Small Animal Oncopathology Practice Test

A characteristic of benign neoplasms is that they typically exhibit slow growth and have well-defined borders. This slow growth allows them to remain localized, unlike malignant tumors, which tend to grow rapidly and invade surrounding tissues. The well-defined borders of benign neoplasms make them distinguishable from malignant tumors, as they are often encapsulated or surrounded by a fibrous capsule, further preventing them from infiltrating adjacent structures. Benign neoplasms generally do not have the same aggressive growth patterns seen in malignant tumors, and their well-defined borders indicate that they can be more easily SAMPLEsurgically excised. The absence of characteristics such as invasiveness, potential for metastasis, and high cellular atypia distinguishes them as non-cancerous entities. This typically results in a more favorable prognosis for patients with benign tumors, as they are less likely to cause significant harm to the organism.
