During a routine check-up, a woman is informed by her doctor that she has developed a skin tumor. Although the woman is distraught, the doctor assures her that this is a benign tumor that will not spread to other parts of her body . Apparently, the mutation that led to the development of the tumor arose in one skin cell. After the skin tumor diagnosis, the woman and her male fiance ( who has not been diagnosed with a skin tumor) wonder whether they should start a family What is true? O All of the woman's children will inherit the mutation O All of the woman's children will inherit the mutation if the mutation is dominant O None of the woman's children will inherit the mutation © Some of the woman's children may inherit the mutation depending on which of her chromosomes they inherit

Mrs. Ortez has type III breast cancer and is now concluding the trial portion of a certain research study about this condition. She has responding well to the series of neoplastic medications and is currently in remmision. The researchers and her surgeon have informed both mrs Ortez and her husband that there is the possibility that her unique type of cancer could have a genetic foundation. Most at risk would be her 8 year old daughter, through both her 10 yr old and 2 yr old sons could carry the genetic mutation for this cancer. How do you, as her primary nurses, address her concerns for possible genetic testing of her children? Should the identification of the children's risk as possible carriers of this specific gene be identified at this time? Should the testing be even considered to be done at this time?
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?

What 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?
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.
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?
d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one. e)To cause cancer, tumor suppressor genes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one.
Cancer is a genetic disease. To provide evidence that you understand cancer genes are altered in both sporadic (somatic) and inherited cancers, match the beginning and end of the sentences below to give correct statements.
A couple has had a child born with neurofibromatosis. They come to your genetic counseling office for help. After taking an extensive family history, you determine that there is no history of this disease on either side of the family. The couple wants to have another child and wants to be advised about the risks of that child having neurofibromatosis. What advice do you give them?

Boldface one. b)Proteins that inhibit progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. c)What is the difference between a proto-oncogene and an oncogene? d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive).

Neurofibromatosis type 1 (NF1) is an inherited is an inheritent dominant disorder. The phenotype usually involves the production of many skin neurofibromas. Answer the following questions about the disorder: a) Are the NF1 neurofibromatosis-causing mutations that are inherited by affected children from affected parents likely to be loss-of-function or gain-of-function mutations? b) Neurofibromin, the protein product of NF1, is associated with the Ras protein. Ras is involved in the transduction of extracellular signals from growth factors. The active form of Ras is complexed with GTP; the inactive form is complexed with GDP. Would the wild-type neurofibromin protein favor the formation of Ras-GTP or Ras-GDP? c) Which of the following events in a normal cell from an individual inheriting a neurofibromatosis-causing allele could cause the descendents of that cell to turn into a neurofibroma? i. A second point mutation in…
