<unk>  squamous cell carcinoma is the end product of an unregulated proliferation of mucous basal cells. A single precursor cell is transformed into a clone consisting of many daughter cells with an accumulation of altered genes called oncogenes. What characterizes a malignant tumor over a benign one is its ability to metastasize. This ability is independent of the size or grade of the tumor (often seemingly slow growing cancers like the adenoid cystic carcinoma can metastasis widely). It is not just rapid growth that characterizes a cancer, but their ability to secrete enzymes, angiogeneic factors, invasion factors, growth factors and many other factors that allow it to spread.
