At what age does routine mammography screening typically begin for average-risk women?

Explanation:
Starting at age 40 for average-risk women is when routine mammography typically begins. The goal of screening is to detect cancers earlier when treatment is more effective, while balancing potential harms such as false positives and unnecessary procedures. In younger women, breast cancer incidence is relatively low, so routine screening offers less overall benefit and increases false-positive results. Around the 40s, the risk begins to rise enough that the benefits of detection outweigh the harms, which is why the standard starting point in many exam contexts is 40.
