Textbook Question
Chapter 11, Problem 22BS
There are genetic tests for several types of "inherited cancer.” The results cannot usually predict that someone will get cancer. Rather, they indicate only an increased risk of developing cancer. For many cancers, lifestyle changes cannot decrease risk. Therefore, some people consider the tests useless. If your close family had a history of cancer and a test were available, would you get screened? What would you do with this information?

A woman has just been diagnosed with breast cancer. Her doctor
tells her that while cancer is a multifactorial disease, she
carries the breast cancer susceptibility gene, BRCA1. One of her
two identical twin 19-year-old daughters is afraid that she also
may have inherited the gene.
-What considerations would you give her daughter who is worried
about inheriting the cancer gene?
Describe two mechanisms by which genetic change causes cancer.

- With regard to cancer cells, which of the following are true? A. Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation. Cells usually accumulate many mutations over time, and this results in cancerous growth. B. Almost all cancers are caused by oncogenic viruses. no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body. DE. Cancer cells are unable to control their division.arrow_forwardWhat is the difference between saying that cancer is inherited and saying that the predisposition to cancer is inherited?arrow_forwardMrs. Berk is 65 and has terminal cancer. The nurse tells you the doctor has told Mrs. Berk and her family that further treatment will not stop the cancer. You have cared for Mrs. Berk during several hospital stays and are assigned to give her care today. When you go to her room, she tells you that she will be happy if she can live just long enough to see her grandson graduate from high school in the spring. Later when you go to her room, she is crying and says she does not understand why this is happening to her. 1. What stage or stages of grief does Mrs. Berk seem to be experiencing? What evidence do you have for your answer?2. What communication techniques would you use to help Mrs. Berk? How comfortable are you in using these techniques? Why do you feel as you do?arrow_forward
- Although cancer is not a contagious disease in humans or other vertebrates, there have been rare cases in which cancers have spread from one organism to another. Describe three cases of these contagious cancers and what conditions might have led to their appearance. For an introduction to this topic, see http:// www.cancer.org/cancer/cancerbasics/is-cancer-contagious.arrow_forwardCancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?arrow_forwardname any two methods that can possibly cure cancer .arrow_forward
- b) What is one reason that it is challenging to treat cancer?arrow_forwardWhat separates cancer cells from normal cells? Describe one form of mutation that can increase the risk of a normal cell being cancerous.arrow_forwardWhat is one type of cancer (in humans or other organisms) that you are familiar with or interested in? How often does this cancer occur? What are some genetic causes of this type of cancer?arrow_forward
- Please discuss the difference between cancers caused by tumor viruses and cancers caused by oncogenes. Does the etiology of a cancer influence its manifestation?arrow_forwardThe current way to gauge the effectiveness of chemotherapy is to track the size of the tumor. If the tumor shrinks, the chemotherapy is said to be "working." If cancer stem cells really do act the way we think they do, what will be the new way that the effectiveness of chemotherapy will be evaluated?arrow_forwardDiscuss the interplay between genetics and environment in the development of cancer (it would be helpful to focus on one tumor suppressor/disease to narrow the scope of the discussion). Which factor (genetics or environment) is playing a larger role within your chosen context? Justify your argument.arrow_forward
