Basal cell carcinoma is a cancerous condition that causes lesions in the skin. These types of cancers are specific to the basal cells.

What Are the Causes of Basal Cell Carcinoma?

The leading cause of basal cell carcinoma is the mutation happening in the DNA (deoxyribonucleic acid). The outermost layer of the skin is known as the epidermis. The basal cells that are responsible for the occurrence of basal cell carcinoma are found below the epidermal layer. These cells try to produce new cells in response to the mutation. The new cells cause the older cells to move from their original position, and they are sloughed off later after dying. The newly formed cells undergo vigorous proliferation resulting in the formation of cancerous cells. In the later stages, it begins to appear on the skin as a lesion.
