Unfortunately, men themselves are part of the reason for this state of affairs. Not only do many men not take care of themselves the way they should, they don't have the same attitudes about disease prevention that women tend to have. Consider this: Compared to women, men make half as many visits to their doctors for preventive care.
These differences become more acute as men pass the 50-year mark.
How come? First of all, many men are in denial about their prospects for becoming ill. For many men, getting sick or having a disease is viewed as a sign of weakness or failure. If you think like this, you don't have much motivation to go to a doctor for an annual checkup, or to have some seemingly minor bump, rash or pain properly evaluated. Easier to just suck it up and drive on, so to speak. But, with this attitude, health problems, such as cancer or heart disease can get steadily worse. By the time a man finally seeks help, the problem is much more difficult to treat.
