13th annual Alex's Lemonade Stand at CHOP

WEST PHILADELPHIA (WPVI) -- The Children's Hospital of Philadelphia is kicking off another fundraiser to benefit pediatric cancer research.

Friday marked the start of the 13th annual Alex's Lemonade Stand at CHOP.

The foundation was started by a young girl who lost her battle with cancer in 2004.

Since then it has raised more than 120 Million dollars.

This year CHOP will host 29 lemonade stands at the hospital and its satellite offices.
