• Lifestyle modifications: Sun protection, gentle skincare, stress management

5. What are the different types of skin biopsies and when are they used?

• Punch biopsy: A circular sample of skin is removed using a punch tool. Used for evaluating skin lesions, suspected malignancies, and inflammatory conditions.
• Shave biopsy: A thin layer of skin is shaved off using a scalpel. Used for superficial lesions or when a larger sample is not necessary.
• Excisional biopsy: The entire lesion is surgically removed. Used for suspected malignancies, deep lesions, or when complete removal is desired.
