TORONTO -- Rob Ford faces months of recovery following successful surgery at a Toronto hospital to remove a tumour from his abdomen.

The former Toronto mayor's chief of staff says Ford was under anesthesia for about 10 hours but was conscious and visiting with his family on Monday night.

Dan Jacobs says doctors found no new growths and were able to remove all existing growths.

Jacobs says Ford, now a city councillor, is in "some pain," and doctors have told him he will need to "take it especially easy" for up to three months.

Ford's surgery followed several rounds of chemotherapy and radiation which he said had reduced his tumour to an operable size.

Ford abandoned his mayoral re-election bid last September then won a council seat instead after doctors discovered his rare, aggressive malignant liposarcoma.
