Australian scientists make world-first endometriosis treatment breakthrough
The findings could help researchers determine whether a woman will need fertility treatment
A team of Australian researchers has become the first in the world to grow tissue from every known type of endometriosis, in a move that could pave the way for new research into more effective treatments and diagnoses.
Researchers from the Royal Hospital for Women, Sydney will be able to test treatments and match patients’ symptoms with specific proteins, after successfully growing 30 different lab-grown tissues taken during surgery.
The advancement will not only allow scientists to vary treatments from different types of endometriosis, but it will also help them determine whether a woman will need fertility treatment in the future.
Endometriosis is a common disease where tissue similar to the lining of the womb grows outside it in other parts of the body.
According to Endometriosis Australia, more than 830,000 of Australian girls and women live with endometriosis at some point in their life, with the disease often starting in teenagers. However, symptoms can vary dramatically between patients.
The charity estimates the illness costs the country AUS$9.7bn per year, with AUS$2.5bn coming in direct healthcare costs, and the rest in lost productivity.
Professor of obstetrics and gynaecology at Sydney Royal Hospital for Women, Jason Abbott, said collecting the cells in one place for the first time would allow researchers to accurately diagnose patients, potentially limiting the need for invasive and painful surgeries.
“Very much like we thought breast cancer, 30 years ago, was one disease and treated in one way, we now understand that [endometriosis] is much more complex than that,” he told Brisbane Times.
“All those different types of endometriosis really probably reflect different diseases … and that [can determine] their response to treatment, clinical symptoms and also things like infertility.”
The development, Abbott said, would help fast-track new treatments by enabling researchers to test new and existing drugs on the lab tissues rather than in humans.
“It’ll mean that we’ll be offering new treatments just around the corner,” he added.
Endometriosis has often been referred to as the ‘missed disease’ due to its unclear aetiology and inconsistencies in its diagnosis and management.
Unlike other long-term conditions such as diabetes and asthma, reports suggest endometriosis has remained largely ignored in government policy and research funding globally.
A 2021 study concluded that while social science and feminist research has drawn attention to the historical absences around endometriosis and the exclusion of women’s accounts, more empirical work which explores the active construction of ignorance around endometriosis in contemporary healthcare and policy contexts is urgently needed.
Type 2 diabetes diagnoses are rising twice as fast in women under 40 as in women over 40, new data shows.
Type 2 diabetes is a serious condition and can lead to complications such as heart attacks and strokes. When it develops in younger people, it can be more aggressive and have more severe and acute effects.
Diagnoses in women under 40 rose by 47 per cent between 2017/18 and 2023/24. By comparison, diagnoses rose by 22 per cent in women aged 40 to 79.
During the same period, type 2 diabetes diagnoses in men under 40 increased by 34 per cent.
Diabetes UK said it is concerned about the follow-up care offered to women who have had gestational diabetes, also known as GDM, which increases the risk of developing type 2 diabetes after pregnancy.
Gestational diabetes is high blood sugar that develops during pregnancy and usually goes away after birth, but it raises the risk of type 2 diabetes later.
Colette Marshall, chief executive at Diabetes UK, said: “These figures should be a wake-up call. Type 2 diabetes is rising twice as fast in younger women compared to older women, and a crucial opportunity for prevention is being missed. Every diagnosis is life-changing, but when it develops in younger people, type 2 diabetes is even more aggressive.
“Pregnancy shouldn’t be a pathway to ill health. Yet despite facing a much higher risk of type 2 diabetes, too many women with GDM receive little or no follow-up care after pregnancy.
“As the Government turns its Strategy into action, support for women who have had gestational diabetes must not be overlooked.”
Last year, the NHS published the first national GDM audit for England in 2024/25, which revealed inconsistencies in follow-up care.
Only 57 per cent of women with GDM received an annual HbA1c test, which should be offered to every woman with GDM.
An HbA1c test measures average blood sugar levels over the previous two to three months.
Only 4.5 per cent of women had received support through the NHS Diabetes Prevention Programme.
The report also found that 11 per cent of women developed prediabetes within five years of having GDM, while 15 per cent developed type 2 diabetes within 10 years.
Prediabetes means blood sugar levels are higher than normal and a person has a higher risk of developing type 2 diabetes.
A recent survey funded by Diabetes UK also found that more than a third of women with GDM felt abandoned by healthcare services after giving birth.
If you live in England and have had gestational diabetes, you can self-refer to the NHS Diabetes Prevention Programme, which supports people at risk of developing type 2 diabetes. If you live in Northern Ireland, Scotland or Wales, you can speak to your GP about support.
Diabetes UK has written to women’s health minister Baroness Merron calling for urgent improvements to postnatal support for those diagnosed with GDM during pregnancy.
GDM affects between 10 and 20 per cent of pregnant women, but Diabetes UK said cases have long been underreported and UK-wide data on the condition has not been readily available.
The charity said poor follow-up care for women who have had GDM may be contributing to rising rates of type 2 diabetes in younger women.
It is calling for consistent postnatal follow-ups for women after GDM, more referrals to the NHS Diabetes Prevention Programme, greater accountability for improvements in postnatal care, and action on inequalities affecting women from deprived and minority ethnic communities.
Smartwatch data may help track menopause sleep changes after researchers analysed more than 94,000 nights of Apple Watch sleep records.
