According to the American Cancer Society, breast cancer is the second most frequent cancer type (after lung cancer), with 15% incidence.  It is estimated that more than 200,000 new cases will be diagnosed before the end of 2010.  However, there is much hope and optimism: in the last 30 years the death rate has been decreasing for all ethnic groups, the rate of new cases has been declining in the last decade, and there are now about 2.5 million breast cancer survivors in the US.  The first Susan G. Koman Race for the Cure took place in 1983, and 27 years later, these 5K runs/fitness walks are going strong. 25% of the net income from each race supports the Komen for the Cure Award and Research Grant Programs, while up to 75% of the income supports local community efforts funding breast health education and breast cancer screening efforts. Many factors may influence the incidence of breast cancer and NSDL has resources to help teachers guide their students in learning about them.  For example, the New Animal Study May Explain Why Alcohol Consumption Increases Breast Cancer Risk is a report that our partners at the BEN Pathway make available to us along with many other related sources, such as the What Is Breast Cancer?  Another possible risk factor in breast cancer is presented in the report Breast Cancer Risk and Drinking Water Contaminated by Wastewater from the Engineering Pathway.  The online textbook Oral Contraceptives and Breast Cancer from the National Academies Press presents yet another suspect in the fight against breast cancer. If you are looking for visuals, the Pictures of Breast Cancer Diagnosis from our AMSER Pathway partners or the Genetic Therapy and Breast Tumors movie from our Teachers’ Domain partners could be your answers.  For more hands-on types of activities, You be the Radiologist! from the Teach Engineering collection of the Engineering Pathway would have your students create a 1-D strain plot in Microsoft Excel depicting the location of a breast tumor amidst healthy tissue.  Finally, your work as a teacher bringing cancer education to our youth is essential to win this battle, thank you very much!
