Name: Period: Cancer Epidemiology P-E-O Probe(Predict – Explain – Observe)PredictAs we have learned, cancer is caused by mutations occurring in genes that make proteins that are involved in maintaining a healthy cell cycle. For this reason, cancer is described as a genetic disease.Circle the statement below that you believe best describes the pattern of distribution of cancer in the human population around the world.A. All cancers have the same pattern of occurrence in every country.B. Cancers will have the same pattern of occurrence in economically developed countries, but different patterns in economically developing countries.C. There will be no pattern regardless of economic status.ExplainDescribe your thinking behind your choice. Provide an explanation, with evidence from previous lessons, for your answer.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ObserveYou will be given data from the American Cancer Society on the distribution of cancer and cancer types around the world. As you analyze the data, look for trends and patterns. Write your observations below:Observations – Identify up to 10 patterns based on evidence from the data sets.12345678910List 3 things that surprised you as you reviewed the data:123Review your original prediction and explanation. Does the data support what you predicted? Write a statement as to whether your prediction has been supported by the data or not and what you think this indicates about the causes of cancer._______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________American Cancer Society: Global Cancer Facts & Figures(2011 Report)Name: Period:Inside Cancer WebquestAdapted from a lesson shared on the Inside Cancer website.Go to on “Hallmarks of Cancer” above.What are the 7 “hallmarks of cancer” that a cell must have to become cancerous? Write one sentence describing each. The first one is done for you.Uncontrolled Growth_____________________________Cancer cells grow without the signal to grow. They also ignore signals to stop growing._______________________________ _____________ Cancer Epidemiology543560012065Click on “Causes and Prevention” above.Label the pie chart at right.

Environmental cause:Click on “smoking” in the menu to the left.Smoking: Killers in Smoke: What do smoke particles (soot) do to the lung cilia?How does this cause lung cancer?Name: PeriodPutting It All TogetherEpidemiological study of cancer shows that in countries with high rates of some types of cancers, not all people living in the same environment develop that cancer. In fact, in a family of four, only one individual may develop cancer while others do not.825501492885CLAIM: FACTORS SUCH AS ERRORS IN REPLICATION, MEIOSIS, AND ENVIRONMENTALLY INDUCED MUTATIONS CAUSE VARIATION. 020000CLAIM: FACTORS SUCH AS ERRORS IN REPLICATION, MEIOSIS, AND ENVIRONMENTALLY INDUCED MUTATIONS CAUSE VARIATION. According to the American Cancer Society’s Global Cancer Facts & Figures report published in 2011, external causes of cancers include environmental factors such as tobacco, chemicals, radiation and infectious organisms; internal causes include inherited mutations. The chance that an individual will develop cancer in response to a particular environmental agent depends on several interacting factors —how long and how often a person is exposed to a particular substance, his/her exposure to other agents, genetic factors, diet, lifestyle, health, age, and gender.What biological events or processes contribute to genetic variation that could make one individual more susceptible to developing cancer than another?Write an argument to persuade another biologist that your claim is valid and acceptable. As you write your argument, remember to do the following:State the claim you are trying to support including at least 3 biological events or processes that contribute to genetic variation.Include genuine evidence (facts, models, statistics, diagrams) For each process identified, justify why the evidence is relevant and why it provides adequate support for the claim.Include appropriate and relevant scientific vocabulary to enhance your response.Putting It All TogetherYour Claim:Your EvidenceYour Justification of the EvidenceProcess 1Process 2Process 3Name: Period:Biology Common Writing TaskEpidemiological study of cancer shows that in countries with high rates of some types of cancers, not all people living in the same environment develop that cancer.
