British professional boxer Georgia O’Connor has died aged 25, her promotion company BOXXER said on Thursday.

“We are heartbroken by the passing of Georgia O’Connor,” BOXXER said in a statement on X. “A true warrior inside and outside the ring, the boxing community has lost a talented, courageous and determined young woman far too soon.”

O’Connor’s death comes months after the British boxer shared with fans that she was suffering from cancer.

“For 17 weeks since the start of October, I’ve been in constant pain, going back and forth between Durham and Newcastle RVI A&E knowing deep down something was seriously wrong,” O’Connor wrote. “I said from the start I felt it was cancer. I KNEW the risks. I have colitis and PSC, two diseases that dramatically increase the chances of getting it. I KNOW how high my risk is and they do too. They always did.”

O’Connor, who was from Durham, England, did not share what type of cancer she was suffering from.

In the same January Instagram post, she also accused doctors of taking her concerns seriously.

“Not one doctor did the scans or blood tests I begged for whilst crying on the floor in agony.Instead, they dismissed me. They gaslit me, told me it was nothing, made me feel like I was overreacting,” she wrote. “They refused to scan me. They refused to investigate. They REFUSED to listen.”

In February, the 25 year old also shared on Instagram that she suffered from a miscarriage.

“The last few months have been a rollercoaster,” O’Connor wrote. “I’ve been pregnant with a beautiful baby, suffered a miscarriage, then got diagnosed with ‘incurable’ cancer. But I still feel on top of the world!”

Last week, the boxer shared with 40,000 Instagram followers that she got married earlier this month. She posted an image of her holding her husband’s hand and wrote: “09.05.2025. The day I married the love of my life.”

In a separate Instagram post from February, O’Connor said that her then-boyfriend quit his job to support her through cancer.
