Actress Jaime Pressly has cleared up reports she had a full mastectomy after developing mastitis while breastfeeding her baby son in 2007.

The Joe Dirt star opened up about her health crisis during a recent appearance on U.S. Tv chat show The Talk, revealing she had no idea that anything was wrong until lumps started appearing on her breasts in 2011.

She explained, "I have a high threshold for pain, I was a dancer for 25 years and when I had my son I got mastitis. I didn't know because I thought it was regular breastfeeding pain, and four years later I had lumps (all over my breasts).

"(I) went to the doctor, he took the scar tissue out of (one breast) and then six months later, because when you open it up it spreads, I had to go back and do (the other breast). Then, I had another doctor and they had to do almost a full mastectomy.

"I still have some breast tissue left, just from the mastitis because it mutated into something else because it sat dormant for a while. It was the craziest thing. Thank God it wasn't (cancer)."

But Pressly fears her big reveal may have been a little too dramatic and now she's playing down the crisis.

In a new chat with news show Extra, she explains, "I went in for surgery to remove scar tissue, and some like lumps were basically caused by bacteria I got during breast feeding, like a mastitis. Once the doctor got inside he realised it was in more areas than he thought, and two-and-a-half hours turned into seven-and-a-half hours of surgery... To put all the rumours to rest, I am fine."
