Healthcast: Toddlers who watch TV at risk for bullying

Toddlers who watch too much television may struggle socially by middle school. 

A new study looked into the viewing habits of about 2,000 Canadian children. 

The study found that children around 2 and a half years old have an 11-percent risk of being bullied in sixth grade for every hour they watch television. 

According to researchers, too much screen time means less time for family interactions and social play. 

Also in Healthcast, lung cancer patients are living longer if they are able to quit smoking when they are diagnosed. 

Researchers at a cancer institute in Buffalo examined data on 250 lung cancer patients who were also smokers. 

According to experts, those who quit smoking lived an average of 28 months, while remaining smokers lived an average of 18 months.
