Knowing if you have a high risk of developing breast cancer allows you to catch it in its early, most treatable stages. People with the highest risk of developing breast cancer should discuss early screening methods with their doctors. Some common screening tools for breast cancer include breast self-examination, a clinical breast examination and a mammography. It is important to understand that while you cannot change some risk factors of the disease, others, such as weight and diet, are within your control.
Personal and Family History
Women have the greatest risk of developing breast cancer. According to the American Council on Science and Health, women who have previously had breast cancer or who have immediate family members with breast cancer are at a high risk of developing the disease. Immediate family members include a daughter, sister or mother. A gene mutation may be responsible for this familial link. The Mayo Clinic reports that gene mutations known as BRCA1 and BRCA2 increase the likelihood of developing breast cancer.
Age
While breast cancer can strike young women as well as older women, the Mayo Clinic reports that women over the age of 60 are more likely to develop breast cancer than women who are 60 or younger.
Menstrual and Reproductive History
According to the Centers for Disease Control (CDC), several patterns may affect the development of breast cancer in later life. Early onset of menstruation and starting menopause at an older age both increase the likelihood of developing breast cancer. Not having your first child until you are older, not breastfeeding and taking oral contraceptives all increase the risk of developing breast cancer as well, reports the CDC.
Weight and Fitness
The American Council on Science and Health reports that a number of lifestyle issues can affect your likelihood of developing breast cancer. They include gaining weight after the onset of menopause, being physically inactive and eating a diet low in fiber and high in fat.
