Democratic presidential hopeful John Edwards said on Sunday that his universal health care proposal would require that Americans go to the doctor for preventive care.

"It requires that everybody be covered. It requires that everybody get preventive care," he told a crowd sitting in lawn chairs in front of the Cedar County Courthouse. "If you are going to be in the system, you can't choose not to go to the doctor for 20 years. You have to go in and be checked and make sure that you are OK."

He noted, for example, that women would be required to have regular mammograms in an effort to find and treat "the first trace of problem." Edwards and his wife, Elizabeth, announced earlier this year that her breast cancer had returned and spread.

Edwards said his mandatory health care plan would cover preventive, chronic and long-term health care. The plan would include mental health care as well as dental and vision coverage for all Americans.
