Mayor Rob Ford to start 2nd round of chemotherapy Tuesday
Tumour found in mayor's abdomen last month, Ford later diagnosed with liposarcoma
Rob Ford's brother says the ailing Toronto mayor will begin a second round of chemotherapy on Tuesday.
Doug Ford says he will back in hospital then for the cancer treatment.
A pale and tired-looking Ford told reporters at city hall on Thursday that doctors have told him there's a 50/50 survival rate for the rare and aggressive cancer in his body.
Ford underwent an initial round of chemotherapy last month after doctors found a tumour in his abdomen, and said the treatment "knocked the you-know-what" out of him but that he remains optimistic.
The diagnosis prompted Ford to end his re-election bid, opting for a run for council while his brother Doug is now a candidate for the city's top job.
Ford also said fighting cancer has been his biggest challenge in a year plagued with scandal, including his admitted drug use and a stint in rehab for substance abuse.
