Every year, about a million Americans are diagnosed with cancer. This means that about 75 million Americans now living will eventually have cancer, And one in five will die of the disease. There are many kinds of cancers and many causes, such as smoking, overexposure to ultraviolet rays, a high fat and low fiber diet, and some workplace chemicals. Hundreds of millions of dollars are spent each year on searching for treatment, yet less money is spent on prevention. Should we devote more

- This is a blank question. Thank you in advance, Bloom Syndrome Bloom syndrome is a rare genetic disorder. It is characterized by short stature and a long narrow face with prominent nose and ears. There is also increased sensitivity to light. People who have the disorder often develop rashes on their face, forearms, and hands when they have been exposed to the sun. In addition, these people often suffer from chronic obstructive pulmonary disorder (COPD) and have a higher chance of developing cancer. The cause of this genetic disorder is a mutation in the BLM gene located on chromosome 15. The immediate effect of this mutation is that there is a defect in the functioning of the DNA helicase enzyme. What would be the effect of this mutation on DNA replication? What stage of the cell cycle would be most affected?New cases of cancer are expected to increase in the ensuing years. How can estimating the future burden of cancer help us to prepare for this? Give detailed examples of different types of cancer and the trends that will likely be observed. What can we realistically expect to achieve regarding cancer risk reduction? Why is it important to have cancer statistics databases?Write 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.
- "The main causes of cancer are the products of our highly industrialized way of life such as pollution and food additives" is true or false.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 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?
- 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?Mrs. 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?Why is it inaccurate to say, “Smoking causes cancer”?
- Why are deaths from infection in cancer patients so common?name any two methods that can possibly cure cancer .Figure 17.15 In 2011, the United States Preventative Services Task Force recommended against using the PSA test to screen healthy men for prostate cancer. Their recommendation is based on evidence that screening does not reduce the risk of death from prostate cancer. Prostate cancer often develops very slowly and does not cause problems, while the cancer treatment can have severe side effects. The PCA3 test is considered to be more accurate, but screening may still result in men who would not have been harmed by the cancer itself suffering side effects from treatment. What do you think? Should all healthy men be screened for prostate cancer using the PCA3 or PSA test? Should people in general be screened to find out if they have a genetic risk for cancer or other diseases?
