characteristics of benign and malignant tumors
Nothing is more important to the patient with a tumor than being told "It is benign." In most instances such a prediction can be made with remarkable accuracy based on long-established clinical and anatomic criteria, but some neoplasms defy easy characterization. Certain features may indicate innocence, and others may indicate malignancy. These problems are not the rule, however, and there are four fundamental features by which benign and malignant tumors can be distinguished. These are differentiation and anaplasia, rate of growth, local invasion, and metastasis.
