Using low-energy X-rays, mammography equipment is used to screen and diagnose potential abnormal growths within the breast, which could include breast cancer or micro-calcifications that could eventually become breast cancer. The process is essentially the same as any other X-ray, but it uses less energy than X-rays used to visualize bone material. A mammography works by placing the breast between the X-ray source and image generator, and it is one of the most common tools for detecting breast cancer at any stage. Other imaging tools might be used in conjunction with the mammography equipment to create a more comprehensive diagnosis.
