Women with a family history of breast cancer continue to experience the same increased risk of developing aggressive tumors, even after the age of 65, according to a new major US scientific study.
Researchers, led by Associate Professor of Oncology, Djetana Breitewatt of Georgetown University School of Medicine, who published the publication in the American Medical Journal “JAMA Internal Medicine”, analyzed data from more than 400,000 senior women.
It has been found that while on average an adult woman has a 12% risk of developing breast cancer sometime in her life, those with a family history (for a relative first degree) have almost twice the risk.
In particular, in women aged 65 to 74-year-old with dense areas of dense tissue in their breasts (density is a risk factor), the risk of breast cancer within the next five years ranges from about 15% (without family history) to 24% relatives who had breast cancer).
Similarly, for women over 75-year-old, the risk increases from 16% (no family history) to 23% (with a family history).
“Family history does not weaken as a risk factor for breast cancer, as long as a woman grows. Essentially, if there is a relative history in a first-degree relative, that is to say, a mother, sister or daughter, the risk is no different either a woman is less than or greater than 50 years of age, “said Breitwick.
This finding, should be borne by a woman’s decision to continue mammography as it ages. According to official US recommendations, women aged 50 to 74 (at medium risk) should have mammography every two years, and for those over 75 years there is no clear “balance” of mammography risks and benefits (there is a risk because of the radiation of the test).
The American Cancer Society is an annual mammogram for women aged 45 and every two years after the age of 55 when the woman is healthy.
