Peloton’s Leanne Hainsby has revealed she has been battling breast cancer since August.

The fitness instructor shared the news on social media on Friday, describing the treatments she has received after one doctor dismissed the lump she discovered. The 35-year-old revealed that she’s been through 12 weeks of chemotherapy and will begin radiation soon.

“Two days before my best friend’s funeral, I found a lump in my breast,” she began. “After multiple scans and appointments with both consultants and cancer nurses, and being completely terrified for a few weeks, in August 2022, I was diagnosed with breast cancer.”

Hainsby said that she “continued to show up as ‘normal’” but the reality was very different most of the time and how her classes gave her a “focus” and “sparkle: during “incredibly rough times.”

She continued, “I would teach my Wednesday morning LIVE classes, and then meet my Mum and go to the treatment suite for my weekly dose (alongside other drugs as part of my treatment plan). Chemo is no joke. Cold caps are no joke.”

The British fitness sensation also revealed that she has had her surgery, will have her porta cath surgically removed, and had “given time of chemotherapy to do a round of IVF.”

“Treatment will continue for a long time for me, hospital visits are the norm, and I focus on one step at a time. I do feel very fortunate to be having my treatment privately. The nurses and doctors are incredible, and I wouldn’t be here without them,” she admitted.

The post also featured herself dressed in the aforementioned cold caps which was also targeted to raise awareness of breast cancer.

“To raise awareness. I’m young for breast cancer at 35. I went to a doctor the same morning I found the lump, and I was told everything was ok. I trusted my gut and got a second opinion. That saved my life. Check, and check again.”

Leanne Hainsby, who is currently engaged to fellow Peloton instructor Ben Alldis, concluded her post with good news.

“I’m nearly 6 months down the line. I’m in fantastic hands, and I’ve got this. Nobody wants to be sat in a room and told they have cancer, and yet I’ve always felt like one of the lucky ones. I am one of the lucky ones. Lucky to be diagnosed early, lucky to be moving fast through treatment, lucky to know I WILL BE OK. Your life outlook becomes so very different in times like this.”
