In , the American Cancer Society recommended that annual screening mammograms start at age 45 and then change to having mammograms every 2 years starting at age Because of all the controversy and confusion, researchers have been studying the benefits and risks of having mammograms every year compared to every 2 years.
The researchers looked at breast imaging records at Michigan Medicine and identified women age 40 to 84 who were diagnosed with breast cancer in and All the women were having either annual or every-other-year mammograms:.
The researchers compared the tumor characteristics and treatment regimens of women who had annual mammograms to those of women who had mammograms every 2 years. The researchers found that women who had mammograms every year were more likely to be diagnosed with stage I cancer than women who had mammograms every 2 years:. Women who had mammograms every 2 years also were diagnosed with larger cancers. Average tumor size was:. Interval cancers, which are cancers found in the time between screenings, were more likely in the women who had mammograms every 2 years:.
Women who had mammograms every 2 years tended to have more aggressive treatment, such as chemotherapy and axillary lymph node surgery:. At Breastcancer. To not use all three tools in women ages 40 to 45 and to do mammograms alone without clinical or self-exam in women older than 45 are missed opportunities for early detection.
The reality is that every woman is at risk for breast cancer, and this risk tends to increase over time. To get the conversation started, here are some points to talk to your doctor about:. The Health First Breast Centers are state-of-the-art accredited facilities with the most advanced and sophisticated imaging and diagnostic technology available. According to the U.
Food and Drug Administration, 40 million mammograms are performed each year. Mammography is still considered the best method for screening women for breast cancer. For most breast imaging facilities in the country, mammograms have gone from analog film-based format to digital computer format. Under the EHIS survey, if a woman had ever undergone a mammography, she was also asked what her reasons for doing so were [8].
In England, from all women screened, There were no declared cases of women having been invited as part of the national screening programme in Latvia. In Latvia the EHIS survey was launched in meanwhile the national breast cancer screening programme was implemented one year later, in The variable asking for a reason of mammography was not included in the survey in France and Austria.
Austria runs since opportunistic screening: examination is conducted in non-dedicated mammography screening centers without active invitation neither control system [10]. In Denmark a national screening programme was introduced in meanwhile the Health interview survey was launched in In Greece, national breast-cancer screening programme was not implemented yet and some pilot projects run since In Slovak Republic preparatory steps for an implementation of a national breast-cancer screening programme began in For a number of countries, there are differences in having mammography by educational status.
Figure 5 shows the percentage distribution of women aged years ever screened by mammography, by educational status [11]. The gap between the top category and bottom categories is very large in Turkey and Bulgaria.
Spain, France and Belgium have the lowest inequalities by educational level. Figure 6 is similar to Figure 5 with the difference that the inequalities are shown by income quintile. For this illustration the first quintile Q1 and the top fifth quintile Q5 were used. The biggest discrepancy between income quintiles is in Latvia Participation rates in Austria and Spain are fairly good and can be considered satisfactory.
Inequality is the lowest in Romania but here general participation levels for both categories are also the lowest from all the countries studied. Finally, information about the type and onset of breast-cancer screening programmes essentially including mammography in the countries studied is provided in Table 2. The timelines vary between countries and between regions within countries.
