What is it?

Excisions remove entire lesions, while biopsies obtain samples for analysis, aiding diagnosis and treatment planning in dermatology. Excisions are used to remove skin lesions and get rid of a potentially harmful or unwanted lesion on your body. Skin lesions that could present a risk include squamous cell carcinoma, basal cell carcinoma or malignant melanoma. Additionally, excisions are performed to get rid of benign (non-cancerous) lesions.

A biopsy is when tissue is removed for laboratory analysis. This diagnostic procedure involves taking a tissue sample for microscopic examination to identify skin abnormalities. Biopsies help diagnose conditions like moles, lesions and rashes. Our Skin Care Center’s board-certified dermatologists commit to communicating biopsy results within one to two weeks.   

Types of growths that may need a biopsy for a diagnosis include:

• Moles
• Warts
• Cysts
• Actinic keratosis
• Skin cancers
• Skin infections
• Skin tags
• Bullous pemphigoid
• Inflammatory skin conditions like dermatitis and psoriasis
