Who are these Americans who die for lack of insurance? Dr. Linda Harris, an ob-gyn in Oregon tells of Sue, a 31-year-old patient of hers. Sue was a single mom who worked hard  sometimes two jobs at once  to ensure that her beloved daughter would enjoy a better life.

Sue’s jobs never provided health insurance, and Sue felt she couldn’t afford to splurge on herself to get gynecological checkups. For more than a dozen years, she never had a Pap smear, although one is recommended annually. Even when Sue began bleeding and suffering abdominal pain, she was reluctant to see a doctor because she didn’t know how she would pay the bills.

Finally, Sue sought help from a hospital emergency room, and then from the low-cost public clinic where Dr. Harris works. Dr. Harris found that Sue had advanced cervical cancer. Three months later, she died. Her daughter was 13.

“I get teary whenever I think about her,” Dr. Harris said. “It was so needless.”

Cervical cancer has a long preinvasive stage that can be detected with Pap smears, and then effectively treated with relatively minor procedures, Dr. Harris said.

“People talk about waiting lines in Canada,” Dr. Harris added. “I say, well, at least they have a line to wait in.”

Based on the numbers from the Harvard study, a person like Sue dies as a consequence of lack of health care coverage every 12 minutes in America. As many people die every three weeks from lack of health insurance as were killed in the 9/11 attacks.

Health coverage is becoming steadily more precarious as companies try to cut costs and insurance companies boost profits by denying claims and canceling coverage of people who get sick. I grew up on a farm in Yamhill, Ore., where we sometimes had greased pig contests. I’m not sure which is harder: getting a good grip on a greased hog or wrestling with an insurance company trying to avoid paying a claim it should.
