If cancer is fundamentally a genetic disease, how might an
environmental factor such as smoking cause cancer?
Tumor is a mass of tissues. It may be benign or malignant. The cellular growth that occurs when the cells divide uncontrollably is known as cancer. It arises as a result of fundamental defects in the regulation of cell division.
Step by step
Solved in 2 steps
- Which of the following mutations is MOST likely to cause cancer? A) a mutation that causes a cyclin gene to be expressed at all times during the cell cycle B) a mutation that causes an oncogene to be turned off so that no protein is made C) a mutation that causes a Cdk gene to be turned off so that no protein is made D) a mutation that causes a tumor suppressor gene to be over-expressedWhy do mutations in DNA repair genes increase the likelihood of developing cancer?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?
- What is the difference between saying that cancer is inherited and saying that the predisposition to cancer is inherited?How do normal cells protect themselves from accumulating mutations in genes that could lead to cancer? How do cancer cells differ from normal cells in these processes?Which of the following effectively describes the situation of someone with an inherited predisposition to cancer such as familial adenomatous polyposis or BRCA-associated familial breast cancer? Choose all that apply a) If they get malignant cancer, somatic mutations will not have been a factor b) Their cancer will most likely arise in their germ cells, not their somatic cells c) None of the answers effectively describes the situation d) Every cell of their body contains a gain-of-function allele of an oncogene e) Most cells in their body contain multiple cancer-causing mutations f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
- The "initiation" stage of cancer refers to: a) The stage where DNA is mutated, and permanent DNA damage occurs b) The stage during which the mutated cells develop into a malignant cell population c) The stage during which "promoters" enhance the further development of the mutated cells d) The stage during which cancer breaks away from the primary origin and metastasizesDuring 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 inheritCancer is a major public health problem. Both inherited genes and environmental factors play a role in the development of cancer. Associations have also been documented between environmental pollutants and cancer. In general, cancers caused by occupational or environmental exposures are pathologically and clinically indistinguishable from other cancers. However, some cancers have a very high probability of being occupationally related, such as angiosarcoma of the liver due to vinyl chloride exposure, and mesothelioma from asbestos fiber exposure. Documentation of exposures that cause cancer relies heavily on epidemiological studies. Unfortunately, there are complicating factors, such as the long latency period before the cancers are actually diagnosed, well after many other workers had already been exposed. Therefore, what must the prevention of occupational and environmental cancers rely upon to predict effects on humans and establish limits for human exposure?
