Are we being harmed because we receive too much, instead of too little, medical care?
For many Americans, the answer is increasingly "yes."
Just last month, a new study showed a link between the iodine contrast that patients receive for routine medical scans and thyroid disease. Researchers found that people with thyroid disease were two to three times as likely to have received this agent than those who did not develop it. Only two years prior, another study in the same journal, Archives of Internal Medicine, estimated that radiation from medical scans was responsible for up to 30,000 new cases of cancer and 15,000 deaths every year.
