Birmingham chairman David Gold believes the qualities demonstrated by Karren Brady which earned her the title of the 'first lady of football' will help in the battle to overcome aneurysm of the brain.
Blues managing director Brady is to undergo surgery on Monday which is expected to keep her away from her desk at St Andrews for a month.
Brady showed great determination and resolve in fighting her way to the top in the male-dominated footballing world in more than a decade with City and Gold is confident such resolve will stand her in good stead now.
Gold told PA Sport: 'We are all shocked to hear Karren has to have an operation but she is the first lady of football and you don't achieve that without being strong, determined and resolute.
'That's what made her what she is, not because of the fact that she is pretty or attractive.
'She has got those qualities of being strong, determined and resolute and they will stand her in good stead during this adversity. I can't sum it up better than that.
'After the operation, Karren will have a period of recuperation but it wouldn't surprise me, knowing Karren the way I do, that she will be back at her desk in a couple of weeks.'
Birmingham issued a statement which read: 'We can confirm that the club's managing director, Karren Brady, is to undergo treatment for an aneurysm in the brain, which was diagnosed on Wednesday.
'The condition has been caught early and Karren is expected to have a surgical procedure early next week. Karren anticipates being absent from her duties at Birmingham City for approximately one month.
'Commercial director Perry Deakin and financial director Roger Bannister will jointly assume her responsibilities in her absence.'
The 36-year-old herself said: 'Obviously this has come as a big shock to me and my family but I am in very capable hands and diagnosing the condition this early is very encouraging.
'I would like to thank everybody for their messages of support and I plan to be back at work as soon as I possibly can.'
