A notorious conspiracy theorist who allegedly coerced her dying daughter into refusing cancer treatment has fired back furiously at her sons’ claims that she is responsible for her death.
Kate Shemirani, who rose to notoriety with rabid anti-vax rants in which she branded Covid vaccines as Satanic, has denied that daughter Paloma Shemirani was ever diagnosed with the blood cancer that killed her at the age of 23 in July last year.
Paloma’s brothers Gabriel and Sebastian explosively claimed earlier this week that their sister had been indoctrinated into refusing professional medical help for her non-Hodgkin lymphoma by their mother.
The Cambridge graduate and beauty queen ultimately suffered a rapid deterioration in her health in just seven months and suffered a heart attack a week before she died.
Friends of Paloma had also claimed earlier this week that Kate had sought to cut her daughter off from society as her condition worsened – even as Paloma texted her boyfriend Ander Harris to claim that she was being ‘abused’ by her mother.
But Ms Shemirani – who still calls herself a ‘nurse’ despite being banned from nursing for sharing misinformation online – has hit back at the claims online.
In a post on X, she claims her daughter was ‘gaslit’ by doctors and has even suggested she was experimented on by medics, accusing doctors of breaching the Nuremberg Code drawn up in 1947 to control the safety of medical experiments.

Straight-A student Paloma Shemirani died of cancer last year – coerced, her brothers believe, into refusing mainstream cancer treatment

Paloma’s mother is the notorious conspiracy theorist and anti-vaxxer Kate Shemirani (the pair pictured together)

Sebastian Shemirani (pictured in 2020) believes his mother’s refusal to believe in proven conventional medical treatments contributed to his sister’s death
She wrote: ‘Our daughter died following a chain of gross medical failings, breaches of consent law, falsified medical records, and reckless emergency drug use that violated every protocol for her age, weight, and clinical presentation.
‘Paloma was never “coerced.” She was never “radicalised”. She was a woman of conviction and clarity.
‘We will not allow our daughter’s memory to be defamed, nor her death to be sanitised.’
Kate – who brands herself the ‘Natural Nurse’ – rose to notoriety during the pandemic as she began sharing vaccine misinformation on what was then Twitter, for which she was kicked off the social network.
She was allowed to return after it rebranded as X under Elon Musk. She is believed to have worked briefly for the NHS in the 1980s before working as a BA air hostess and model before administering Botox, fillers and peels while bringing up her children.
Paloma was diagnosed with cancer in 2023 and doctors had told her she had an 80 per cent chance of recovery if she underwent chemotherapy.
Her then-boyfriend said he received a text from Kate in block capitals, warning: ‘TELL PALOMA NOT TO SIGN IR (sic) VERBALLY CONSENT TO CHEMO OR ANY TREATMENT.’
Paloma did not agree to chemotherapy – even as doctors expressed concern over her mother’s overt influence – and instead reached out to a former partner of Kate’s.
The ex – who has since claimed that the idea that he had a role in her death was ‘legally inaccurate’ – told her to consider Gerson therapy, a baseless treatment that claims a plant-based diet and routine of coffee enemas can treat cancer.
Established cancer charities and researchers say there is absolutely no proof that Gerson therapy can help with cancer treatment, and that any studies seemingly proving its efficacy have been funded or performed by pro-Gerson organisations.
Kate has today shared what appeared to be a court statement authored and signed by Paloma, seemingly dated April last year, in which the 23-year-old allegedly claimed to be a ‘staunch advocate’ for Gerson therapy.
She claims the statement was ‘written in (Paloma’s) own words, with full capacity, courage, and clarity’. This has been contested by Paloma’s siblings.

She has fired back furiously on what she labelled ‘defamatory reporting’ of her daughter’s death, including a written statement seemingly signed by Paloma

Kate Shemirani continues to share conspiracy theories online to this day (pictured in 2020 with Piers Corbyn at a Trafalgar Square anti-lockdown rally)
Bearing what appears to be the 23-year-old’s signature, it contains a denial that she was ever diagnosed with cancer and struck out the idea that she was being cut off from the world by her mother.
‘I do NOT have a Non-Hodgkin’s lymphoma b diagnosis. It is a differential diagnosis in which cancer could not be ruled out,’ the statement reads. ‘To suggest I am being isolated is ridiculous.’
The statement also continues an assertion, first made by her mother, that Kate overcame her own breast cancer with an ‘all-natural protocol’ – but does not mention the double mastectomy Kate underwent to halt the cancer’s progress.
However, Gabriel and Sebastian have both indicated that they believe the document to have been written by their mother, and signed by Paloma under duress or in a state of reduced mental capacity.
The pair – who have been estranged from their mother for years – both refer to her by her legal name of Kay.
Sebastian told MailOnline today: ‘When I read the statement, I read it in Kay’s voice in my head – that’s how obvious it is to me, as someone who escaped Kay’s brainwashing, that it was written by Kay.’
‘Kay wants you to believe that these are actually Paloma’s words,’ Gabriel said in a response on social media.
The statement includes misinformation claiming that King Charles has opted for ‘natural medicines and treatment for his own cancer diagnosis’.
In reality, no details of the King’s treatment for cancer have been shared publicly – though he has alluded to losing his sense of taste, a common side-effect of undergoing chemotherapy.
Kate has further accused the NHS of being responsible for her daughter’s death, without evidence. She has also accused doctors, coroners, lawyers and the media of suppressing ‘medical negligence’.
The brothers, along with some of Paloma’s friends and a former boyfriend, went public earlier this week with their fears that the straight-A student had been coerced into refusing mainstream medical treatment by Kate.
Speaking to the BBC’s Panorama programme on Monday, Sebastian had said: ‘My sister has passed away as a direct consequence of my mum’s actions and beliefs and I don’t want anyone else to go through the same pain or loss that I have.’
Sebastian previously claimed his his childhood was ‘hell’ amid years of brainwashing, describing how he was left terrified aged 10 when Ms Shemirani told him ‘the Rothschilds are planning to go live on a space station and how there’s going to be this mass genocide’.
