Molecular Epidemiology of Lymphoma Patients

This study will include individuals diagnosed with lymphoma and individuals with no history of cancer. Half of the participants in this study will have lymphoma, and half will have no history of cancer. Information from both groups will be compared to help researchers try to learn which factors may lead to the development of lymphoma. If you agree to take part in this study, you will be asked to complete a questionnaire at M. D. Anderson. In this questionnaire, you will be asked about your demographics (such as your age, sex, etc.), certain environmental exposures (such as pollution), your medical history, family history, diet, and your past and present smoking and alcohol use habits. This questionnaire should take about 50 minutes to complete. You will also have about 2 ½ tablespoons of blood drawn for special tests. These tests will look for any biologic factors (such as changes in your DNA) that may be linked to lymphoma. You will not be informed of the results of any of the testing done with your blood samples. Your participation will be over in this study once your blood has been drawn. This is an investigational study. Up to 800 participants will take part in this study. All will be enrolled at M. D. Anderson.
