Toronto Mayor Rob Ford says tumour not shrinking, needs more chemotherapy

TORONTO - Toronto Mayor Rob Ford says a cancerous tumour in his abdomen has not shrunk after two rounds of chemotherapy, and he will need another round.

Ford tells the Toronto Sun he will start the new treatments on Monday.

On top of that, the mayor says he has pneumonia and is taking "a heavy dose" of antibiotics.

Doctors discovered a rare and aggressive cancer in Ford’s abdomen in September and were hoping chemotherapy would shrink the tumour so they could operate.

The mayor says while the tumour has not become any smaller, it has not increased in size either.

Ford will remain mayor until Dec. 2, when John Tory takes over after winning last week’s mayoral election.

Ford won election as a councillor after dropping out of the mayoral race following his cancer diagnosis.
