Women at moderate risk of developing breast cancer may wait for 45 years before making an annual mammogram, calls the American Cancer Society (ACS), which recommended before starting from 40 years.
And a mammogram every two years is sufficient beyond 54 years if women are healthy and have a life expectancy of at least ten years, according to new recommendations published Tuesday in the Journal of the American Medical Association (JAMA).
The ACS also estimates that it is no longer necessary for all women, regardless of age, clinical breast exams to detect any lumps if they do not present any particular risk.
“After careful analysis of women 40 to 54 years, the group responsible for develop these recommendations concluded that the burden of disease was lower, although not negligible, for those aged 40-45 years and that the risks associated with mammography is not warranted in this age group, “wrote the ACS.
These changes, which could fuel the debate on age and frequency of such reviews in the US, is a recognition of the limitations of mammography and its through, such as the high number of results false positives that result in further analyzes such as biopsies.
But women between 40 and 44 with an increased risk of developing breast cancer, such as genetic predisposition, can make a yearly mammogram has the organization stressed.
The breast tumor is the most common cancer in women worldwide.
In the US, about 230,000 women should receive such a diagnosis in 2015. It is the second leading cause of cancer death among US women, after the lung.
Although mortality from breast cancer has declined steadily since 1990, largely due to earlier detection and treatment , 40,300 women still will succumb this year in the country, reports the ACS.
