Different Guidelines for Routine Mammography Screening in the United States
Introduction
Medical organizations in the United States have different recommendations regarding when women at average risk should start routine mammograms and how often they should have them.
Main Body
Currently, major health institutions do not agree on the best protocols. For example, the American College of Physicians suggests screenings every two years for women aged 50 to 74, while advising those aged 40 to 49 to discuss the pros and cons with their doctor. In contrast, the U.S. Preventive Services Task Force now recommends screenings every two years starting at age 40. Meanwhile, the American Cancer Society prefers annual screenings for women aged 45 to 54, although it allows them to start at 40. Furthermore, these organizations disagree on when to stop screening for women aged 75 and older; some suggest a clinical review to stop, whereas others believe healthy women should continue. These differences exist because it is difficult to define an 'average' risk, as breast cancer affects every woman differently. While age is a primary factor, doctors must balance the benefits of early detection against the stress and physical problems caused by false positive results. Additionally, nearly 50% of women over 40 have dense breast tissue, which makes diagnosis more difficult. Consequently, the American College of Physicians suggests using digital breast tomosynthesis (DBT) to improve accuracy. To solve these problems, research is moving toward personalized screening. The WISDOM trial, which included about 46,000 participants, showed that screening based on individual risk—using genetic data, lifestyle, and breast density—was as effective as annual screening for everyone. Interestingly, the trial found that 30% of women with a genetic risk had no family history of the disease. In the future, experts expect to use more genetic testing and artificial intelligence to predict risk more accurately.
Conclusion
Although screening rules are currently inconsistent across different institutions, there is a clear shift toward personalized, risk-based assessments.

⚡ The 'Logical Bridge' Strategy
An A2 student usually writes simple sentences: "The rules are different. Doctors are confused." To reach B2, you must stop using simple dots and start using Connectors of Contrast and Consequence. This is how you glue your ideas together to sound professional.
🧩 The Contrast Pivot
Look at how the text moves between different opinions. It doesn't just say "but"; it uses sophisticated anchors:
- "In contrast..." Used when two things are completely different (e.g., One group says age 50, in contrast, the other says age 40).
- "Whereas..." Used to compare two facts in one single sentence (e.g., Some suggest stopping, whereas others believe they should continue).
- "Although..." Used to show a surprise or a limitation (e.g., * Although rules are inconsistent, there is a clear shift*).
📉 The Result Chain
B2 fluency is about showing cause and effect. Notice these high-level triggers in the text:
Consequently This is the formal version of "so." Use it when a scientific or logical result happens. (Dense tissue makes diagnosis hard Consequently, DBT is suggested).
