Worried about cancer? Ask someone to marry you

 

Bloomberg News

When I mentioned my bout with breast cancer to a new acquaintance, his first question was, “Are you married?”

It was an unusual reaction — a more common query is whether I have kids. Later he told me that his daughter-in-law had been diagnosed with breast cancer while still in graduate school and that she and his son had moved in with him. He understood better than most people that being married makes it easier to cope with cancer.

The very next day the Journal of Clinical Oncology released a study offering more than anecdotal evidence that marriage is good for cancer patients.

Controlling for demographic factors such as age, race, education and household income, researchers who analyzed records of more than 730,000 cancer patients found that married patients did significantly better than single people. They lived longer, received better treatment and were more likely to be diagnosed before metastatic cancers developed.

It didn’t matter whether the unmarried patients were lifelong singles, divorced, widowed or separated. All did worse than demographically similar married patients.

“This study is the first to show a consistent and significant benefit of marriage on survival among each of the 10 leading causes of cancer-related death in the United States — lung, colorectal, breast, pancreatic, prostate, liver/bile duct, non-Hodgkin lymphoma, head and neck, ovarian and esophageal cancer,” the American Society of Clinical Oncology noted in its news release.

The study doesn’t explain exactly why marriage makes a difference. It’s possible that married patients just have better health insurance. But, the authors note, “even in nations with universal access to free care, such as Denmark, sociodemographic factors affect outcome in a multitude of health conditions.” (Insurance differences also wouldn’t do much to explain the disadvantage of widowhood, because widows tend to be covered by Medicare.)

“The most likely reason,” the authors conclude, “is that married patients have better adherence with prescribed treatments than unmarried patients.” They have someone to watch over them.

What about couples who aren’t formally married but in long- term relationships? What about widows with supportive kids? What about people with great friends? And what about unhappy marriages?

The study didn’t leave these people out. If it had — if it had measured only the difference between ideal marriages and lonely, miserable singles — the differences would presumably be even more distinct. In the big picture, marriage makes a difference.

Marriage is increasingly the big sociological divide in American life. Getting and staying married makes you part of a privileged elite.

As Charles Murray documents in his 2012 book Coming Apart, that divide tracks the income divide, with low-income whites much less likely to be married than their high-income counterparts. (I criticized a different aspect of Murray’s book in this column.) The causality is debatable. Maybe poorer people have a harder time getting married. Maybe being married makes it easier to earn more. Maybe some third factor causes both phenomena. But what is clear is that you’re most likely to have a better life if you’re married — even if, it turns out, you get cancer.

Friends are nice, but they are rarely equivalent to a spouse. The level of on-call commitment and intimacy is simply different. Your spouse knows you in a 24/7 way that few if any others do, especially in a society organized around the nuclear family rather than the extended one. (A spouse also multiplies your extended family by two.) As my economist husband likes to put it, being married also creates a “joint utility function.” Your happiness becomes entwined with your spouse’s, giving you strong incentives to make an extra effort.

Recalling how the “epidemic of care giving” in response to AIDS helped make the case for same-sex marriage, the writer Jonathan Rauch argued that by “assuming the burdens of marriage at its hardest,” gay men demonstrated that “no relative, government program or charity is as dependable or consoling as a dedicated partner.” What’s true of AIDS is true of cancer as well.

People don’t like to hear that. It’s not fair to single people. It’s not constructive. “Our results suggest that patients who are not married should reach out to friends, cancer support or faith-based groups, and their doctors to obtain adequate social support,” lead author Ayal Aizer, chief resident in radiation oncology at Harvard Medical School, said in the oncology society’s news release.

But trying to turn the study’s findings into a general call for “social support” ignores its stark result. Single people aren’t, of course, doomed to die of cancer. Their friends and family can in fact help them do better. But we shouldn’t pretend that marriage isn’t a huge advantage.

  • Ten truths about day jobs

    1. Never look down on somebody who holds a job and rides the bus to the end of the line. These are the people who labor their whole lives but are never rewarded with tangible success. Not every dog has its day; some simply work their tails off. My father was one of those guys: never missed a day, never missed a beat and barely made a dime. But he taught my brother and me how to get a job done. Old Italians would grab their kids and say, “The more you have in there,” pointing to our heads, “the less you have to put on there,” pointing to our backs. My brother and I benefited from my father’s integrity, his stamina and his gratitude for having a job.

  • I studied engineering, not English. I still can’t find a job.

    When I graduated from Penn State a year ago, I thought I was perfectly prepared to succeed in the business world. I’d worked hard, graduated at the top of my class in computer science and managed to acquire lots of experience with the sorts of industry software that I was sure hiring managers were looking for. I’d even chosen a STEM degree, which — according to just about everyone — is the smartest choice to plan for the future (eight out of the 10 fastest growing job occupations in the United States are STEM jobs).

  • The Beatles’ cry of freedom: ‘Money,’ 50 years later

    In early 1964, a friend called me up and asked if I wanted to hear the new Beatles album, With the Beatles. It had come out in Britain a couple of months before, but no one I knew had heard it, or for that matter heard of it. My friend’s father, an airplane pilot, had brought it back. It was just days after the Beatles’ first appearance on The Ed Sullivan Show.
