What is the purpose of mammography screening in women over a certain age?

Mammography screening is specifically designed to identify breast cancer at an early stage in women, particularly those over a certain age, typically starting at 40-50 years. Early detection of breast cancer is crucial because it allows for earlier intervention, which can improve treatment outcomes and increase survival rates. Mammograms utilize low-energy X-rays to produce images of breast tissue, helping radiologists to spot abnormalities such as tumors before they can be felt physically.

The significance of this screening lies in its ability to find cancer when it is most treatable, often before symptoms arise, thus maximizing the chances for successful management of the disease. Regular screening is a vital component of preventive healthcare, contributing significantly to the reduction of breast cancer mortality.
