Squamous Cell Carcinomas (SCC) are the second most common skin cancer in Australia. Ultraviolet radiation from the sun is a common risk factor for developing SCC's. Other risk factors include a suppressed immune system, sites of previous injury such as a burn or radiation, or a viral infection such as the Human Papilloma Virus (HPV).

 

Squamous Cell Carcinomas may arise from a pre-existing Actinic Keratosis (sunspot). An SCC that is confined to the top layer of the skin (epidermis) is called Bowen’s disease. When the tumour cells break away from the epidermis, then it is known as an invasive SCC. If left untreated, squamous cell carcinomas can potentially spread to the lymph nodes and internal organs. Sometimes a diagnosis of an SCC may require a biopsy. Squamous Cell  Carcinomas may be treated with topical creams, Standard Surgical excision or Mohs Micrographic Surgery.
