( CNN ) -- Toronto Mayor Rob Ford now has a new fight on his hands : a tumor . The president of Humber River Hospital announced Wednesday that the embattled mayor -- just over two months removed from treatment for substance abuse -- has been admitted to the hospital , where doctors will try to get `` a definitive diagnosis . '' `` It is being investigated further and we need to determine exactly what type of tumor it is , and then we can decide on what type of treatment is required , '' said Dr. Rueben Devlin , the Toronto hospital 's president . According to Devlin , Ford has been `` complaining of abdominal pains '' for over three months that got worse over the last 24 hours . That prompted the mayor to go the hospital , where a CT scan revealed the tumor in his abdomen . It 's not known yet if the tumor is malignant , according to Devlin . Doug Ford , the mayor 's brother and a Toronto city councilor , asked reporters `` just to give our family a day or so '' as they learn more about the situation and determine what to do next -- including deciding whether or not Rob Ford will continue his campaign for re-election . `` Rob is in good spirits , and I just want to thank the well-wishers for all the calls that are coming in , '' Doug Ford said . The health ailment adds to the list of struggles facing Ford , whose fall from grace began in May 2013 with the release of a cell phone video that appeared to show him smoking crack cocaine . The Toronto city council largely stripped him of his mayoral powers months later over those and other allegations of bad behavior . Ford did n't back down , though , instead vowing `` outright war '' on the city council . The mayor apologized for `` a lot of stupid things , '' including having used crack cocaine , but he refused to resign or enter rehab . In fact , despite all the criticism and his becoming a punchline for jokes in Canada as well as the United States , Ford launched a bid for re-election . Yet this past spring , after a local newspaper reported on a new video that allegedly shows him smoking crack cocaine , Ford relented on one front : by going into rehab . He returned to work in late June , after a two-month rehab stint , saying he was `` ashamed , embarrassed and humiliated '' by some of his past actions . But even then , he refused to resign or refrain from campaigning , saying to the voters of Toronto , `` I look forward to serving you for many , many more years . '' 'Ashamed , embarrassed ' Rob Ford returns as Toronto mayor after rehab .
