Ryan stands up to cancer

Ryan Seacrest lost three of his grandparents to cancer

Ryan took part in the Stand Up To Cancer broadcast last night. Cancer is something that affects all of us, either directly or through close friends and relatives — almost half of us will be diagnosed with cancer at some time in our lives — so Ryan’s contribution to raising awareness and funding for research through charity events like this and his radio show is really important.
