Cancer in the brain O is more common in the 25-50 age group than in any other age group. O can be a metastasis from a cancer elsewhere in the body. O none of these. O all of these. O occurs less often than spinal cord tumors.

A brain tumor is found in a CT scan of Mr. Child's head. The physician is assuming that it is not a secondary tumor (i.e., it did not spread from another part of the body) because an exhaustive workup has revealed no signs of cancer elsewhere in Mr. Child's body. Is the brain tumor more likely to have developed from nerve tissue or from neuroglia? Why?

Typical neurons are not able to perform mitosis after maturity. A patient has just been diagnosed with brain cancer and is undergoing treatment. Based on what you know about cell division and cancer, why does this seem unusual?

Contrast - colon cancer; whose incidence increases dramatically with age (as shown in the figure); incidence of osteosarcoma, a tumor that occurs most commonly in the long bones, peaks during adolescence. Osteosarcomas are relatively rare in young children (up to age 20) and adults (over 20). Why do you suppose that the incidence of osteosarcoma does not show the same sort of age dependence as colon cancer? (5 pts) By analogy with automobiles, defects in cancer-critical genes have been likened to broken brakes and stuck accelerators, which are caused in most cases through faulty service by bad mechanics. Using this analogy, decide how oncogenes, tumor suppressor genes, and genome maintenance genes relate to broken brakes, stuck accelerators, and bad mechanics. Explain the basis for each of your choices. (6 pts)
