Why are uterine cancer rates rising so drastically in black women?
According to a December 2018 report from the CDC, the number of new uterine cancer diagnoses increased an average of 0.7 percent per year between 1999 and 2015, resulting in an overall 12 percent rise. Rates of endometrial cancer, specifically, jumped 4.5 percent per year on average. The uterine cancer mortality rate increased 1.1 percent per year on average between 1999 and 2016, amounting to a 21 percent leap overall. What’s more, the burden of uterine cancer is greatest for black women, and the disparity is increasing with time. While that same CDC report found that non-Hispanic white and black women had similar incidences of uterine cancer (about 27 cases out of 100,000 people), black women were more likely to be diagnosed with uterine sarcoma, the most aggressive form of uterine cancer, than women of other races, and also more likely to be diagnosed at a later stage than women of other races. Teasing apart the potential reasons behind this disparity is a complex task. The puzzle pieces start to come together when you look at some of the major risk factors for developing uterine cancer. Let’s start with endometrial cancer risk factors. “We do know that obesity is one risk factor,” Michele L. Cote, Ph.D., a professor of Oncology at Wayne State University and associate center director of Cancer Research Career Enhancement, tells SELF. This is because it’s a health condition that can increase the amount of estrogen in your body. Another endometrial cancer risk factor revolves around children. “The more children you have, the lower your risk,” Cote says. Pregnancy increases your output of progesterone, so you might benefit from its protective effects against this cancer. But people are generally having fewer kids these days, Cote explains, including black women. “Unfortunately, we don’t have a lot of research data yet on why black women are more likely to have a more aggressive form of uterine cancer,” Cote says.
