Jaime Pressly revealed that after giving birth to her son Dezi in 2007, she suffered mastitis.
"I had something that happened to me years ago, I didn't know," she said on "The Talk" on Wednesday. "I have a high threshold for pain, I was a dancer for 25 years. When I had my son, I got mastitis but I didn't know, cause I thought it was just regular breast feeding pain."
According to the Mayo Clinic, mastitis is an infection of the breast tissue, and treatment usually includes antibiotics. For the actress, she ended up almost having a full mastectomy because it spread and mutated.
She said four years after having her son, she noticed lumps all over her breasts.
"What do you immediately think of?" she said, alluding to breast cancer.
Pressly said she went to the doctor and had the scar tissue removed, but then it spread.
"I still have some breast tissue left, but almost a full mastectomy," she said of her procedures.
She even said the mastitis mutated into something else and it was a big ordeal.
"[But] thank God it wasn't [cancer]," she said knocking on the wood table.
A mastitis infection warranting a mastectomy would be extremely rare, said Dr. Jennifer Ashton, a practicing OBGYN and senior medical contributor for ABC News. Mastitis is typically treated with antibiotics and warm compresses, she said.
“While mastitis is painful, upsetting and potentially can lead to a systemic blood infection, it can usually be effectively treated and breast feeding can continue,” Ashton said.
