‘Trans-affirming medics knew of sex-swap drugs cancer risk’, says US journalist

Shocking admissions of the harmful effects of ‘trans-affirming care’ have emerged in leaked files from the World Professional Association for Transgender Health (WPATH).

It is reported documents show that members of the pro-trans global group acknowledge a likely connection between cross-sex hormones and cancer and confess that some clients are too young to understand the irreversible nature of some interventions.

In 2022, WPATH removed minimum age recommendations for sex-swap drugs and surgery in its ‘best practice’ guidelines.

Terminal cancer

In content seen by US journalist Michael Shellenberger, one medic wrote: “I have one transition friend/colleague who, after about eight to 10 years of [testosterone] developed hepatocarcinoma [a form of liver cancer].

“To the best of my knowledge, it was linked to his hormone treatment… it was so advanced that he opted for palliative care and died a couple of months later.”

Another indicated their readiness to carry out a double mastectomy for a 16-year-old, despite the fact she had liver cancer.

The doctor noted: “The oncologist and surgeon both have indicated that the likely offending agent(s) are the hormones. We are prepared to support the patient in any way we can (e.g. top surgery when medically stable, etc).”


A hormone specialist, in material from a talk in 2022, said: “It’s always a good theory that you talk about fertility preservation with a 14-year-old, but I know I’m talking to a blank wall.

what is called ‘gender medicine’ is neither science nor medicine

“Most of the kids are nowhere in any kind of a brain space to really talk about it in a serious way.”

Among other revelations, a psychologist admits that it is out of the “developmental range” of a child to understand “the extent to which some of these medical interventions are impacting them”.

‘Shocking and disturbing’

Shellenberger said the WPATH files “show that what is called ‘gender medicine’ is neither science nor medicine”.

He added that activist members of the organisation “know that the so-called ‘gender-affirming care’ they provide can result in life-long complications and sterility and that their patients do not understand the implications.”

cavalier with respect to potential harm to patients

Responding to the news, consultant psychiatrist Dr David Bell, who was among those exposing Tavistock’s dangerous practices, commented: “Even for me the contents of these files are shocking and disturbing”.

Dr Louise Irvine, of the Clinical Advisory Network on Sex and Gender, said the files showed “an organisation that has been influential in UK policy for transgender health care is unscientific, cavalier with respect to potential harm to patients, and neglectful of the principles of medical consent”.


Writing in The Daily Telegraph, Professor Kathleen Stock observed: “To the average outsider stumbling across this information for the first time, an outraged response comes easily – which raises the interesting question of why ethical sensibilities within WPATH seem to be so coarsened.”

For years, the organisation has been mindlessly cited in British medical contexts as a source of ‘international best practice’

The academic continued: “In day-to-day life, this demand that gender be affirmed manifests itself as an expectation that a person’s preferred pronouns should be used, and that they get access to spaces, resources, and sports teams that best fit with their inner sense of who they are.

“But in the context of medicine, affirmation requires something even more serious: access to irrevocable drugs and surgeries in order to try to make a person’s outer body fit with their inner feelings and ideas.”

And she warned: “The scandal of an international organisation like WPATH may seem irrelevant to the UK, but it is not. For years, the organisation has been mindlessly cited in British medical contexts as a source of ‘international best practice’.”
