Squamous Cell Carcinoma (SCC) is the second most common skin cancer in Australia. Ultraviolet radiation from the sun is a common risk factor for developing SCCs. Other risk factors include: a suppressed immune system; sites of previous injury (such as a burn or radiation); or a viral infection.

 

SCCs can arise from a pre-existing actinic keratosis (sunspot). An SCC that is confined to the epidermis (most superficial layer of the skin) is called Bowen’s disease. When the tumour cells break away from the epidermis, it is known as an invasive SCC. Diagnosis may sometimes require a biopsy. If left untreated, SCCs can potentially spread to the lymph nodes and internal organs. SCCs may be treated with topical creams, standard surgical excision or Mohs Micrographic Surgery.
