Textbook Question
Chapter 22, Problem 3CT
Ultimately, cancer kills because it spreads and disturbs homeostasis. Consider, for example, a kidney cancer that metastasizes to the lungs and liver. What are some specific aspects of homeostasis that the spreading disease could affect?

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.
Cancer is one of the leading causes of death in both men and women. Caring for the cancer patient and family requires a multidimensional approach.
What does it mean to provide a multidimensional approach?
Name a toxicant that requires chronic exposure to cause cancer, and another that is driven by acute exposure. Comment on the modes of action that each of these examples you provide utilize to cause cancer (in other words, does it alter cell signaling, does it alter metabolism, DNA, RNA, Protein synthesis, etc?)

- Which of the following statements related to Radiation Therapy is FALSE? Radiation therapy works by damaging the DNA within cancer cells and destroying their ability to reproduce. When the damaged cancer cells are destroyed by radiation, the body naturally eliminates them. ONormal cells are affected by radiation, but they are able to repair themselves. Radiation therapy is the only treatment a patient with cancer needs.arrow_forwardWhat is the difference between the terms infection and disease? Disease refers to the invasion of a pathogen into the body, while infection means that the body's normal function is disrupted. Infection refers to the invasion of a pathogen into the body, while disease means that the body's normal function is disrupted. Infection refers to disease caused by microbes, while disease is the broader term used for any abnormal functioning of the body. Infection means that a pathogen has adhered to the body's skin or mucous membranes, while disease means that the pathogen has invaded the body.arrow_forwardWhat are two health disparities that cancer could be believed to exist in a community, city, or state?arrow_forward
- Platelet-derived growth factor (PDGF) is, as its name suggests, stored in and secreted by platelets. Platelets release PDGF in the vicinity of wounds as part of their participation in the clotting response. PDGF, in turn, stimulates the proliferation of nearby fibroblasts, which help in the wound healing process. When, however, the PDGF gene is mutated or inappropriately expressed, it can lead to cancer. Why, then, does the wound healing response not lead to similar uncontrolled cell division?arrow_forwardResearch a cancer caused by an oncogenic virus. how the virus disrupts normal cell function and causes cancer to develop. What risk factors exist that make individuals more susceptible to this type of disease? Are there any preventative measures that can be taken to mitigate the risk of contracting this disease? What therapies are available or being developed that combat this disease? what are the methods of action for all therapies available.arrow_forwardWrite an 800-word essay on debunking this myth about cancer from "Myth Buster by Ted Koren 2012 Issue 5”: MYTH: The cancerous tumor is trying to kill us. FACT: New research reveals that the tumor has a purpose. Andreas Moritz, in Cancer is NOT a disease – It’s a survival mechanism, explains that cancer is a response to internal toxicity. Cancer is how the body tries to keep us alive when we are in danger of imminent death from poison; cancer cells feed off our toxic buildup. Only by addressing the cause of the tumor can we have a real cure. The tumor is so important to the body that it is supplied with special blood vessels. Why would the body try to destroy itself? It makes more sense that the tumor is serving a purpose.arrow_forward
- Explain the following figure. According to this model, what are the two major phases of metastasis that must be successful for metastasis? What are the challenges faced by cancer cells during metastatizing?arrow_forwardA lymphadenectomy (lymph = clear fluid + aden = gland + -ectomy = excision) is a surgical procedure that involves the removal of lymph nodes. It is an invasive procedure that is performed to slow or stop the spread of cancer cells through the body from an original tumor site. Describe why this procedure might be effective in stopping the spread of cancer, even though it involves removing lymph nodes that are filled with the cells engaged in destroying unwanted substances and cells.arrow_forwardHow detrimental are the effects of using conventional radiography, for dental purposes, on a patients risk of contracting cancer?arrow_forward
- Cancer is a complicated series of diseases characterized by over-proliferation of cells within a tissue. While in some instances the primary tumor is the ultimate cause of death, in many cases the primary tumor metastasizes, or moves, through the lymph system to invade other tissues. The migration of tumor cells requires changes in the adhesion properties of the cell that allow it to move and invade more readily. There are several molecules involved in cell-to-cell connections and cellular architecture: laminins, matrix metalloproteinases, cadherins, and integrins. While mutations in genes that control the cell cycle or recognize DNA damage are the causes of tumor cell formation, tumor cell spread to other tissues may be caused by mutations in the genes the code for these extracellular proteins. The loss of cellular connections, cellular identification and signaling, and tissue structure may lead to the release of expanding tumor cells into the circulatory and lymphatic systems. Once…arrow_forwardMetastasis is the spread of cancer to new tissue/regions within the body. Using breast cancer as an example, explain how the lymph system could facilitate metastasis.arrow_forward##2.Cancer starts from cells that start to grow uncontrollably fast. They destroy tissues and organs. What does this say about the effects of diseased cells on the higher levels of organization in an organism? a. Cancer involves only certain kinds of cells and does not affect any other kind of cell. b. Diseased cells affect only the next higher levels of organization that they make up (tissues). c. Diseased cells damage the higher levels of organization they make up tissues, organs, organ systems, and eventually the whole organism. d. Diseased cells do not affect the other parts of an organism. e. Cancer cells cannot propagate easily..arrow_forward
