Basal cell carcinoma is a type of skin cancer that causes a lump, bump or lesion to form on the outside layer of your skin (epidermis). These lumps form on areas of your skin that get a lot of sun exposure. Treatment to remove cancer from your skin leads to a positive outlook.
What is Basal Cell Carcinoma?
Basal cell carcinoma (BCC) is a type of skin cancer that forms in the basal cells of your skin. Basal cells exist in the lower part of your epidermis, which is the outside layer of your skin. Basal cell carcinoma looks like a small, sometimes shiny bump or scaly flat patch on your skin that slowly grows over time.
What are basal cells?
Basal cells are microscopic cells in the outer layer of your skin (epidermis), which is the skin layer that you can see and touch on your body. These cells are responsible for making new skin cells by dividing and copying themselves. When basal cells create new cells, the older skin cells push to the surface of your epidermis, where they die and leave your body.
What are the types of basal cell carcinoma?
There are four main types of basal cell carcinoma (BCC), including:
- Nodular: This is the most common type of BCC. Nodular BCC looks like a round pimple with visible blood vessels surrounding it (telangiectasias).
- Superficial spreading: This type causes lesions that appear as small, shallow marks on your skin that are slightly lighter in color than the surrounding skin. These lesions form on your trunk (torso), arms and legs.
- Sclerosing (morpheaform): These cancerous lesions look like scars that slowly expand over time. This type is most common on your face. This type can also take the form of a small red dot on your skin.
- Pigmented: This is a rare type of BCC that causes hyperpigmentation, where an area of your skin becomes darker than the skin surrounding it.
