Breast Cancer: Risk Factors and Prevention

When malignant cells form in the tissues of the breast, breast cancer occurs. One in 8 women are diagnosed with breast cancer in their lifetime (Stuckey, 2011). Breast cancer also occurs in men; however, the number of cases is small compared to women accounting for only 1% of the breast cancer cases in the United States (Stuckey, 2011). Breast cancer is the third most frequent type of cancer in the world (Stuckey, 2011), and the second most common type of cancer in American women next to skin cancer. Over the past several years, deaths from breast cancer have decreased each year; however, it still remains the second most frequent cause of cancer related deaths in American women with lung

In addition, a person’s risk of developing breast cancer increases with age (Stuckey, 2011). One out of 8 invasive breast cancers are found in women younger than 45, while about 2 out of every 3 invasive breast cancers are found in women age 55 or older (American Cancer Society, 2014). The risk of breast cancer in a 70 year old woman is about 10 times that of a 30 year old woman (Stuckey, 2011). Having a family history of breast cancer is a risk factor (Stuckey, 2011). There are more people diagnosed with breast cancer whose close blood relatives have the disease. Having a first-degree relative, which is a mother, sister, or daughter, with a history of breast cancer approximately doubles a woman’s risk. Having two first-degree relatives with breast cancer makes a person three times more likely to develop breast cancer (American Cancer Society, 2014). Women with a personal history of a benign cancer disease have an increased risk of developing a second primary breast cancer (National Cancer Institute). Those diagnosed with breast cancer before the age of 40 are at higher risk and younger women have are three times as likely to develop any future cancer and are four and a
