Rash led to breast cancer diagnosis for 'fit and well' Irish mum at 41

Juliette O'Connell was diagnosed with breast cancer at age 41 and underwent surgery and radiotherapy, though she has since recovered and remains cancer-free.
I never thought for one minute this could be breast cancer
O'Connell describes her mindset when the rash first appeared, fit and healthy with no family history of the disease.

What made you finally go to the doctor if you weren't worried about the rash?

Mimi

Honestly, it was pure practicality. My son was sick, and I was paying for his appointment anyway. I thought, why not mention it while I'm there? I wasn't thinking of it as urgent.

Mark

And the doctor wasn't concerned either?

Mimi

No, she wasn't. She referred me, but her lack of alarm meant I didn't feel alarmed. That's the thing—when you're fit, when you feel well, it's easy to believe that nothing serious could be wrong.

Mark

But then the nipple pain started.

Mimi

Yes, and I didn't connect it to anything. I just tried to manage it myself. I didn't realize it was a symptom. I think if I'd known then what I know now, I would have pushed harder, asked more questions.

Mark

Ten months from first noticing the rash to diagnosis. That's a long time.

Mimi

It is. And I was lucky. The cancer was caught, treated, and I've been well ever since. But I think about how many people might be ignoring similar signs right now, thinking like I did.

Mark

Is that why you do this work now?

Mimi

Absolutely. I want people to know that breast cancer doesn't announce itself the way we think it will. It doesn't always come with the symptoms we've been told to expect. A rash, pain, anything unusual—that matters. That deserves attention.

  • A persistent rash on her collarbone and breast went unexamined for months because Juliette O'Connell felt too fit and healthy to believe anything could be seriously wrong.
  • She only mentioned the rash to a doctor by chance — tagging her concern onto her son's appointment as an afterthought, reasoning she might as well get two opinions for the cost of one visit.
  • A new symptom, nipple pain that worsened over weeks, went unspoken and untreated at home with Sudocrem, because she didn't know it could signal cancer.
  • Ten months after the rash first appeared, a mammogram delivered the diagnosis: breast cancer, requiring surgery and radiotherapy before she was finally declared cancer-free.
  • Now in her late fifties, O'Connell channels her near-miss into advocacy as a Patient Ambassador for Breast Cancer Ireland's Very Pink Run, urging others not to wait the way she did.

In the spring of 2012, a 41-year-old Irish woman named Juliette O'Connell received a breast cancer diagnosis that had been quietly announcing itself for nearly a year — first as a rash she dismissed, then as a pain she didn't recognise as a warning. Her story is a reminder that the body speaks in unfamiliar languages, and that good health and active living offer no immunity from illness, only perhaps a false sense of safety. More than a decade cancer-free, she now turns her experience outward, working to ensure others hear what she almost missed.

Juliette O'Connell was 41, cycling regularly and training for events, when a rash appeared across her collarbone and left breast. She felt too well to worry. Months passed before she mentioned it to a doctor — almost by accident, during a visit she'd made for her son. The doctor wasn't alarmed, a referral letter arrived, and she went home thinking little of it.

By December, something new had begun. Her left nipple started to hurt, the pain deepening over weeks. She tried Sudocrem. She told no one. She didn't know that nipple pain could be a sign of cancer, and she was too busy living her life to connect it to the rash. When the mammogram appointment finally came through, it was March 2012 — ten months after she first noticed something was wrong. The diagnosis was breast cancer. Surgery and radiotherapy followed, and they worked. She has been cancer-free ever since.

More than a decade on, O'Connell has made her experience the foundation of her public life. She works as an outreach coordinator for Breast Cancer Ireland in Munster and serves as a Patient Ambassador for the Very Pink Run, a fundraising campaign held across Dublin, Kilkenny, and Cork each autumn. Her message is direct: fitness, youth, and a clean family history are not protection. A rash that lingers, a pain that grows — these deserve a doctor's attention, not a wait-and-see. Her decade of good health is proof that early detection saves lives. It also nearly didn't happen at all.

Juliette O'Connell was 41 years old and felt as fit as she'd ever been. She cycled regularly, trained for events, had no family history of cancer, and carried none of the weight loss or fatigue that people associate with serious illness. Then she noticed a rash spreading across her collarbone and left breast.

She didn't rush to a doctor. Months passed. The rash remained, but she remained unconvinced it meant anything urgent. It wasn't until October, when her son fell ill and she took him to a medical appointment, that she decided to mention it to the doctor as well. The appointment cost fifty euros; she figured she might as well get two opinions for the price of one. The doctor wasn't alarmed, and neither was Juliette. She showed the rash, received a referral letter to the breast care unit in Limerick, and went home thinking little of it.

By the time she got an appointment at the breast care unit in December, something else had begun. Her left nipple started to hurt. The pain grew worse over the following weeks. She tried Sudocrem, hoping to soothe it away, but nothing worked. She didn't tell anyone about it. She didn't know that a sore nipple could be a warning sign of cancer. She was too busy being fit and well, too busy with her life to connect the dots.

The mammogram appointment came through in the post. On March 9th, 2012—ten months after she first noticed the rash—she received her diagnosis. Breast cancer. She underwent surgery and radiotherapy. The treatment was brutal in its own way, but it worked. She became cancer-free and has remained so for more than a decade.

Now in her late fifties, O'Connell has channeled that experience into advocacy. She works as an outreach coordinator for Breast Cancer Ireland in the Munster region, and she's taken on a role as a Patient Ambassador for the organization's Very Pink Run, an annual fundraising campaign that runs from late August into early September. The run features events across Dublin, Kilkenny, and Cork, welcoming everyone from casual walkers to serious runners, across distances of five or ten kilometers.

Her message is simple and urgent: be breast aware. Don't assume that because you feel healthy, because you exercise, because you have no family history, that something unusual can't be serious. A rash that doesn't fade. A pain that intensifies. These are not things to ignore or treat at home. They are things to bring to a doctor, to have checked, to take seriously. O'Connell's decade of good health since her diagnosis is a testament to early detection and treatment—but it almost didn't happen because she waited months to act on what her body was telling her.

I was fit, healthy and well, enjoying my cycling and training for different events. I never thought for one minute that this could be breast cancer.
