A group of Louisville-based doctors is trying to raise awareness among lawmakers about the dangers of tobacco.Surgeons and specialists from the James Graham Brown Cancer Center will travel to Frankfort Tuesday to offer information and free oral cancer screenings outside of the capitol.Thoracic surgeon Victor Van Berkel hopes lawmakers will be inspired to act to limit tobacco use."Currently we lead the nation in both tobacco-related cancers as well as the percentage of adults who smoke and use tobacco products and anything we can do to curtail that, I think will be beneficial to our population as a whole," he says.Van Berkel says the group isn't lobbying for any specific legislation, but they do support a statewide indoor smoking ban, similar to the law currently on the books in Louisville.
