PITTSBURGH - The head of a prominent cancer research institute issued an unprecedented warning to his faculty and staff Wednesday: Limit cell phone use because of the possible risk of cancer.

The warning from Dr. Ronald B. Herberman, director of the University of Pittsburgh Cancer Institute, is contrary to numerous studies that don't find a link between cancer and cell phone use, and a public lack of worry by the U.S. Food and Drug Administration.

Herberman is basing his alarm on early unpublished data. He says it takes too long to get answers from science and he believes people should take action now — especially when it comes to children.

"Really at the heart of my concern is that we shouldn't wait for a definitive study to come out, but err on the side of being safe rather than sorry later," Herberman said.

Newswise - It may be the most wonderful time of the year, but recent toy recalls are putting a damper on the joyful holiday shopping season.

As parents begin perusing toy stores with lists in hand, many worry about picking goodies that are safe for their little ones.

"I am very concerned about what toys to buy," says Linda Mata, who is buying toys for her grandchildren. "You may buy them now, and then find out later that there is a recall after the children have already played with them."

Jolene Duckworth, a mother of two, is also being extra cautious this holiday season: "It is very important to know what types of toys are safe. The recent recalls due to lead have made me very worried about what to buy."
