Signs and Symptoms
The most common location for basal cell carcinoma is on sun-damaged skin, especially the following areas:
- Face
- Head
- Neck
- Chest
- Upper back
However, basal cell carcinomas can occur on any part of the skin, except for the palms and soles.
Nodular basal cell carcinomas are described as "pearly" in appearance. They are usually skin-colored or pink bumps, and tiny blood vessels (telangiectasias) can frequently be seen on their surfaces. As a basal cell carcinoma grows, it can develop a shallow depression in its center, and bleeding with minor trauma can occur.
Infiltrating or morpheaform BCCs tend to appear as scar-like growths on the skin. They can be slightly shiny, and sometimes have telangiectasias, sores (erosions), or scabs on their surfaces. These skin changes can be subtle.
Superficial BCCs often appear as pink or red dry, scaly spots. They slowly enlarge and may develop a raised edge. Often, people mistake a superficial BCC as a dry patch of skin or a non-itching rash that won't go away. This subtype of BCC is most often found on the trunk (chest or upper back), arms, or legs.
