"Unfortunately, college-age women generally do not consider themselves at risk for breast cancer," said Dr. Mercier. "However, there are several risk factors that contribute to the development of breast cancer that need to be understood early in life to prevent the development of breast cancer down the road."
By the end of 2013, more than 230,000 new cases of invasive breast cancer are expected to be diagnosed in the U.S. Of those cases, approximately 40,000 individuals will not survive, said Dr. Mercier. Women in their early 20s need to become aware of some key risk factors associated with breast cancer:
1) Check your family tree. A family history of breast cancer, particularly in a mother or sister, can increase the chance for developing breast cancer. Genetic testing is recommended for young women with prevalence of breast cancer in their families.
2) Watch your weight. Obesity is responsible for up to 20 percent of cancer-associated deaths in women. Being overweight or obese increases the risk of breast cancer by creating a cancer-friendly environment through fat cells.
3) Exercise regularly. Women who strive for at least 2.5 hours per week of moderate-intensity activity — like brisk walking — reduce their risk of breast cancer by 18 percent.
4) Limit alcohol consumption. According to new research from Washington University School of Medicine, if a female averages a drink per day, her risk of breast cancer increases by 11 percent. Studies show that alcohol possesses estrogenic activity, thus promoting the growth of breast tumor cells.
5) Annual doc visits. Although mammograms are not recommended for women under the age of 40, young women should still see their primary care doctors each year for clinical breast exams. They are also encouraged to conduct self-examinations throughout the year.
6) Limit tobacco use. Women who smoke have an increased risk of developing breast cancer, especially if they become smokers early in life. Smokers have increased levels of both estrogen and testosterone that might disrupt the endocrine signaling in women and contribute to the development of these tumors.
