IS SKIN CANCER MALIGNANT?

All cancer is malignant; but if treated early enough, some skin cancers are less likely to spread than others, like the two most common skin cancers, Basal Cell & Squamous Cell Carcinoma. These tend to metastasize much slower than their deadlier cousin, Melanoma. 

Left untreated; however, all skin cancers can become disfiguring and/or deadly.
