What is a Biopsy?
A biopsy is a diagnostic procedure in which a small sample of skin tissue is removed and sent to a specialized laboratory for microscopic examination. This allows us to study the tissue in detail and determine the presence of abnormalities such as:
- Skin cancers (e.g., basal cell carcinoma, squamous cell carcinoma, melanoma)
- Benign growths (e.g., warts, moles)
- Inflammatory skin conditions (e.g., psoriasis, eczema, dermatitis)
- Infections (e.g., fungal, bacterial, or viral)
Types of Skin Biopsies
We use several biopsy techniques depending on the type, size, and location of the lesion:
- Shave Biopsy: Removes a thin layer of skin, often used for raised or superficial lesions.
- Punch Biopsy: Extracts a small, cylindrical section of skin, ideal for deeper analysis.
- Excisional Biopsy: Removes the entire lesion for comprehensive evaluation, typically for suspected melanomas or larger growths.
What to Expect During a Biopsy
A skin biopsy is a quick and minimally invasive procedure performed in the office. Here’s what you can anticipate:
- Preparation: The area is cleaned, and a local anesthetic is applied to ensure your comfort.
- Tissue Removal: Using sterile instruments, your dermatologist carefully removes the tissue sample.
- Wound Care: The site is treated with ointment and covered with a bandage. In some cases, sutures may be needed.
Aftercare & Results
- Healing: Most biopsy sites heal within 1-2 weeks. You may experience minor redness or discomfort, which is temporary.
- Pathology Report: The sample is sent to a dermatopathologist for analysis, and results are typically available within 7-10 days. Your dermatologist will review the findings with you and discuss any necessary next steps.
Why Biopsies Matter
A biopsy is an essential step in ensuring accurate diagnoses and effective treatment. Early detection of skin cancer or other conditions can make a significant difference in your overall health and prognosis.
