At what age should women begin annual mammograms for breast cancer screening?

• A. 45 years old
• B. 50 years old
• C. 55 years old
• D. 60 years old

Answer: (B)

Women should begin annual mammograms for breast cancer screening at the age of 50 because this is the common guideline established by major health organizations, including the American Cancer Society and the US Preventive Services Task Force. The age of 50 marks a significant point in terms of risk; breast cancer incidence increases notably after this age. Starting routine screening at this age aims to detect breast cancer early when it is most treatable and before any symptoms might appear.

Data show that screening individuals in their 50s contributes to a reduction in breast cancer mortality, and the balance of benefits and harms of screening tends to favor this age group when considering factors like false positives and the psychological impact of screening. Some recommendations suggest that women with risk factors may start earlier, but for average-risk women, 50 is the age when systematic screening is advised.
