Researchers have argued that the U.S. experiences avoidable mortality, defined as death before the age of 75, from conditions that are either preventable through effective public health and primary prevention or treatable when detected early and effective care management is provided.
Death from diabetes, certain infections, breast and colon cancer, appendicitis are just some examples of avoidable mortality.
