Rach is getting emotional as she shifts gears to talk about a serious subject -- cancer. She's sharing her #Reasons2StandUp ahead of tonight's Stand Up To Cancer telecast. One of Rach's reasons to stand up stems from her love of cooking -- cancer inevitably takes loved ones away from the dining table.
Listen to what Rach and many, many other stars had to say below. Share your reason on social media using the hashtag #Reasons2StandUp and tune in to Stand Up 2 Cancer Friday at 8/7c on ABC, CBS, FOX and NBC.
