What is Invasive moderate to poorly differentiated squamous cell carcinoma?

Invasive moderate to poorly differentiated squamous cell carcinoma (SCC) is a type of skin cancer characterized by the abnormal growth of squamous cells, which are flat cells found in the outer layer of the skin and other tissues. The term "moderate to poorly differentiated" indicates that the cancer cells lack the normal structure of healthy squamous cells, making them less recognizable and more aggressive. This differentiation grade suggests a more advanced stage of the disease, often associated with a worse prognosis due to its potential for invasion and metastasis. Treatment typically involves surgical removal, radiation, or chemotherapy, depending on the extent of the cancer.
