Dubai, United Arab Emirates (Frylooz) – A new study has found that conducting annual breast cancer screenings early, that is, around the age of 40, can reduce breast cancer deaths during the first decade of screening.
The study, published in “The Lancet Oncology” on Wednesday, showed that the decrease in mortality “by 25% was related to the annual call for mammography between 40 and 49 years of age during the first ten years.”
The researchers, from various institutions in the United Kingdom, Israel, the United States and Russia, analyzed data from more than 160,000 women in Britain who participated in the UK’s “Lifetime Experience”, a randomized screening trial established in 1991.
The women, aged 39 to 41, were randomly assigned to begin annual mammograms or to continue with the standard care in the UK, which is not to have the imaging done until around the age of 50.
Women who followed standard care were not aware of the study.
After 10 years of follow-up, researchers found that of the total 53,883 women who had mammograms annually in their forties, 83 women had died of breast cancer, about 0.15% of the group.
In comparison, the researchers found that 219 women died of breast cancer out of a total of 106,953 women who followed standard care, about 0.20% of the group.
When examining the two groups after the first ten years of follow-up, the researchers found no significant difference in breast cancer mortality.
The researchers wrote in the study: “Our results indicate a decrease in breast cancer mortality when performing mammography in women between the ages of 40 and 49 years, during the first ten years of follow-up, and the absence of an overdiagnosis, in addition to what results from examination at the age of 50.” Years and older. “
However, there were some limitations to the study, one of which was that the examination took place during the 1990s and early 21st century. Since then, there have been some changes in diagnostic, screening and treatment methods.
In general, medical groups in both the UK and the US have made different recommendations about breast cancer screening.
In turn, the American Cancer Society says that women, who range in age from 40 to 44, have the option to initiate annual check-ups, if they wish.
However, it also recommends that women between the ages of 45 and 54 have a mammogram every year, and then every two years for ages 55 and over.
The American College of Obstetricians and Gynecologists recommends annual mammograms, starting at age 40, for all women.
The US Preventive Services Task Force also recommends mammograms every two years, starting at age 50, for all women.
In the United Kingdom, women, from the age of 50 to 71, are invited to be tested every three years, according to the National Health Service.
