Stage 3 basal cell carcinoma (BCC) is a more advanced form of this common skin cancer where the lesion has grown larger and may have spread to nearby structures or lymph nodes.
Here's a more detailed breakdown of what defines Stage 3 BCC:
-
Size: The BCC skin lesion is typically larger than 4 centimeters (about 1.6 inches) in diameter.
-
Local Invasion: The cancer has grown into deeper tissues and nearby structures such as:
- Bone
- Cartilage
- Nerves
-
Lymph Node Involvement: The cancer may have spread to one nearby lymph node. The lymph node will typically be less than 3 centimeters (a little over an inch) in size. Critically, the cancer has not spread to distant sites (metastasis).
In summary, Stage 3 BCC represents a significant progression from earlier stages, characterized by its size, invasion of nearby tissues, and potential spread to regional lymph nodes. Early detection and treatment are crucial in preventing BCC from reaching this advanced stage.
