Basal cell

Basal cell refers to the cells located at the base of the epidermis, the outermost layer of the skin. These cells are responsible for producing new skin cells as old ones die off. Basal cells have a cuboidal shape and are primarily involved in the process of cell division to replenish the skin's surface.

Function

Basal cells play a crucial role in maintaining the health and integrity of the skin. They continuously divide and push older cells toward the skin's surface. As these older cells move up through the layers of the skin, they flatten and eventually die off to form the skin's protective outer layer, known as the stratum corneum.

Basal Cell Carcinoma

Basal cell carcinoma is a type of skin cancer that originates in the basal cells. It is the most common type of skin cancer and is often caused by long-term exposure to ultraviolet (UV) radiation, either from the sun or from tanning beds. Basal cell carcinoma typically appears as a small, shiny bump or nodule on the skin, often on areas most exposed to the sun, such as the face, ears, and neck.

Treatment

Treatment for basal cell carcinoma depends on the size, location, and stage of the cancer, as well as the patient's overall health. Options may include surgical removal, Mohs surgery, radiation therapy, cryotherapy, topical treatments, or a combination of these.
