Dana Reeve has cancer

She was by her husband's side as he dealt with his paralysis during the last nine years of his life.

And now, Dana Reeve -- the widow of actor Christopher Reeve -- is facing a health crisis of her own. She says she has lung cancer.

Reeve says she's being treated by "an excellent team of physicians."

She says, "Now, more than ever, I feel Christopher with me as I face this challenge." She says he was the "ultimate example of defying the odds."

Reeve is the chairwoman of the Christopher Reeve Paralysis Foundation. It funds research on paralysis.
