Apparently she did suffer from it but came back to place 3rd in the Toronto Pro Show last June
"Third place went to Mah-Ann Mendoza who could quite easily be considered a sentimental favorite with the understanding that she had faced a battle with cancer recently. A veteran competitor who first took to the competitive stage in 1990 as a seventh-place lightweight finisher at the NPC Western Oregon, Mendoza rose to the pro level after winning the overall NPC USA title in 2001. She’s been a pro ever since having competed in five Ms. Internationals and four Ms.O’s. Along the way she was also an overall winner at the 2007 Europa Super Show. Her conditioning level at this event was nothing short of miraculous considering the challenges she faced. It could be said that she easily equaled the best she’s ever been in her long competitive career – and only guts, conviction, desire, faith and a strong allegiance to her self-worth made that possible. The $1,000 in prize money for her third-place finish is miniscule in the bigger picture.
But more importantly, hats off to you Mah-Ann, and big ups to a 52-year-old female bodybuilder anyone can greatly admire…and is now qualified for another trip to the Ms. Olympia."
