Despite a continuous decline in the rate of breast cancer deaths in the United States, the incidence of the disease has increased, especially among younger ages, and significant racial disparities remain, according to a new American Cancer Society report. <\/p>\n
The study, published Tuesday in CA: A Cancer Journal for Clinicians, found some good news: The overall breast cancer death rate in the US dropped about 44% between 1989 and 2022, which translates to almost 518,000 fewer breast cancer deaths during that time. This is largely <\/strong>thanks to advances in cancer treatments and in detecting illness early through screening, which is recommended for women at average risk starting at age 40. <\/p>\n But there was also some concerning news: The incidence of the disease itself climbed 1% each year from 2012 to 2021. <\/p>\n \u201cIf we look at the last decade or so, we\u2019ve seen breast cancer incidence rise at about a 1% year-over-year increase, and the steepness of that increase does not affect all women in this case equally,\u201d said Karen Knudsen, chief executive officer of the American Cancer Society and the American Cancer Society Cancer Action Network. <\/p>\n \u201cThere is a slightly higher increase in the rate of breast cancer diagnosis for women who are under age 50 versus those that are above age 50,\u201d she said. \u201cThese are things that we are watching to try to understand.\u201d <\/p>\n A separate study published in January also found that breast cancer incidence rates among women ages 20 to 49 rose over the past 20 years. <\/p>\n The trend follows a pattern seen recently with other cancer types, such as colorectal cancer, in that more people are being diagnosed at younger ages than has traditionally been seen. <\/p>\n For the new report, researchers from the American Cancer Society, Weill Cornell Medicine and Harvard Medical School analyzed data on breast cancer incidence and deaths from the National Cancer Institute and registries at the US Centers for Disease Control and Prevention, dating to 1975. They found some significant differences in the data by race and state as well as age. <\/p>\n The researchers found that Black women continue to be more likely to die from the disease, as they had a 38% higher death rate than White women despite being 5% less likely to develop breast cancer. <\/p>\n \u201cIf you look actually more carefully at the mortality data, this is really driven by young women particularly,\u201d said Dr. William Dahut, chief scientific officer at the American Cancer Society. \u201cIf you look at Black women between the ages of 20 and 29, their chances of dying from breast cancer is two times greater than their White colleagues.\u201d <\/p>\n The data showed that Black women have the highest mortality rate overall. The rate ranged from about 12 deaths per 100,000 women in the Asian American\/Pacific Islander community to about 27 deaths per 100,000 in the Black community. <\/p>\n The report notes that Asian American and Pacific Islander women had the fastest increase in breast cancer incidence each year both among those younger than 50, at 2.7% per year, and in women 50 and older, at 2.5% per year. <\/p>\n \u201cThe acceleration of breast cancer incidence rates among Asian American and Pacific Islander is particularly disturbing. Emerging data suggest that some gene mutations predisposing to breast cancer may result in greater risk among Asian women compared to White women,\u201d Dr. Ruth Carlos, a professor of radiology and the assistant chair for clinical research at the University of Michigan, who was not involved in the new report, wrote in an email. <\/p>\n \u201cIt is disappointing that outcomes appear static for Black\/African-American women,\u201d she added. \u201cSeveral research groups are investigating the biological effects of structural discrimination on the development of breast cancer.\u201d <\/p>\n Some geographic variation also emerged in the data. The researchers found that the incidence of breast cancer ranged from 113 cases out of every 100,000 women in Nevada to about 143 per 100,000 in North Carolina. <\/p>\n Another geographic gap was found for the breast cancer death rate, ranging from about 15 deaths per 100,000 women in Massachusetts to about 23 per 100,000 in Mississippi and 24 per 100,000 in the District of Columbia. <\/p>\n \u201cDifferences by state reflect several factors, including demographic characteristics and the prevalence of cancer risk factors, mammography screening, and access to care, which is influenced by public health policy, such as the expansion of Medicaid, and other laws and programs,\u201d the researchers wrote. <\/p>\n They project that this year, nearly 311,000 cases of invasive breast cancer will be diagnosed among US women, affecting about 1 in 8, and more than 42,000 women will die from breast cancer. <\/p>\n The researchers <\/strong>should be \u201ccommended\u201d for such a comprehensive analysis of breast cancer trends, Carlos said. <\/p>\n \u201cThey have uncovered worrisome trends especially regarding breast cancer in younger women,\u201d she wrote. \u201cEnvironmental risks, lifestyle risks and genetic risk factors may be contributing to this rise.\u201d <\/p>\n The data in the new report reflects what many oncologists are noticing on the ground, said Dr. Carmen Calfa, a medical oncologist at the University of Miami Health System\u2019s Sylvester Comprehensive Cancer Center and associate director of Sylvester\u2019s community breast cancer outreach program, who was not involved in the new report. <\/p>\n \u201cThe alarming increase in incidence overall of breast cancer has been noticed and noted, and we see it in the office every day when we see patients of all ages, but we see more of the young ones than we used to,\u201d Calfa said, adding that her youngest breast cancer patient was diagnosed at 20. <\/p>\n \u201cWe\u2019ve been witnessing and seeing patients presenting to us at the higher rate, at the younger age,\u201d she said. \u201cWhile we\u2019re noticing the increase in incidence of breast cancer in younger patients, the trends have been really significant and consistent throughout other cancer types, and that makes us wonder, it\u2019s not only a breast-specific finding.\u201d <\/p>\n Calfa added that many of the risk factors for breast cancer are common throughout other cancer types as well, which may hold clues as to why the incidence of certain cancers continues to rise among younger ages. <\/p>\n \u201cThe common risk factors are all there, and I think that\u2019s where we have a huge opportunity,\u201d she said. \u201cThat\u2019s the lifestyle that includes the food, the type of diets, the amount of exercise.\u201d <\/p>\n Other factors that can raise the risk of breast cancer include having a family history of cancer, increased alcohol consumption, having a high-risk lesion biopsied from the breast or having a certain genetic mutation. <\/p>\n Some ways to reduce the risk of breast cancer include keeping a healthy weight, being physically active, drinking alcohol in moderation or not at all and, for some people, taking medications such as tamoxifen and breastfeeding your children, if possible. <\/p>\n \u201cI would also call to action for every woman and man to try to understand their own, personal risk and to be their best advocates when it comes to prevention, early detection, treatment and ultimately overall outcomes,\u201d Calfa said. <\/p>\n<\/p>\n
