4 Your Health: who a dog bites; exercising before surgery; severity of scars

Posted: Updated:

Doctors and patients often disagree on how scars look after surgery.

Researchers at the University of Pennsylvania asked over 4,000 patients and their surgeons to assess the severity of their scars. They disagreed in their evaluations 28 percent of the time. Patients were more likely to focus on the depth of the scar while doctors tended to emphasize color and texture.

Experts say these findings may help surgeons set better expectations for their patients before their procedure. 

Benefits of exercising before surgery

Patients facing surgery for lung cancer may want to get on their feet and get active.

That's because a new Australian study found regular exercise before lung surgery cut the risk of complications afterwards by half. A pre-surgery exercise program also reduced their hospital stay by nearly three days.

Personality my prompt a dog to bite

Your personality could put you at risk of being bitten by a dog. A British study of nearly 700 people found those with an nervous disposition were more likely to be nipped.

In fact, people who were the most anxious had a 23 percent higher risk of getting bitten by a dog than those who were the least neurotic. The study also found dog owners were three times more likely to be bitten than non-dog owners.

But more than half of bite victims said they had been nipped by a dog they did not know.
