ABSTRACT
NEOPLASIA comes from the Greek words neo, meaning new, and plasis, meaning molding. Cancer has reached epidemic proportions in human and veterinary medicine and it should come as no surprise that close to 40% of the cases that come into a veterinary referral facility are cancerous disorders. Therefore, it behoves the clinician to know when to biopsy a tissue that might be neoplastic. Cancer can involve any tissue of the body and this, therefore, offers a clinician the opportunity to observe several interesting disorders. The two main diagnostic modalities are imaging and biopsy, but it is still essential to evaluate the entire patient in order to appreciate the full scope of the disease at hand. Many of the lesions illustrated will be available to visualization and palpation, thus making a thorough physical examination an essential part of the diagnostic evaluation.
