We’ve all done it. We’ve typed symptoms like “tingling, left arm” into Google, WebMD or any one of the myriad encyclopedic medical resources available on the Internet, before going to the doctor for an actual diagnosis. (Is it a stroke? Shingles? Carpal tunnel?)

Patients’ “Google stacks” (the printouts listing all their potential diagnoses) and “cyberchondria,” as some doctors refer to them, can be difficult for physicians to manage, says Dr. Zachary F. Meisel in his new column, Medical Insider, on Time.com. however, to “debate whether patients should or should not Google their symptoms…is an absurd exercise,” Meisel says, since patients are already doing it. plus, it often empowers patients and, in some instances, can make doctors’ jobs easier:

[T]here is no question that patients routinely benefit from going online before visiting the doctor. recently I saw a patient who came to the ER with a strange rash. she arrived with color printouts that correctly identified her condition. Not only was she correct in her self-diagnosis, but I am not sure I would have considered the right diagnosis so quickly if she hadn’t brought in the pictures.

So the real question is, How should doctors embrace and guide their patients’ online sleuthing in order to improve their care? To find out, check out this week’s Medical Insider.

Could Dean Gallo have beaten the disease if he’d had the bone scan and PSA test immediately after the backaches started, instead of six months later? “One thing I know is that he would have been dead a lot earlier if he hadn’t had the tests when he did,” says Betty Gallo. “But six months is a long time to wait; earlier it might have been controlled.” In fact, if Dean had been in the habit of getting a PSA test every year, he might still be alive today.

Like many men who get sick, Dean Gallo found himself in a state of deep denial. Yet the sad reality is that others might have taken even longer to uncover the cancer and confront the truth. Men are typically strangers to their own health. Preventive medicine and early detection rank way down on their list of priorities. And they frequently pay for it with their lives. Men are far likelier than women to die early from diseases, many of them treatable.

Of every 100,000 people, for instance, 297 men die of heart disease each year, but just 197 women. Cancer, likewise, takes 238 men per 100,000 compared to 163 women. In the United States, men live an average of six years less than women do. According to a Lou Harris poll, men were three times more likely than women to avoid doctors when they had persistent minor medical symptoms. Many neglected to seek routine screenings, even if sent reminders and offered free testing by their health plans.

Men’s mind-set toward medicine may be an artifact of their evolutionary past, when they faced so much danger and their life expectancy was so short they tended to discount the future and focused, instead, on immediate needs, theorize Margo Wilson and Martin Daly, a husband-wife team of evolutionary psychologists at McMaster University in Hamilton, Ontario.

“In the ancestral environment, women cared for dependent offspring, while putting food on the table and mating were the essential roles for men,” says Daly. “So if a woman detected infection or disease in herself, her appropriate response might have been to sequester herself and heal, while conceivably a man’s was to bring home another dead animal or quickly get laid.” instead of speeding off to a doctor, says Daly, “we’re still unconsciously asking ourselves, ‘Have I acquired enough goods? have I put enough dead animals in the fridge?’”

One male in this prehistoric mold is Eric Stonlower (name has been changed), a trucker from Portland, Oregon, who drove a rig to pay the mortgage while his wife stayed home with the kids. Transporting pallets of groceries across the Pacific Northwest for days on end, Stonlower had few opportunities for exercise and limited choices for meals. When he began feeling troubling signs—heartburn, nausea and shortness of breath—he didn’t know what they meant, and wouldn’t see a doctor for weeks. When he learned he’d suffered a heart attack (probably on the road) and had sustained heart damage, no one was more shocked than Stonlower himself.

“Before my heart attack, I pushed myself hard for overtime. After, I had to quit trucking, period,” he explains. Today working for the same company as a salesman (at lower pay), Stonlower maintains a low-fat diet and exercises regularly—but heart disease will always be a factor in his life.

In our evolutionary past, “a sense of invulnerability had great value in meeting challenges,” Wilson notes. “The early mariners were risk takers, and some of it really paid off. Striking out into the world against all odds has always been a very ‘guy’ thing.” to prevail, such men adopted a set of classic “male” traits: confidence, strength, toughness, independence, stoicism, fearlessness. But today, faced with fewer physical dangers, these same qualities can pose a risk to their health.

To alter the pattern, we must break through men’s emotional barriers. the strategy endorsed by Matthew Mintz of George Washington University is a national media blitz. Venues like the Superbowl, he suggests, would be perfect for promoting healthy male lifestyles: good nutrition, regular exercise, weight control, smoking cessation and, especially, regular physician checkups. Men should be coming in at least for a couple of blood pressure and cholesterol tests in their 20s, Mintz says, with additional tests like the PSA and colonoscopy being introduced in their 40s and 50s. “I guarantee that if there was a regular health segment on SportsCenter, men would become more interested in their health,” he insists.
