In a disturbing trend, more and more younger women are being diagnosed with later stage breast cancer.
A study recently found that between 2000 and 2015, the number of women below the age of 40 who were diagnosed with Stage 4 breast cancer increased by more than 4%. According to the American Cancer Society, women below the age of 40 account for approximately 6 percent of all breast cancer cases diagnosed in the United States.
Stage four breast cancer is the most lethal stage of the disease, and at this point, it is very likely that cancer cells have spread to other areas of the body and infected other organs, including the lungs and liver. According to another study, approximately 27% of people who have been diagnosed with stage four breast cancer live for an average of 5 years after the diagnosis. The Centers for Disease Control and Prevention says that, overall, 11% of all persons diagnosed with breast cancer are below the age of 45.
