AI model could predict breast cancer risk without racial bias, study finds
The deep learning model has been shown to outperform traditional risk models in predicting a woman’s risk of developing breast cancer
A new AI model developed using mammogram image biomarkers could accurately predict both invasive and non-invasive forms of breast cancer without racial bias, new research has shown.
The findings, presented at the annual meeting of the Radiological Society of North America (RSNA), have suggested the model showed no bias across multiple races.
Traditional breast cancer risk assessment models use information obtained from patient questionnaires, such as medical and reproductive history, to calculate a patient’s future risk of developing breast cancer.
Data shows old models are more likely to demonstrate poor performance across different patient races, most likely due to the data used to develop the model.
“In the domain of precision medicine, risk-based screening has been elusive because we have not been able to accurately evaluate a woman’s risk of developing breast cancer,” said study lead author Leslie R. Lamb, a breast radiologist at Massachusetts General Hospital (MGH) in Boston.
“Even the best existing traditional risk models do not perform well on the individual level.
“Traditional models likely have racial biases due to the populations on which they were developed. Several of the commonly used models were developed on predominantly European Caucasian populations.”
According to the American Cancer Society, Black women demonstrate the lowest five-year relative survival rate for breast cancer among all racial and ethnic groups. This translates to a six per cent to eight per cent disparity in five-year survival rates between Black and white women across all breast cancer types.
The new deep learning AI risk assessment model developed using mammographic images has been shown to outperform traditional risk assessment models in future breast cancer development while also mitigating the racial biases seen in traditional models.
In the first study of its kind, Dr Lamb and colleagues assessed the performance of the image-based deep learning risk assessment model in predicting both future invasive breast cancer and non-invasive breast cancer across multiple races.
The study included 129,340 routine screening mammograms performed in 71,479 women between 2009 to 2018 with five-year follow-up data. Patient demographics were obtained from electronic medical records and instances of cancer were identified from the regional tumour registry.
The racial makeup of the study group included white, Black, Asian, self-reported and other races. The mean age of the women was 59 years old.
The deep learning model was shown to outperform traditional risk models in predicting a woman’s risk of developing early-stage, non-invasive breast cancer, also known as ductal carcinoma in situ (DCIS), as well as invasive breast cancer, known as invasive carcinoma.
“The model is able to translate the full diversity of subtle imaging biomarkers in the mammogram, beyond what the naked eye can see, that can predict a woman’s future risk of both DCIS and invasive breast cancer,” explained Lamb.
“The deep learning image-only risk model can provide increased access to more accurate, equitable and less costly risk assessment.”
Constance D. Lehman, senior author and breast radiologist at MGH, said: “This is a particularly exciting domain for AI, as it demonstrates the opportunity to apply ‘AI for good’—to reduce well-known racial disparities in risk assessment.
“We are now poised to translate these findings into improved clinical care for our patients.”
Housing, work and fertility pressures are stopping many Britons growing the families they want, new research suggests.
A UK fertility report found that 79 per cent of people surveyed who had tried to conceive in the past five years would like more children than they currently have.
Among parents with one child, that figure rises to 88 per cent.
The report surveyed more than 1,000 people across the UK who had tried for a baby in the past five years.
While birth rates continue to fall, the findings suggest it is not because people no longer want children. Instead, many respondents said external pressures are making it harder to grow their families.
The findings, from wellness brand Wild Nutrition’s Fertility Disconnect report, highlight how financial pressures, fertility struggles and gaps in reproductive health knowledge are shaping modern family life in the UK.
Gail Madalena, fertility nutritional therapist at Wild Nutrition, said: “People often assume fertility begins the moment they decide to try [for a baby].
“In reality, egg and sperm health are shaped months and years earlier.
“By the time someone starts thinking about fertility, their body has already been responding to its environment for a long time.”
Among the biggest barriers, 26 per cent said career progression affected their family plans, 25 per cent cited housing affordability and lack of space, and 52 per cent said they required medical intervention during their fertility journey.
The report also found that almost a quarter of respondents had spent more than two years trying to conceive.
Trying for a baby can take a significant toll on mental health and relationships, especially for those navigating fertility treatment.
According to the research, 38 per cent of respondents said trying to conceive had negatively affected their mental health. That figure rose to 99 per cent among people undergoing fertility treatment.
Julianne Boutaleb is a perinatal psychologist.
She said: “Navigating a fertility journey is about so much more than medical appointments and procedures.
“It’s an emotional marathon that can take a huge toll on your mental wellbeing.
“Sadly, the stats show that 15 per cent of couples going through fertility treatment say their relationship has been irrevocably impaired.”
The report also highlighted the realities of secondary infertility, which affects around one in 20 people, challenging the assumption that having one child means conceiving again will be straightforward.
