After skin cancer, breast cancer is the most common cancer in women. About every three minutes, a woman somewhere in the United States is diagnosed with breast cancer.
In 2014, an estimated 233,000 new cases will be diagnosed in American women. About 2,400 cases will be detected in men. Breast cancer is second leading cause of cancer death in women; lung cancer is number one. In 2014, approximately 40,000 women and 430 men will die of the disease.
An individual woman's odds of developing breast cancer depends on her age, as well as other specific risk factors, such as ethnicity, genetics and hormonal factors, including the age of menstruation and menopause. Statistics show that an American woman living to the age of 85 has a one in eight chance of developing breast cancer sometime in her life. The risk is not evenly spread over a women's lifetime. For example, a 25-year-old woman has a lifetime risk of one in eight, but her current risk is only one in 19,608.

|By age 40||.........||1 in 217|
|By age 50||.........||1 in 53|
|By age 60||.........||1 in 22|
|By age 70||.........||1 in 13|
|By age 80||.........||1 in 9|
More than three in four cases of breast cancer occur in women older than 50.
