What is sqamous cell carcinoma?

Squamous cell carcinoma (SCC) is a type of skin cancer that affects the squamous cells. Squamous cells are flat, scale-like cells that are found on the surface of the skin. SCC is the second most common type of skin cancer, after basal cell carcinoma.

SCC is caused by exposure to ultraviolet (UV) radiation from the sun or from artificial sources, such as tanning beds. UV radiation can damage the DNA in squamous cells, leading to the development of cancer.

SCC can appear anywhere on the body, but it is most common on areas that are exposed to the sun, such as the face, neck, arms, and legs. SCC can also occur in areas that are not exposed to the sun, such as the genitals, mouth, and throat.

SCC typically appears as a red, scaly patch of skin. The patch may be raised or flat, and it may bleed or crust over. SCC can also appear as a wart-like growth or as a sore that does not heal.

SCC can be diagnosed by a biopsy, which is a procedure in which a small piece of skin is removed and examined under a microscope.

Treatment for SCC may include surgery, radiation therapy, chemotherapy, or targeted therapy. The type of treatment that is used will depend on the stage of the cancer and the patient's overall health.

SCC can be prevented by avoiding exposure to UV radiation. This can be done by seeking shade, wearing protective clothing, and using sunscreen.
