Breast cancer incidence in women by age group. Breast cancer is the most common invasive cancer in women in most countries, accounting for 30% of cancer cases in women. [151] [113] In 2022, an estimated 2.3 million women were diagnosed with breast cancer, and 670,000 died of the disease. [151]
Breast density is assessed by mammography and expressed as a percentage of the mammogram occupied by radiologically dense tissue (percent mammographic density or PMD). [24] About half of middle-aged women have dense breasts, and breasts generally become less dense as they age. Higher breast density is an independent risk factor for breast cancer.

You may also have heard of risk factors of breast cancer, such as family history, race, current or recent use of birth control, getting your period at an earlier age and smoking, just to name a few.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Medicare will cover bone density scans for people who meet certain medical requirements, such as having osteoporosis risk factors. People should check with Medicare before having a bone density ...
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Mammography. Mammography (also called mastography: DICOM modality = MG) is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses or microcalcifications.
