I've had 3 removed over the years. (Thanks, Sun!) A lot depends on how early you catch it, and that's why it's important to be familiar with your skin. If something is suspicious, of course have it checked out. The treatment/removal varies. If it's on the face, you should definitely investigate what's called MOHS surgery. Your dermatologist will know what that is. It takes a specialized doctor to do this type of surgery and it's impressive. Good luck.
Currently, surgical excision is the most common form of treatment for skin cancers. The goal of reconstructive surgery is restoration of normal appearance and function. The choice of technique in reconstruction is dictated by the size and location of the defect. Excision and reconstruction of facial skin cancers is generally more challenging due to presence of highly visible and functional anatomic structures in the face.
