Ottawa- Heart disease, move over and make room for cancer. That seems to be the unfortunate reality in Franklin County. Health Department Director Midge Ransom says cancer is now the number one cause of death in the county. Through education about the dangers of smoking, eating better and taking care of yourself, as well as advances in cardiovascular care, heart disease has seen a decline. However, Ransom says cancer rates have remained steady. Lung and breast cancer are two of the most common cancers seen.
