Question: What Are the Symptoms of Squamous Cell Skin Cancer?
Answer: Squamous cell skin cancer (SCC) most often appears as a crusted or scaly area of skin with a red inflamed base that resembles a growing tumor, a non-healing ulcer, or a crusted-over patch of skin (more pictures of squamous cell skin cancer are available). While most commonly found on sun-exposed areas of the body (especially on the face, ear, neck, lips, and backs of the hands), it can develop anywhere, including the inside of the mouth and the genitalia. It can also begin within scars or skin ulcers on other places on the body. SCC may also arise from actinic keratoses, which are dry, scaly skin lesions that may be skin-colored, reddish-brown or yellowish-black.
