Squamous cell carcinoma is a common form of skin cancer that originates in the epidermis layer of the skin, and happens after skin is exposed to the sun for many, many years; because of this people usually don't develop the skin cancer until later in life. That is, unless you're prone to going to tanning salons which happens to increase your risk of SCC. The cancer is diagnosed with a skin biopsy, where a dermatologist takes a skin tissue sample and then runs it through a series of tests to determine whether or not a person has skin cancer. When it comes to treatment of SCC, it depends on the factors of how deep the cancer it is and how far it has spread. Multiple options are available including excision, Mohs Surgery, radiation, curettage and electrodesiccation, photodynamic therapy, laser treatment, and chemotherapy cream. Most of these are recommended in early stages of the disease to prevent further damage of the skin and tissue. To prevent such a disease, it is recommended to perform skin self-exams scans if you think you are at risk of a skin disease, protect your skin from outdoor rays and indoor tanning by using sunscreen and lip balm that offer protection from the sun, condoms which can prevent spread of HPV and reduces the risk of SCC on the genitals, and limiting the amount of alcohol and smokes, both of which increase your risk of getting SCC in your mouth.
