context_page_description: Squamous cell carcinomas, also known as epidermoid carcinomas, comprise a number of different types of cancer that result from squamous cells. These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts.
  Common types include:
  Squamous cell skin cancer: A type of skin cancer
  Squamous-cell carcinoma of the lung: A type of lung cancer
  Squamous cell thyroid carcinoma: A type of thyroid cancer
  Esophageal squamous cell carcinoma: A type of esophageal cancer
  Squamous-cell carcinoma of the vagina: A type of vaginal cancer
  Despite sharing the name "squamous cell carcinoma", the SCCs of different body sites can show differences in their presented symptoms, natural history, prognosis, and response to treatment.
context_section_description: When associated with the lung, it is typically a centrally located large-cell cancer (nonsmall-cell lung cancer). It often has a paraneoplastic syndrome causing ectopic production of parathyroid hormone-related protein, resulting in hypercalcemia, but paraneoplastic syndrome is more commonly associated with small-cell lung cancer. It is primarily due to smoking.
