The Loose Woman panellist admitted she'd been scared about the lump but decided to postpone seeing a doctor until she had completed her time in the house.
Speaking on today's show, she said: "I had a lump a few years ago, but… only a few weeks ago, which I've never told anybody, I found another one. It was me who found it, I didn't tell anybody, I went to hospital but I was going into the Big Brother house and I didn't want to say anything because obviously I'm working and I have to earn, I'm the only bread winner in the family.
"And stupidly, and please don't ever do this, anybody, don't not tell somebody. I went in, frightened, and came out, I went back to hospital, fortunately it was only a cyst.'
She went on to say: "All I'm saying is, my fear was A) I didn't want to know, and B) I didn't want to tell anybody. And I think, really, if you look at everybody in a street, they would tell you that was one of the biggest problems, is terror, is not being able to look, touch, feel, and go 'It could be me, well actually I'll put my head in the sand and I'll pretend it's not me'…and I think that's what happened to me.
"It was the most stupid thing I have ever done in my life. So if anybody's listening, please don't do what I did."
