Though the specific tumor biology, implantation site, host status, mode of growth, and the nature of associated treatments preclude development of precise guidelines for the upper limits of tumor size, the following general guidelines should be followed: Scientific staff responsible for monitoring the animal on tumor study should not only be familiar with normal animal health and behavior, but must also be able to observe adverse changes in health, behavior, or tumor burden.
