There were 81 people in Warren County who registered Thursday to take part in a groundbreaking American Cancer Society study to be conducted over the next 30 years.The goal is to help determine causes of cancers – and ways to prevent it – through analyzing lifestyle, behavioral, environmental and genetic factors. The study’s best-case scenario would be to eliminate cancer as a major health problem for this and future generations. This is the American Cancer Society’s third Cancer Prevention Study and is aptly named CPS-3.Local resident Monika Hopkins is glad to be part of a study that might find a cure for cancer.
