Rob Ford has cancer, Toronto mayor's doctor says

TORONTO -- Toronto Mayor Rob Ford's doctor says the mayor has cancer.

Dr. Zane Cohen, a colorectal surgeon at Mount Sinai hospital, said Wednesday Ford has a malignant sarcoma tumor which he described as "very rare" and "very difficult."

Ford has been hospitalized for a week with a tumor in his abdomen.

The mayor withdrew his re-election bid Friday as he undergoes treatment, dramatically ending a campaign he had doggedly pursued despite a stint in rehab and calls for him to quit amid drug and alcohol scandals.

Doug Ford is running for mayor in his brother's place.
