Breast Cancer Screening. Breast cancer is one of the most common types of cancers, accounting for 15 percent of all new cancer diagnoses in the U.S. (Howlader et al, 2016). In 2013, over 3 million women were estimated to be living with breast cancer in the U.S. and it is estimated that 12 percent of women will be diagnosed with breast cancer at some point during their lifetime (Howlader et al, 2016). While there are other factors that affect a woman's risk of developing breast cancer, advancing age is a primary risk factor. Breast cancer is most frequently diagnosed among women ages 55-64; the median age at diagnosis is 62 years (Howlader et al, 2016). The chance of a woman being diagnosed with breast cancer in a given year increases with age. By age 40, the chances are 1 in 235; by age 50 it becomes 1 in 54; by age 60, it is 1 in 25 (National Business Group on Health, 2011). In the U.S., costs associated with a diagnosis of breast cancer range from $451 to $2,520, factoring in continued testing, multiple office visits and procedures. The total costs related to breast cancer add up to nearly $7 billion per year in the U.S., including $2 billion spent on late-stage treatment (National Business Group on Health, 2011). If breast cancer is detected through mammography screening and diagnosed in its earliest stages, treatment may be less expensive (Feig, 2011).
