To remove any effects of the risk information not corresponding to descriptions the original data was recoded.

About 79 percent of respondents said they recalled risk information from drug commercials on television, up 3 percentage points from the year before.

All risk information is based only on discovered genetic factors.

Electronic communication and computers changed the gathering of commercial risk information.

It is generally accepted that communication about genetic risk information within families is largely the responsibility of family members themselves.

Television commercials may also have to change how they discuss risk information, officials said.

These factors influence the processing of risk information and subsequent health behaviors.

A positive family history may sometimes provide risk information in the absence of a specific genetically determined cancer syndrome.

Studies have shown that the brain has systematic faults in reasoning, especially when processing risk information like this.

"We just need to communicate the risk information with balance and proportion."
