Not about anesthesia but I wanted to share this with our readers.
Breast cancer incidence is rising among U.S. women under 50, according to new research published in JAMA Network Open .
This includes elevated diagnosis rates for non-Hispanic Black women in their 20s and 30s, before the disease is even on their radar. Experts believe the data underscore the importance of better understanding risk factors for younger patient populations, along with targeted prevention strategies for at-risk groups.
“For most women, regular breast cancer screening does not begin until at least age 40, so younger women diagnosed with breast cancer tend to have later-stage tumors, when the disease is more advanced and more difficult to treat,” senior author Adetunji T. Toriola, MD, PhD, a professor of surgery at the Washington University School of Medicine in St. Louis, said in an announcement. “This research offers a way to begin identifying the factors driving these increasing rates, with the goal of finding ways to slow or reverse them.”
Toriola et al. noted that the uptick was almost entirely due to an increase in tumors that are estrogen-receptor positive, where proteins on the surface bind to estrogen and fuel growth. Meanwhile, the incidence of tumors without the estrogen receptor dropped during the 20-year period. Black women also saw higher incidence rates, with a 53% increased risk of breast cancer in their 20s compared to white women of the same age. Same for in their 30s, though the greater risk fell to 15% and then dropped to below the rate of white women in their 40s.
“We are hopeful this study will offer clues to prevention strategies that will be effective in younger women, especially younger Black women, who are at particularly high risk of developing breast cancer before age 40,” Toriola said in the announcement.
