ORLANDO, Fla. - When it comes to health checkups, men are notorious procrastinators.

The Centers for Disease Control and Prevention reports men are 33% less likely than women to have visited a doctor in the past year, and those who do go are less apt to be honest about their symptoms and history, but there are some problems men should get checked out.

The first: erectile dysfunction. It could be a risk factor for a heart attack or stroke. Heart disease accounts for one in every four deaths in men. Jaw or neck pain are also signs of a heart attack.

Trouble urinating is another issue to take seriously. It could be a symptom of prostate cancer.

"Death from prostate cancer is at an all-time high, 29,000 deaths a year in the U.S." said Dr. Daniel George, a professor of medicine and surgery at Duke Cancer Institute.

Other signs include blood in the urine or semen.

Men should also see a doctor if they have sleep issues. These problems may indicate depression or sleep apnea.

Chronic itching is another symptom not to ignore. It could signal lymphoma, multiple myeloma, or even diabetes.

Also pay attention if you have trouble swallowing. It might be acid reflux, which can lead to esophageal cancer, a disease that's more common in men.

Want the man in your life to get that health checkup? Keep asking him to go. At least 20% of men admit to going to the doctor just so a loved one will stop bothering them about it.
