Squamous cell carcinoma (SCC) is the second most common form of skin cancer. It’s usually found on areas of the body damaged by UV rays from the sun or tanning beds. Sun-exposed skin includes the head, neck, ears, lips, arms, legs, and hands.

Squamous cell carcinoma can usually be treated with minor surgery that can be done in a doctor’s office or hospital clinic. Depending on the size and location of the SCC, your doctor may choose to use any of the following techniques to remove it:
