Doctor to provide medical update on Toronto mayor Rob Ford's tumor on Wednesday

The brother of controversial Toronto Mayor Rob Ford says a doctor will provide a medical update on Ford's health on Wednesday.

The mayor has been hospitalized since last Wednesday with a tumor in his abdomen. Biopsy results were expected to take a week.

Ford, 45, withdrew his re-election bid Friday as he seeks treatment for the tumor, dramatically ending a campaign he had doggedly pursued despite a stint in rehab and calls for him to quit amid drug and alcohol scandals.

Ford's brother, city councilor Doug Ford, said a doctor will provide an update Wednesday at about 5 PM local time. Doug Ford says his brother is having a "tough go" of it and he says it is "heart wrenching."

Doug Ford is running for mayor in Rob's place.
