Jillian Cardarelli Shares the Unusual Warning Sign She Spotted Before Her Breast Cancer Diagnosis

The 34-year-old is set to make her Grand Ole Opry debut in honor of Breast Cancer Awareness Month.

Something felt off this time. Earlier this year, Cardarelli noticed the same density in her right breast that she and her doctors had been monitoring since her late 20s. But now it was painful during her period, the lump seemed to have shifted, and its shape felt different. “It was thicker,” she told TODAY.com.

Then came the exhaustion. During a photoshoot, the country singer only had enough energy for three of the five outfits she was scheduled to wear. “I was like, ‘I need to go home and take a nap,’ which is not very like me at all,” Cardarelli says. “I’m usually, you know, the Energizer Bunny.” She assumed she was simply worn out from traveling and performing, all while telling herself that cancer usually doesn’t hurt.

In her case, it did.

“For peace of mind, I decided to go just get it checked out yet again,” Cardarelli says. “They’re probably just going to pat me on the back and tell me all is good, like they always do. And it just wasn’t the case that time.”

After an ultrasound, a 3D mammogram and a biopsy in May 2026, the Nashville-based artist was diagnosed with stage 2 invasive ductal carcinoma at 33.

Survival Mode

When Cardarelli received the diagnosis, her mother was with her. She later told her husband by phone, and then her mindset shifted.

“I’m a very action-oriented person, so I was like, ‘OK, what are we going to do to fix this? What is my next action step here?’” she says.

Like any other challenge in her life, she was determined to tackle it head-on.

Her doctors at Boston’s Dana-Farber Cancer Institute chose the treatment path they believed would help most in the shortest amount of time. That plan included surgery — a lumpectomy to remove the mass and a sentinel lymph node biopsy to check whether the cancer had spread — followed by 19 rounds of radiation in August.

Between procedures and treatments, Cardarelli made space for life to continue.

“I tried my best to maintain normalcy as much as I could in my life,” she recalls. “So, after I was diagnosed, I flew back to Nashville from Boston while we waited for the biopsy results and all that, and I was in the studio recording a new song.”

She then returned to Boston for surgery before flying to Canada to film Season 2 of “Crossroad Springs,” the drama she stars in on Great American Family.

“That really helped me feel like me ... like I am not this cancer diagnosis,” she says. “I’m Jillian, who is going through a really, really hard time ... but I’m still me, right? And I think that really helped me maintain a good perspective through this whole thing.”

After that, she and her husband went back to Boston for four weeks of radiation, which she underwent five days a week. Elvis Presley, her “favorite artist of all time,” was a constant presence in her hospital playlist.

Cardarelli handled treatment well enough that she was still able to keep up with her favorite barre classes. “I’d go there after treatment. Some days it was harder than others, and your body does feel different, but I found pushing myself to do the things that made me me, and made me feel good, it really helped.”

The Next Stage

The diagnosis came as a surprise. Cardarelli says she has always worked out five days a week and eaten nutrient-dense meals. “I tested negative for all the genetic markers” linked to breast cancer, she says. The only family history was her mother’s colon cancer.

Still, she has learned that cancer does not discriminate and affects many people without inherited gene mutations. Thankfully, she is now cancer-free.

Her health remains her top priority, but the experience has given her a new perspective. “I’m focusing on protein, especially with the regimen that I’m on now. Bone density is something that I need to keep an eye on,” Cardarelli says. The medication she will take for the next few years to block the hormones that fueled her cancer cells can increase the risk of bone loss.

She is also putting more emphasis on strength training alongside her barre routine.

Her next milestone is on the music side of her life. Cardarelli will make her Grand Ole Opry debut in Nashville for the 18th Annual Opry Goes Pink in collaboration with the Susan G. Komen breast cancer foundation.

Andrea Canning, NBC Dateline correspondent and Cardarelli’s friend, will introduce her onstage.

“I don’t remember a time when this wasn’t my dream,” Cardarelli says of performing at the historic venue. She adds that sharing the moment with such an important friend makes it even more meaningful. “So, it’s just a really beautiful way to cap out a not-so-great year for me, health-wise. It just goes to show that even through the darkest storms, there will be a light at the end of the tunnel.”

One of the songs she will perform is “Happily Even After.”

“I wrote it long before I had cancer,” Cardarelli says. “No matter what, life has its challenges, and no matter what season you’re in, whether it’s grief, illness, loss, or just a tough season, we sometimes don’t get the happily ever after that we picture in our heads, but we can have a happily even after.”

“So, I’m really excited to sing that on the Opry stage,” she says. “Hopefully it’ll bring hope to anybody going through any kind of hard time, not just a cancer diagnosis.”
