Georgia O'Connor cause of death: How did the 25-year-old British boxing star die?

Georgia O’Connor, a promising British boxer, tragically passed away on May 22. She was known for her undefeated record in professional boxing and her remarkable achievements in amateur sports. Georgia’s death was confirmed by Boxxer.

“My heart goes out to Georgia’s parents and partner, who I know did everything they could tirelessly and are going through so much right now,” Boxxer CEO Ben Shalom said.


Georgia was only 25.


Struggle with health issues:
Georgia O'Connor has died following a battle with cancer. The 25-year-old repeatedly claimed she was overlooked by doctors for months.

In early 2025, O’Connor was diagnosed with a rare and aggressive form of cancer, a condition that rapidly progressed despite her previous health challenges.

Earlier in her life, she had battled ulcerative colitis , a chronic inflammatory bowel disease, which she openly discussed to raise awareness. Her diagnosis came after a prolonged period of misdiagnosis and delayed treatment, during which she experienced severe symptoms and sought medical attention multiple times. In a social media post, O’Connor had expressed her frustration with the healthcare system, recalling how her concerns were initially dismissed by medical professionals.



“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,” she had written in a post dated 31 January.

She added, “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.”

Georgia continued, “But not one doctor f**k**g listened to me. Not one doctor took me seriously. Not one doctor did the scans or blood tests I begged for whilst crying on the floor in agony… They gaslit me, told me it was nothing… One even told me that it’s ‘all in my head.’ And now? Now the cancer has spread.”


What cancer was Georgia suffering from?

Although Georgia was pretty open about her health struggles and her cancer journey, she did not disclose what cancer she was suffering from. The 25-year-old only had mentioned that her cancer was “incurable.”

On top of that, Georgia had shared the news of her pregnancy and the miscarriage as well.


Despite her struggles, the British boxing star tried to stay hopeful.

She had shared in a post in February, “The last few months have been a rollercoaster. 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!”

She married her partner, Adriano Cardinali, on May 9, calling it “the best day of my life,” even as her health rapidly declined. Only two weeks after her wedding, she passed away.