Researchers found many people felt under-informed about fertility, particularly younger adults.
Ten per cent of Gen Z respondents said they “know nothing” about fertility, while only one in five respondents said they know “a lot” about egg health.
The report also found that 60 per cent of women were unaware of fertility testing options, and one in five Gen Z respondents said they felt uncomfortable discussing fertility, even with their partner.
Around 40 per cent of those surveyed supported fertility education being included in schools, covering topics such as egg health, sperm health and hormonal health.
The report also explored how lifestyle and long-term health may influence fertility outcomes.
Many respondents said they only made changes once they started trying to conceive.
Some 44 per cent improved their diet when trying for a baby, while 32 per cent reduced alcohol intake at that stage.
The report also referenced emerging research that suggests ultra-processed foods and microplastics could have an impact on reproductive health.
While fertility conversations often focus on women, the findings showed male fertility issues are also affecting many families.
Seventeen per cent of respondents cited sperm health issues as a barrier to conception, while male factors contribute to around half of all fertility challenges.
Only one in four men said they would share fertility struggles with friends.
“Many causes of male infertility are entirely treatable yet so often the last resort is the first response,” said Ian Stones, co-founder at Test Him Ltd.
The findings come as UK birth rates remain below replacement level.
The report noted that the UK fertility rate is now 1.41, meaning that on average women give birth to 1.41 children over their lifetimes. The replacement rate, or rate that maintains population numbers, is 2.1.
It also said the average age of mothers has risen to 31, while birth rates are falling across most age groups except among over-40s.
“There is no single fertility story, and it is rarely a simple, linear narrative,” said Dr Zeynep Gurtin, lecturer in women’s health at UCL.
Dr Gurtin added that better fertility education, fairer access to treatment and more open conversations around infertility and pregnancy loss are needed.

A common cholesterol drug could help weaken a fluid shield that helps ovarian cancer tumours survive, early lab findings suggest.
The findings do not show the drug treats ovarian cancer. But they suggest changing the environment the cancer depends on could make it more vulnerable to existing treatment.
A federally funded study at Duke University School of Medicine found that ascites, a build-up of fluid in the abdomen, may do more than cause discomfort.
Doctors can drain ascites to ease pain, improve mobility and make breathing easier, but the fluid may also help cancer cells survive and spread. It occurs in 90 per cent of people with advanced ovarian cancer.
According to the study, ascites acts as a shield, helping cancer cells evade ferroptosis, a form of cell death.
Ferroptosis is a kind of cellular rusting. It happens when iron inside a cell reacts with certain fats, causing the cell membrane to break apart.
Many metastatic cancer cells, meaning cells that float freely through the abdomen looking for new places to grow, are naturally vulnerable to this kind of damage.
“Doctors have mostly viewed ascites as a symptom rather than an active driver of disease,” said Jen-Tsan Chi, professor in the department of molecular genetics and microbiology and co-leader of the Cancer Biology Program at the Duke Cancer Institute.
“We’ve learned it gives cancer a survival advantage, which fills a major gap in understanding how ovarian cancer spreads.”
Scientists bathed cancer cell lines and patient-derived tumour cells in ascites collected from patients and watched how they responded to ferroptosis triggers.
The fluid protected cancer cells by changing how they store fats and control iron levels, effectively blocking cell death.
The protection required only trace amounts, with as little as 2 per cent immersion shielding cancer cells from destruction.
“What surprised us was how selective this effect was,” said Yasaman Setayeshpour, first author and graduate student in molecular genetics and microbiology at Duke School of Medicine.
“Ascites didn’t protect the cancer cells from other well-known types of cell death, like apoptosis or necrosis, it only blocked ferroptosis.
“To figure out why, we broke ascites down into major parts, like lipids, proteins, and small molecules, and tested what happened when each was removed.
“When we took the lipids out, the protective effect disappeared. That told us lipids are the key reason ascites helps these cancer cells survive.”
But researchers found an unexpected helper in bezafibrate, an older cholesterol drug used to lower triglycerides by altering how the body processes fats.
The cholesterol drug restored sensitivity to ferroptosis, but only when ascites was present. On its own, the drug did not trigger cell death or slow tumour growth in mice.
The drug’s impact depended on the cancer’s surroundings, in this case the fat-rich fluid bathing the tumour. Researchers found that targeting this environment, using repurposed drugs like bezafibrate, could leave cancer cells more exposed to existing cancer treatments.
Chi said the finding could have implications beyond ovarian cancer. Other cancers, including colorectal and pancreatic cancers, can also spread within the abdominal cavity.
“This work shows how much the environment around a tumour matters,” Chi said.
“Biological fluids like ascites don’t just give cancer cells a place to move. They actively help drive how cancer spreads.”
