A biopsy is typically recommended when imaging or a physical examination identifies a change that requires further clarification. It is a diagnostic step, not a diagnosis in itself.
Depending on the situation, the biopsy may be performed using a core needle or through a small excisional procedure. Both approaches are designed to safely obtain a sample of tissue for detailed analysis.
The procedure is carefully planned to ensure comfort and precision, and it is commonly performed with minimal disruption to daily activities.

No. A biopsy is a diagnostic step used to clarify a finding, and many biopsies show benign (non-cancerous) results. It is done to get a definitive answer rather than to confirm a diagnosis.
A core needle biopsy uses a needle to take a small tissue sample, while an excisional biopsy removes a small area of tissue surgically. The choice depends on the location and nature of the finding.
The area is numbed and the procedure is planned for comfort. Most patients describe pressure rather than pain, with mild tenderness at the site afterward.
Tissue is sent for detailed analysis, and results typically take a few days. They will be reviewed with you clearly, along with any recommended next steps.
It depends on the procedure. Minor procedures are usually done with local anesthesia, sometimes with light sedation. Laparoscopic and larger operations are usually done under general anesthesia. Dr. Arsenous will explain the plan for your specific case at your consultation.
Dr. Arsenous reviews your symptoms, medical history and any imaging, examines you, and explains whether surgery is recommended, what the options are, and what recovery involves. Bring your insurance card, a photo ID, a list of your medications and any previous imaging or reports.
