Basal Cell Carcinoma Staging Staging is the process of determining whether cancer has spread and, if so, how far.
Stage 0. Cancer is found only in the original tumor in the skin. It is only in the epidermis and has not spread to the dermis. Stage 0 is also called carcinoma in situ.
Stage 1. The tumor is 2 centimeters wide or smaller. It may have spread into the dermis. Cancer does not invade the muscle, cartilage, or bone and has not spread to lymph nodes or other organs.
The tumor needs to have no more than two high-risk features. All Rights Reserved. EN NL. Skip to content. How does basal cell carcinoma form? By SkinVision in Articles. Table of contents.

Why it forms Most basal cell carcinomas are a result of long-time, repeated sun-exposure or occasional intense sun-exposure. Who is at the greatest risk Anyone can develop this type of cancer but it is more common in light-skinned individuals with blonde or red hair and light green or blue eyes.
BCC symptoms Basal cell carcinoma typically presents itself as a waxy or pearly white bump or nodule on the face ears or neck. How to stay safe Basic precautions can be taken to limit your chance of developing basal cell carcinoma, or most types of skin cancer for that matter.
Limit time spent in the sun. When in the sun, wear sunscreen reapplying every few hours and protective clothing. Know the skin cancer warning signs of a mole or blemish. The epidermis is separated from the deeper layers of skin by the basement membrane. When a skin cancer becomes more advanced, it generally grows through this barrier and into the deeper layers.
Basal cell carcinoma also called basal cell skin cancer is most common type of skin cancer. About 8 out of 10 skin cancers are basal cell carcinomas also called basal cell cancers. These cancers usually develop on sun-exposed areas, especially the face, head, and neck. They tend to grow slowly. But if it's left untreated, basal cell cancer can grow into nearby areas and invade the bone or other tissues beneath the skin. If not removed completely, basal cell carcinoma can come back recur in the same place on the skin.
People who have had basal cell skin cancers are also more likely to get new ones in other places. About 2 out of 10 skin cancers are squamous cell carcinomas also called squamous cell cancers.
These cancers start in the flat cells in the upper outer part of the epidermis. These cancers commonly appear on sun-exposed areas of the body such as the face, ears, neck, lips, and backs of the hands.
They can also develop in scars or chronic skin sores elsewhere. They sometimes start in actinic keratoses described below.
