Performed under local anaesthetic C&C is a simple technique used to remove benign warts, seborrheic keratosis, actinic keratosis, squamous cell carcinoma insitu (Bowens disease) and low risk basal cell carcinomas. Depending on how it is performed C&C wounds are often slow to heal over several weeks, painful at first eventually leaving a hypopigmented scar.
Excision biopsy is performed under local anaesthetic typically to remove concerning skin lesions that are either skin cancer or possible skin cancer. This technique aims to remove the entire lesion to allow accurate diagnosis and also definitive treatment. Excision biopsy is the preferred treatment for most basal cell carcinomas off the face (for facial lesions consider Mohs micrographic surgery), squamous cell carcinomas, suspicious or changing moles and other types of skin cancer.
