The purpose of this study is to identify factors that influence cancer risk and to better understand the precursors to cancer so that preventive steps can be employed for individuals with and without inherited genetic mutations. Researchers also aim to develop a better understanding about which modifiers (a gene that changes the effect produced by another gene) cause some individuals to be at more risk for developing cancer. The study will collect information about personal and family history of cancer, along with personal demographics, medical history, lifestyle habits, and quality of life.
