Olivia Newton-John has been cancer-free since 1993 -- and now the singer/actress is revealing a new weapon in the war against breast cancer.

The "Grease" star is teaming up with Curves to give out one million Liv Aid Breast Self-Exam Kits. The kits include a gel-filled pouch that magnifies the feel of a lump -- and could allow women to detect any suspicious tumors early, working on something as small as a grain of sugar. "It's for women to do self breast examinations on regular basis," Olivia explains.

Early detection was key for Newton-John when she was diagnosed with breast cancer -- and she wants to help other women be as fortunate as she was by detecting the disease early. "I feel very lucky to be here and be able to do this," Olivia reveals.
