"Melanoma usually presents as a lump or bump and typically is fairly obvious to owners and veterinarians. The precise diagnosis of this type of cancer requires microscopic evaluation of cells and/or tissue samples.  It can be difficult even for a skilled veterinary pathologist to determine whether melanoma is malignant or benign.   Radiographs (X-rays) are commonly used to assess whether the disease has metastasized \u2013 especially whether it has spread to the lungs."^^<http://www.w3.org/2001/XMLSchema#string>
