Christopher Reeve's widow DANA REEVE is devastated after being diagnosed with lung cancer.

Dana, who has never smoked, was heartbroken after the Superman actor's death in October last year (04), but his long fight against his spinal injuries following a horse riding accident, is inspiring her determination to beat the disease.

The 43-year-old actress says, "I have recently been diagnosed with lung cancer, and am currently undergoing treatment. I have an excellent team of physicians, and we are optimistic about my prognosis.

"Now, more than ever, I feel Chris with me as I face this challenge. As always, I look to him as the ultimate example of defying the odds with strength, courage and hope in the face of life's adversities."

The couple have a 13-year-old son WILL.
