The former My Wife and Kids star was diagnosed with sarcoidosis, which causes inflammation in the lymph nodes, a few years ago, but a recent article in the National Enquirer suggested her condition was deteriorating and she was dying.
However, the 42-year-old wife of actor Duane Martin has dismissed the allegations and insists she has the illness under control.
In a statement issued to People magazine, Campbell-Martin says, "Thank you, everyone, for your concern. However, no worry is needed.
"I was diagnosed with a lung disorder that some people walk around with and don’t even know they have. Through early diagnosis I'm happy to share that I stay healthy with diet and exercise."
