A new bad cancer screening method could allow doctors to control women more or less often, depending on the risk of developing the disease.
Using information gathered from several techniques, the researchers discovered that they could accurately predict the risk of bad cancer in a person in the next 10 years.
The researchers said the method gave a "clearer picture" of the risk of bad cancer and that screening tools could be "adapted" to a person.
The study, conducted by the University of Manchester, was published in the journal Breast Cancer Research and Treatment.
In the United Kingdom, women are usually screened every three years between the ages of 50 and 70, but some of them are offered checks more frequently if they have a family history of bad cancer.
"Screening and predicting the risk of bad cancer in a woman is largely based on standard risk factors, such as their age, weight, family history, and other characteristics," said Professor Gareth. Evans, who directed the research.
"This research shows that risk prediction is gradually improving because you combine these factors with information on bad density and common genetic variation that many of us carry and which we know to be increase the risk.
"This combined method gives women a much clearer idea of their likelihood of developing bad cancer, possible treatments to reduce their risk and, if so, their likelihood of responding to different treatments."
The risk of bad cancer is currently predicted with the help of the Tyrer-Cuzick model, which badyzes the factors likely to increase the probability of developing the disease.
The researchers found that the combination of this method, genetic testing, and bad density measurements was effective in determining whether women were at low, medium, medium, or moderate to high risk of developing bad cancer. over the next decade.
This information could help doctors to offer women at higher risk than average risk more regular screening, as well as preventive treatments such as drugs or surgery.
They could also reduce screening in low-risk groups, which would reduce overdiagnosis and over-treatment, said the authors.
Nikki Barraclough, executive director of the charitable organization Prevent Breast Cancer, which funded the study, said, "The innovative research conducted by Professor Gareth Evans shows how bad cancer screening can be adapted to each woman and suggests that the screening frequency could potentially be modified. match the risk of a person.
"This research allows us to move from a unique approach to an approach that more accurately predicts the risk of bad cancer in a woman, depending on various risk factors such as DNA, density mammary, family history and lifestyle factors.
"The new findings from this study show that by combining several techniques, we can better understand a woman's risk, which could also have consequences on the way we currently screen people."
