“Revolutionary” surgical knife could detect womb cancer within seconds, say experts
The device can identify the presence of endometrial cancer with nearly 90 per cent accuracy
A surgical knife that “smells tumours” can diagnose womb cancer within seconds, researchers at Imperial College London have revealed.
Around 9,400 women are diagnosed with endometrial cancer, also known as uterine or womb cancer, in the UK each year. This makes it the country’s fourth most common cancer in women and the sixth most common globally.
However, only about 10 per cent of those with suspected symptoms who undergo a biopsy are found to have it.
Researchers have now found that the iKnife, a device that is already used to treat breast and brain cancers, can detect the presence of endometrial cancer with nearly 90 per cent accuracy.
Writing in the journal Cancers, the research team said: “The iKnife reliably diagnosed endometrial cancer in seconds, with a diagnostic accuracy of 89 per cent, minimising the current delays for women whilst awaiting a histopathological diagnosis. The findings presented in this study can pave the way for new diagnostic pathways.”
According to Imperial College London, the iKnife is based on electrosurgery, a technique invented in the 1920s often used in surgery to control bleeding and to rapidly dissect soft tissue in surgery.
Electrosurgical knives use an electrical current to heat tissue, cutting through it while minimising blood loss. In doing so, they vaporise the tissue, creating smoke that is normally sucked away by extraction systems.
The iKnife’s inventor, Dr Zoltan Takats of Imperial College London, connected an electrosurgical knife to a mass spectrometer, an analytical instrument used to identify chemicals in a sample.
The device can tell the difference between cancerous and healthy tissue by analysing the smoke produced when tissue is vaporised.
The experts said its effectiveness was proved using biopsy tissue samples from 150 women with suspected womb cancer, and the results compared with current diagnosis methods.
Athena Lamnisos, chief executive of the Eve Appeal cancer charity which funded the research, told the Guardian: “Waiting for test results is stressful – especially if that test is to find out whether or not you have cancer. When you hear that the ‘c’ word is even a possibility, the days can’t pass quickly enough until a clinician gives you the all clear.
“Womb cancer has one ‘red flag’ symptom of postmenopausal bleeding that should always get checked out on a two-week referral from your GP. To wait a further two weeks for the results can be really hard for patients.
“There are many reasons for abnormal vaginal bleeding after the menopause – womb cancer is just one of them – the ability to provide a diagnostic test that rules cancer in or out immediately, and with accuracy, could make such a positive difference.
“This Eve-supported research has the potential to create a step change in faster diagnosis, and for the 90 per cent of women with postmenopausal bleeding that isn’t cancer, a really effective way to put their minds at ease. We know how important this is for patients.”
Prof Sadaf Ghaem-Maghami, who led the research, told the newspaper the iKnife has the potential to completely revolutionise the way healthcare professionals manage people seen in the rapid-access clinics with significant abnormal vaginal bleeding who have been referred for potential diagnosis of endometrial cancer.
“With its high diagnostic accuracy of 89 per cent and positive predictive value of 94 per cent, one could immediately reassure the person of the very low likelihood of having cancer if the iKnife result is negative and expedite further tests and scans and treatment for people whose biopsies indicate presence of cancer.
“This could happen whilst awaiting confirmation from standard pathology, which can take up to two weeks,” he added.
The World Health Organization (WHO) has launched an AI tool in beta to help policymakers, experts and healthcare professionals access sexual and reproductive health information faster.
Called ChatHRP, the tool was created by WHO’s Human Reproduction Programme and draws only on verified research and guidance collected by HRP and WHO.
It uses natural language processing and retrieval-augmented generation to produce referenced content and cut the time spent searching through documents across different platforms and databases.
WHO said ChatHRP also has multilingual capabilities and low-bandwidth functionality to support use in a wide range of settings.
The beta-testing phase is aimed at a broad professional audience, including policymakers, healthcare workers, researchers and civil society groups.
WHO said the tool can help users quickly access up-to-date evidence, find sources for academic work and verify information on sexual and reproductive health and rights.
Examples of questions it can answer include the latest violence against women data in Oceania for women aged 15 to 49, recommendations on managing diabetes during pregnancy, and whether PrEP and contraception can be used at the same time. PrEP is medicine used to reduce the risk of getting HIV.
WHO added that the system will be updated regularly as new HRP materials are published and includes a feedback loop so users can flag gaps in the information provided.
The launch comes amid wider concern about misinformation in sexual and reproductive health.
A 2025 scoping review found that misinformation in digital spaces is a systemic issue that can undermine human rights, reinforce discriminatory social norms and exclude marginalised voices.
The review also said misinformation can affect health systems by shaping provider knowledge and practice, disrupting service delivery and creating barriers to equitable care.
WHO said ChatHRP is intended to give users streamlined access to reliable information as a counter to “algorithms, opinions, or misinformation”.

An AI atlas has mapped how reproductive organs age through menopause, with the ovaries, vagina and uterus changing on different timelines.
To better understand how this process affects health, researchers at the Barcelona Supercomputing Center developed what they describe as the first large-scale atlas of female reproductive system ageing, using artificial intelligence.
The team combined 1,112 tissue images from 659 samples, covering 304 women aged 20 to 70, with gene expression data from thousands of genes.
This allowed them to reconstruct how seven key reproductive organs, including the uterus, ovary, vagina, cervix, breast and fallopian tubes, age over time.
The study used the supercomputing power of MareNostrum 5 together with advanced image-recognition methods to process the data.
Using deep learning techniques, the researchers detected visible tissue changes as well as the underlying molecular processes linked to ageing in each organ.
The result was a detailed, organ-by-organ map of the reproductive system’s ageing process.
The researchers found that not all organs age in the same way or at the same speed. The ovaries and vagina showed a more gradual ageing process that begins even before menopause officially starts.
By contrast, the uterus appeared to undergo more sudden changes around the time of menopause.
Even within a single organ, different tissues aged at different rates. In the uterus, for example, the mucosa, its inner lining, and the muscular layer did not change in sync. These tissues also appeared to be particularly sensitive to the hormonal and biological shifts associated with menopause.
Marta Melé, leader of the transcriptomics and functional genomics group at BSC and director of the study, said: “Our results show that it acts as a turning point that profoundly reorganises other organs and tissues of the reproductive system, and allows us to identify the genes and molecular processes that could be behind these changes.”
Building on the finding that organs age according to different patterns, co-first author Laura Ventura said the research “paves the way for personalised medicine where treatments are tailored to a woman’s specific molecular profile and the specific tissues showing the most age-related distress.”
The study also identified molecular signals linked to reproductive ageing that can be detected in blood samples from more than 21,441 women.
These biomarkers could allow doctors to monitor the condition of reproductive organs in a non-invasive way, potentially helping to anticipate risks such as pelvic floor complications without the need for biopsies.
According to the researchers, this could lead to simpler and more accessible clinical tools for tracking women’s health over time.
