What is basal cell carcinoma?

Basal cell carcinoma is a type of skin cancer that originates specifically from the basal cells, which are found in the outermost layer of the skin, known as the epidermis. These basal cells are responsible for producing new skin cells as the old ones die off, and when they undergo mutations, they can lead to the development of cancer.

Because basal cell carcinoma arises from the outer layer of the skin, it is classified among the most common forms of skin cancer. This makes the identification of its origin crucial for understanding its behavior and treatment. It typically presents as a small, shiny bump or a sore that does not heal, often found in sun-exposed areas of the body.

Understanding the correct origin of this carcinoma helps in determining the risk factors involved, the likelihood of metastasis, and the overall management of the condition, which usually involves surgical removal or other targeted therapies.
