Screening for squamous cell carcinoma (SCC) is recommended to diagnose this type of skin cancer. A physician will collect information such as symptoms and signs of SCC through asking health questions and by carefully examining the problem area/s.
Once the physician makes a determination and/or suspects an individual may have SCC, a skin biopsy is performed to provide a more detailed analysis. This skin sample is sent to the lab, where it is tested for the presence of cancer cells. For the most part, biopsies are reliable tests to screen for cancer.
