CHAPTER 19:
Answer the following critical thinking questions. Use the Internet as a resource.
1. The term neoplasm refers to tumors that are masses or growths that arise from normal tissue. A growth can occur at any time in life. Are all neoplasms life-threatening?
2. There are agents in the environment that, upon exposure, are known to increase an individual’s risk of developing cancer. What are some of those environmental agents, and how do they contribute to increasing cancer risk?
3. Radiation therapy is a way of treating cancer by irradiating the tumor with a maximal dose of ionizing radiation in order to destroy the cells. Exposure to radiation, however, poses a risk in itself for increasing the development of cancers. How does cancer therapy reconcile this risk?
CHAPTER 20:
1. Henry was climbing a tree when he fell and hurt his arm. His mother took him to the emergency room where she demanded to see a doctor. After an initial examination, she was surprised that she saw little of the doctor and instead saw many other health professionals who were involved in determining whether Henry’s arm was indeed broken. What sort of personnel might be involved in diagnosing the condition of Henry’s arm?
2. Dr. Fuller has a patient she suspects has a malfunctioning thyroid gland. She is not certain about the nature of the problem and would like to obtain information about this patient. What type of diagnostic tool should she use, and what sorts of information might she obtain about the state of the thyroid?
3. How can one patient have a radiologic procedure to diagnose a condition, while another has radiation treatment to destroy a tumor?
4. Sonja is 42 years old and pregnant with her first child. Her doctor thinks she ought to have a procedure called amniocentesis to harvest fetal cells for genetic analysis. He tells Sonja that he will use a large needle inserted through her abdomen to obtain these cells from the amniotic fluid around the baby. He tells her that he will be able to visualize the needle so she needn’t worry about sticking her baby. She decides that she still thinks it is dangerous because of the radioactivity her baby will be exposed to. Need she be concerned?
