Squamous Cell Carcinoma
Of the many different types of skin cancer, three are the most common: melanoma, squamous cell carcinoma and basal cell carcinoma. This post will take a closer look at squamous cell carcinoma, which is the second-most common type of cancer after basal cell carcinoma.
Squamous cells comprise the very most outer layer of skin. Squamous cells are found not just on the skin, but also in several different parts of the body, including the stomach, lungs and mouth. These cells may also develop cancer, but the symptoms typically present themselves differently than the skin version of squamous cell cancer.
Squamous cell carcinoma typically presents itself as a small growth, typically on the face, head or neck, that eventually looks like a superficial ulcer. Unlike basal cell carcinoma, squamous cell cancer does carry a significant risk of metastasis (spreading to other parts of the body), with about 4 percent of cases metastasizing. However, like basal cell, squamous cell cancer is rarely fatal, especially with early diagnosis and treatment.
The greatest risk factor for developing squamous cell carcinoma is sun exposure. Those who are exposed to a lot of sunlight, particularly light-skinned people, are at higher risk. People who have weak immune systems are also more likely to develop skin cancer. The best preventative measures one can take is to avoid prolonged sun exposure and to wear sunscreen with a sun protection factor (SPF) greater than 30.
If you think you may have squamous cell carcinoma, you should see a dermatologist immediately. Your doctor will perform a biopsy on the area in question and will be able to make a diagnosis. If you do have cancer, there are several treatments that can effectively treat squamous cell cancer, such as radiation therapy or surgery.
