TORONTO -- Former Toronto mayor Rob Ford says his radiation treatments for a rare form of abdominal cancer are ending Thursday and he will know soon if doctors can operate.

Ford received chemotherapy and radiation for the tumour that was discovered last September, prompting him to abandon his bid for re-election as mayor.

He ran for his old council seat instead, and won in the Oct. 27 municipal vote.

Ford says he plans to take a trip with his family before doctors take the next step.

The former mayor says when he returns, doctors will perform an MRI that will determine if the tumour is small enough to operate.

He says if it is small enough, doctors would operate at the end of April of the beginning of May.

"If it's not small enough, then that's not good news," Ford said.

"So we'll just take one step and a time."
