Know Before It Grows
Experienced Oral Biopsy Surgeon in Fresno, CA
Noticing something unusual in your mouth, whether it is a sore that will not heal, a lump, a discolored patch, or an area of unexplained tenderness, is never something to ignore. An oral biopsy allows Dr. Nassiri to examine the tissue or bone in question at a cellular level, providing a definitive diagnosis that guides everything that comes next.
An oral biopsy is not a cause for alarm on its own. Many biopsies come back benign, and the procedure itself is straightforward and minimally invasive. What matters most is that concerning findings are evaluated promptly rather than monitored and dismissed, because early detection makes an enormous difference in outcomes.
At Valley Oak Oral Surgery, Dr. Justin Nassiri approaches every biopsy case with the seriousness and sensitivity it deserves. Fresno patients trust us to handle these moments with honesty, compassion, and the clinical precision needed to get accurate results as efficiently as possible.

First Step
The first step toward an oral biopsy in Fresno is scheduling a consultation with Dr. Justin Nassiri at Valley Oak Oral Surgery. During your visit, Dr. Nassiri will examine the area of concern, review your medical and dental history, and determine whether a biopsy is the appropriate next step. If it is, he will explain exactly what the procedure involves and what you can expect before, during, and after.
If you have been referred by your dentist or another provider, Dr. Nassiri will review the referral notes and any existing imaging before your appointment to make the most of your time together. Every patient who comes in with a concern is given the time and attention they deserve.
Once a biopsy is confirmed as the right course of action, our team will walk you through scheduling, preparation instructions, and what to expect on the day of the procedure. At Valley Oak Oral Surgery, no patient leaves without a clear plan and the confidence that they are in the right hands.
What Is an Oral Biopsy?
An oral biopsy is a diagnostic procedure in which a small sample of tissue or bone is removed from the mouth and sent to a pathology lab for analysis. The results tell Dr. Nassiri whether the sampled cells are normal, precancerous, or malignant, and provide the information needed to determine the appropriate course of treatment. It is the most reliable way to evaluate suspicious findings in the mouth that cannot be diagnosed through visual examination alone.
Oral biopsies are performed for a wide range of reasons. Common indications include persistent mouth sores or ulcers that do not heal within two weeks, white or red patches on the gums, tongue, or inner cheeks, unexplained lumps or thickening in the soft tissue, areas of numbness or tenderness without a clear cause, and unusual changes in the bone visible on dental imaging. Any finding that raises concern during a routine exam or that a patient notices on their own warrants evaluation.
There are several types of oral biopsies and the approach Dr. Nassiri uses depends on the size, location, and nature of the area being evaluated. Some biopsies involve removing a small portion of the affected tissue for analysis, while others involve removing the entire lesion at once. Bone biopsies address abnormalities identified in the jaw through imaging and require a different technique than soft tissue procedures.
The procedure is performed under local anesthesia and is generally well tolerated. Most patients experience minimal discomfort during and after the biopsy, and the sample is sent to a pathology lab where results are typically returned within one to two weeks. Dr. Nassiri reviews the findings with every patient personally and discusses the next steps based on what the results reveal.

Oral Biopsy Process
Knowing what to expect from an oral biopsy can go a long way toward easing the anxiety that often comes with the unknown. At Valley Oak Oral Surgery, Dr. Nassiri walks every patient through each step clearly and ensures the experience is as comfortable and efficient as possible.

1.)
Consultation & Evaluation
Dr. Nassiri examines the area of concern and reviews any relevant imaging or referral documentation. He determines the most appropriate type of biopsy based on the location, size, and appearance of the finding and explains the plan to the patient before moving forward.
2.)
Anesthesia & Comfort
Local anesthesia is administered to numb the area completely before the procedure begins. For patients with significant anxiety, sedation options are available to ensure a calm and comfortable experience from start to finish.
3.)
Tissue or Bone Sample Collection
Dr. Nassiri carefully removes the tissue or bone sample using precise surgical technique. Depending on the nature of the finding, he may remove a portion of the area or the entire lesion in a single procedure.
4.)
Lab Submission
The sample is prepared and submitted to a certified pathology lab for analysis. Results are typically returned within one to two weeks, during which time Dr. Nassiri's team remains available to answer any questions.
5.)
Results & Next Steps
Dr. Nassiri reviews the pathology report with every patient personally. If the results require further treatment, he will outline the options clearly and work with you and any other involved providers to determine the best path forward.
Types of Oral Biopsy
Incisional Biopsy
An incisional biopsy involves removing a small portion of the suspicious tissue for analysis while leaving the remainder in place. This approach is typically used when the lesion is large or when Dr. Nassiri wants to confirm the diagnosis before determining the full scope of treatment.
Excisional Biopsy
An excisional biopsy removes the entire lesion in a single procedure. This technique is used when the area of concern is small enough to be fully excised and serves as both a diagnostic and potentially therapeutic procedure in one step.
Punch Biopsy
A punch biopsy uses a small circular instrument to remove a precise core of tissue from the affected area. It is a minimally invasive option well suited for evaluating surface lesions on the gums, tongue, or inner cheeks.
Cytology
Cytology involves the collection and examination of cells from the surface of oral tissues to detect precancerous or cancerous changes without the need for a surgical incision. It is a minimally invasive screening option that can be used as an initial step when a concerning area is identified, with the collected cells sent directly to a pathology lab for evaluation.

Bone Biopsy
When an abnormality is identified in the jawbone through dental imaging, a bone biopsy may be necessary to determine its nature. Dr. Nassiri accesses the area through the overlying soft tissue to collect the bone sample needed for pathological analysis.

Healing Guidelines
The biopsy itself is just one part of the process. How you care for the surgical site in the days that follow plays an important role in how comfortably and quickly you heal. Following Dr. Nassiri's aftercare instructions helps protect the area and keeps the healing process on track while you wait for your results.
Some mild soreness, swelling, and sensitivity at the biopsy site are normal and expected in the first few days. Dr. Nassiri and his team will provide clear instructions on managing discomfort, what foods to avoid, how to keep the area clean, and what signs to watch for that may warrant a follow-up call.
Waiting for biopsy results can be an anxious time, and Dr. Nassiri's team is available to answer questions and provide support throughout the process. Once results are in, Dr. Nassiri will contact you personally to go over the findings and discuss what comes next.

Who Are the Best Candidates for an Oral Biopsy?
An oral biopsy is recommended for anyone with a finding in the mouth that cannot be diagnosed through visual examination alone. It is not reserved for patients who are already showing signs of serious illness. In fact, the most important time to pursue a biopsy is before a concerning finding has a chance to progress.
Dr. Nassiri evaluates every patient individually and only recommends a biopsy when it is clinically warranted. His goal is always to get you the information you need as efficiently as possible so that the appropriate next steps can begin without delay.