The study analysed more than 94,000 nights of sleep data from 338 participants in the Apple Women’s Health Study.
It found that many participants spent more time awake during the night in the 12 months before and after their final logged menstrual period.
For the past several years, Apple has used the Apple Watch to support large-scale health studies through the Apple Research app.
These include the Apple Women’s Health Study, the Apple Heart and Movement Study, and the Apple Hearing Study, which launched in 2019 with research partners including Harvard, Brigham and Women’s Hospital, the American Heart Association and the University of Michigan.
In February 2025, Apple said those studies had grown to more than 350,000 participants across the US.
Recently, researchers at Harvard T.H. Chan School of Public Health published results on how sleep patterns change during perimenopause.
The study looked at wake after sleep onset, or WASO, which measures how much time a person spends awake after first falling asleep.
In the 18 months leading up to menopause, 60 per cent of women with sleep tracking data showed increased WASO compared with the previous six months.
The average increase was 7 per cent.
Researchers also found that, in the 12 months before and after the last logged menstrual period, participants spent about 0.8 per cent more of their sleep time awake after menopause than before.
However, the findings varied widely between participants.
Some women had much larger increases in time awake after menopause, while others had no meaningful sleep change at all.
The researchers said this reflects the fact that each person experiences perimenopause and menopause differently.
Participants who tracked sleep also logged menopause symptoms.
Hot flushes were reported by 82.3 per cent of participants, irritability by 68.1 per cent, mental exhaustion by 65.7 per cent and sexual symptoms by 65.6 per cent.
Among participants with more severe menopause symptoms, the symptoms most closely linked with worse sleep were bladder symptoms, joint symptoms, heart discomfort and depressive symptoms.
The researchers also shared recommendations that may help women sleep better during perimenopause.
These include maintaining a cool sleeping environment, keeping a consistent sleep schedule, getting regular movement, avoiding common bladder irritants and limiting fluids in the hours before bedtime, and prioritising relaxation or mindfulness techniques as part of a bedtime routine.
A genomic test may help some women with breast cancer avoid chemotherapy, with near-identical outcomes in an international trial.
The findings suggest patients with a low test score could be treated with hormone therapy alone without increasing the risk of their cancer returning.
Researchers said the results could support more personalised treatment decisions and spare some women the side-effects of chemotherapy.
Prof Rob Stein, the trial’s chief investigator and a professor of breast oncology at UCL, said: “Optima addresses a longstanding challenge in breast cancer care: identifying who truly benefits from chemotherapy and who does not.
“Our findings show that many patients can safely avoid chemotherapy without compromising their outcomes.
“These results mark an important and significant step toward more personalised treatment.
“The trial has successfully used tumour biology to guide decisions rather than relying solely on traditional clinical features.”
Breast cancer treatment usually involves surgery to remove tumours. Chemotherapy is then often recommended if doctors believe there is a risk the disease will return.
Chemotherapy can cause side-effects including hair loss, rashes, nausea, insomnia and fatigue. Some women may also face longer-term consequences such as infertility, cognitive impairment or early menopause.
The Optima trial followed more than 4,000 patients with newly diagnosed breast cancer in the UK, Norway, Sweden, Australia, New Zealand and Thailand.
The trial was led by University College London.
One woman who took part in the trial told the Guardian that being able to skip chemotherapy felt “like Christmas”. Nine years after being diagnosed, taking the test and skipping chemotherapy, she is healthy and enjoying a full and active life.
The trial tested whether a genomic test could identify which patients need chemotherapy and which could safely avoid it.
The Prosigna test, made by diagnostics company Veracyte, analyses the activity of 50 genes in tumour tissue. It identifies the molecular subtype of the cancer and gives a score estimating the risk of breast cancer returning in the next 10 years.
The randomised trial involved 4,429 patients aged 40 or over with hormone-positive breast cancer. Hormone-positive breast cancer grows in response to hormones such as oestrogen or progesterone. It is the most common form of breast cancer, accounting for up to 80 per cent of cases globally.
Participants were assigned to one of two groups. In the standard treatment group, patients received chemotherapy followed by hormone therapy.
In the second group, patients had their tumours analysed using the genomic test. Those with a high score received chemotherapy and hormone therapy. Those with a low score received hormone therapy alone.
Radiotherapy and other treatments were given as usual in both groups.
In the second group, outcomes were very similar whether chemotherapy was given or not. Five years after treatment, 95 per cent of patients who had chemotherapy and hormone therapy were alive and free from breast cancer recurrence, while 94 per cent of those who skipped chemotherapy were also alive and recurrence-free.
The findings suggest chemotherapy offered little or no additional benefit for patients with low test scores.
Some men also took part in the study, but researchers said there were too few to draw firm conclusions for this group.
The trial received funding from the National Institute for Health and Care Research, Veracyte and cancer charities.
Prof Iain MacPherson, a co-chief investigator and professor of breast oncology at the University of Glasgow, said: “Optima provides robust, practice-changing evidence that we can safely reduce the use of chemotherapy for many patients with hormone-sensitive breast cancer.
“These findings represent a major step forward in delivering more personalised, precise care, ensuring that treatment decisions are driven by what will genuinely improve outcomes for patients, while avoiding unnecessary toxicity.
“The potential impact for both patients and health services is substantial.”
