can simultaneously detect mutations in multiple genes, providing a more complete picture of the tumor’s genetic profile. This includes important genes such as KRAS, TP53, CDKN2A, and SMAD4.
2. Targeted therapy guidance: The genetic information obtained can help identify potential targeted therapies or clinical trials that may be appropriate for the patient. Up to 19.9% of pancreatic cancer cases may have targetable genetic alterations.
3. Prognostic information: Some studies suggest that the number and type of mutations detected can provide prognostic information.
4. Detection of microsatellite instability (MSI): NGS can identify MSI, which may influence treatment decisions.

1. Preparing for Your Biopsy
Step 1: Consultation and Pre-Procedure Instructions
Your doctor will explain why a biopsy is needed and what type will be performed.
You may need to fast for a few hours before the procedure. Your healthcare team will advise you if any medications, especially blood thinners, should be paused.
You’ll be asked to sign a consent form after discussing the procedure, its benefits, and any potential risks.
Step 2: Comfort and Support
• If you’re feeling nervous, let your care team know. They may offer a mild sedative to help you relax.
• It’s often helpful to bring a friend or family member with you for emotional support.
2. The Biopsy Procedure
Step 1: Local Anesthesia
• The biopsy area will be numbed using local anesthesia to minimize discomfort during the procedure.
• In some cases, a mild sedative may be given to help you stay calm.
Step 2: Guided Imaging
• The doctor will use ultrasound or CT scans to guide the needle to the precise location in the pancreas, ensuring accurate tissue collection.
Step 3: Needle Insertion
Depending on the type of biopsy, the doctor will use:
• Fine Needle Aspiration (FNA): A thin, hollow needle is inserted to extract a small sample of tissue.
• Core Needle Biopsy: A larger needle is used to obtain a bigger, more comprehensive tissue sample.
You may feel some pressure, but the local anesthesia should prevent any sharp pain.
Step 4: Sample Collection
• The tissue sample is collected quickly, often in just a few seconds per sample. Multiple samples may be taken to ensure accurate results.
Step 5: Completing the Procedure
• Once the sample is collected, the needle is removed, and pressure is applied to the biopsy site to reduce any bleeding.
• The entire procedure typically takes between 30 and 60 minutes.

3. After the Biopsy
Step 1: Immediate Aftercare
• You’ll be monitored for a short time after the procedure to check for any immediate side effects, such as mild bleeding or soreness at the biopsy site.
Step 2: Rest and Recovery
• Most patients can go home shortly after the biopsy. It’s best to take it easy and avoid strenuous activities for at least 24 hours.
• Applying a cold pack can help reduce soreness and swelling.
Step 3: Follow-Up Care
• Your doctor will provide clear instructions on what to watch for, including signs of infection like fever or increased redness.
• Reach out to your healthcare provider if you experience severe pain or unusual symptoms.
4. What to Expect Next
Step 1: Pathologist’s Analysis
• The tissue sample is sent to a lab, where a pathologist will examine it under a microscope to determine if cancer cells are present and identify the type of pancreatic cancer.
Step 2: Discussing Results with Your Doctor
• Your doctor will review the biopsy results with you, answer any questions, and discuss the next steps in your treatment plan.
Frequently Asked Questions (FAQ)
How long does a biopsy take?
Most biopsy procedures take around 30 to 60 minutes. Fine Needle Aspiration (FNA) is usually quicker because it uses a thin needle, while a Core Needle Biopsy can take a bit longer since it involves collecting a larger tissue sample. The exact time depends on factors like the location of the pancreas and whether guided imaging is needed. Keep in mind that while the procedure itself is relatively short, you’ll also need time for preparation and monitoring afterward.
Will I be awake during the biopsy?
Yes, you’ll be awake for the biopsy, but don’t worry—you won’t feel significant pain. The procedure uses local anesthesia, which numbs the area where the needle goes in. You might feel some pressure during the sample collection, but it shouldn’t be sharp or uncomfortable. In some cases, your care team might offer a mild sedative if you’re feeling anxious, but this won’t put you fully to sleep. Staying awake helps the team make sure you’re comfortable and everything is going as planned.
Can I drive myself home after the biopsy?
It’s a good idea to have someone drive you home, especially if you were given a sedative during the procedure. Even if you only had local anesthesia, having a friend or family member with you can be a big help. Sedatives can make you feel groggy for a few hours, which could affect your ability to drive safely. Plus, it’s comforting to have support and someone to listen when the care team goes over your aftercare instructions.
When will I receive my biopsy results?
You can typically expect biopsy results within 3 to 7 days. Once the sample is taken, it’s sent to a lab where a pathologist examines it under a microscope. They’ll check for cancer cells and, if found, identify the type of pancreatic cancer. Your doctor will go over the results with you as soon as they’re ready and help you understand what they mean for your next steps. If you haven’t heard back after a week, don’t hesitate to follow up with your doctor or care team.
What are the potential risks of a biopsy?
Biopsies are usually safe, but like any medical procedure, there are some risks. The most common issues are minor—things like a little bleeding, bruising, or soreness at the biopsy site. You might notice some discomfort for a day or two afterward. There’s also a small chance of infection, which is why it’s important to follow your aftercare instructions closely. Serious complications, like internal bleeding or damage to nearby organs, are very rare but can happen, especially if the pancreas is in a tricky spot. If you experience severe pain, a high fever, or anything that feels off after the biopsy, reach out to your doctor right away.
What is a liquid biopsy?
A liquid biopsy is a simple, non-invasive blood test that looks for cancer-related markers, like DNA or cells from a tumour, to help detect, monitor, or guide treatment for cancer.
Final Tips for Patients
• Bring a Support Person: Having a friend or family member with you can provide emotional support and help you remember any instructions given by your care team.
• Wear Comfortable Clothing: Choose loose-fitting clothes that won’t press on the biopsy site after the procedure.
• Ask Questions: It’s normal to feel anxious before a biopsy. Don’t hesitate to ask your doctor or nurse if you have concerns or need clarification.
