5 Things You May Not Know About Breast Cancer

Breast cancer is the second most common cancer in the United States following skin cancer.¹ This Breast Cancer Awareness Month, we would like to provide you with interesting facts about breast cancer from risk to survivorship.

The Main Differences

1. Genetics. Some people have genes, portions of their DNA that increase their risk of breast cancer. For example, people with BRCA 1 and 2 genes are at ~50% higher risk of developing breast cancer.¹ Some individuals may be recommended for genetic testing based on their history for breast cancer. Getting the results can be anxiety-inducing– but know there are actions (for example hormone therapy) that you can take if you test positive for one of the gene variants for breast cancer. Talk to a trusted provider to see if genetic testing is right for you.
   
2. Risk. Overall, the probability that a woman will develop breast cancer is 1 in 8 or 13% in the United States. However, this risk can be reduced by a variety of factors, from maintaining a healthy body weight, to reducing alcohol consumption, to opting to breastfeed for mothers.
   
3. Onset. There are a variety of signs associated with breast cancer beyond a lump. The initial signs may include changes in nipple appearance and discharge, breast warmth or itchiness, swelling around the breast and armpits. It is important to note any physical changes regarding your breast health to a provider.
   
4. Screening. According to the United States Preventive Services Task Force, it is recommended that all women start mammograms at age 40. However, if you are at high risk (ex: family history, genetic history, etc.), you may start screening as early as 30 years old. Currently, research is being done on other imaging exams, such as ultrasound, to see if cancer detection is more efficient for women that may have breasts.
5. Survivorship. Cancer deaths have declined over 40% in the last two decades.² This can be due to advances in medicine and breast cancer screening. However it is important note disparities in breast cancer mortality exist as Black women are more likely to die from this cancer.
