Spot Check: When to Biopsy a Mole
Published: May 28, 2024
Not all moles need a biopsy, but certain signs could indicate a necessity. Discover when to take action and why a biopsy is crucial.
Signs That Demand Attention
Moles with features like asymmetry, irregular borders, or multiple colors might need a closer look. A sudden change in size or appearance can also be a red flag. These are essential indicators for when a biopsy might be necessary.
Special Cases: Nevi in Unusual Locations
Moles on the palms, soles, or nail matrix can be more concerning and may warrant a biopsy. These locations are less common for benign moles but can be sites for melanoma. Monitoring changes in these areas is critical.
Technique Matters: How Biopsies Are Done
When a biopsy is performed, ensuring the entire mole is examined is vital. This allows for accurate diagnosis and ensures that any suspicious features are thoroughly evaluated. Providing detailed information to the pathologist can aid in the diagnosis.
