Adenomyosis explained: how it differs from endometriosis, why it develops, and its impact on reproductive health

Tomioka opens this section with a claim that reframes the conversation: adenomyosis is 'the missed disease.' While endometriosis gets most of the attention, adenomyosis — where endometrial-like tissue invades the myometrium — may affect up to 20 to 30% of women, making it potentially two to three times more common. Though they share molecular features (progesterone resistance, aromatase overexpression, oncogenic mutations), single-cell transcriptomics — citing a paper by Linda Judis — shows they are distinct diseases with different pathways. The mechanism of adenomyosis is described as TIAR (tissue injury and repair): the endometrium breaches the junctional zone, typically after C-section, curettage, or miscarriage, and infiltrates the muscular wall, forming cysts and echogenic buds that enlarge and soften the uterus. Critically, up to 70% of endometriosis patients may have concurrent adenomyosis — a co-occurrence Tomioka believes has been a hidden confounder in implantation studies. Unlike endometriosis, adenomyosis is definitively cured only by hysterectomy, making fertility preservation a fundamentally different challenge for affected women.

AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
