American Cancer Society begins 30-year study of 100,000 black women's case and death rates

The American Cancer Society "has begun an ambitious, far-reaching study focusing on a population that has long been overlooked, despite high rates of cancer and cancer-related deaths: black women." 

That's the lead of a story by Roni Caryn Rabin in recent editions of The New York Times on an initiative called VOICES of Black Women that noted it's "believed to be the first long-term population study of its size to zero in specifically on the factors driving cancer prevalence and deaths among black women."

Researchers plan to enroll black women without cancer, ages 25 to 55, in D.C. and 20 states where most black women live.

Black women, the story says, have the highest death rates and lowest survival rates for many cancers of any racial or ethnic group. They die of uterine cancer at twice the rate of white women, and are "twice as likely to be diagnosed with stomach cancer and more than twice as likely to die of it," Rabin's piece notes. "They are also 40 percent more likely to die of breast cancer."

Racial disparities in breast cancer are relatively new. The Times story quotes Dr. Alpa Patel, senior vice president of population science at the ACS and co-principal investigator of the VOICES study, as saying that "until the 1970s, there was no disparity in breast cancer outcomes between black and white women. We know now there are more aggressive tumors, especially at younger ages in black women compared to white women, and we don't fully understand why."

Women in the study will be surveyed on their use of personal care products, "including hair straighteners, which have been implicated in some cancers," the article reports. In addition, researchers "will track stressors related to the physical environment, and facts such as neighborhood walkability, crime, air pollution, access to healthy food, and proximity to liquor stores and establishments that sell cigarettes."

Because of uptick in cancers following pandemic, physicians are now asking if covid is to blame

A rise in cancers after the pandemic has been causing doctors to study whether Covid-19 is at fault.

A story by Ariana Eunjung Cha in editions of The Washington Post recently indicated that the "uptick in aggressive, late-stage cancers since the dawn of the pandemic is confirmed by some early national data and a number of large cancer institutions."

The article goes on to say that although "the idea that some viruses can cause or accelerate cancer is hardly new, [since] scientists have recognized this possibility since the 1960s, today researchers estimate 15 to 20 percent of all cancers worldwide originate from infections agents such as HPV, Epstein-Barr, and hepatitis B."

It will "probably be many years before the world has conclusive answers whether the coronavirus is complicit in the surge of cancer cases," Cha's story continues, but "concerned scientists are calling on the U.S. government to make this question a priority knowing it could affect treatment and management of millions of cancer patients for decades to come."

Douglas Wallace
The story quotes Douglas C. Wallace, a University of Pennsylvania PhD geneticist and evolutionary biologist, to the effect that "we are completely under-investigating this virus. The effects of repeatedly getting this throughout our lives is going to be much more significant than people are thinking."

Cha's piece also quotes David Tuveson, director of the Cancer Center at Cold Spring Harbor Laboratory and ex-president of the American Association for Cancer Research, as saying that "a number of small and early studies — many of which have been published within the past nine months — suggests that coronavirus infection can induce an inflammatory cascade and other responses that, in theory, could exacerbate the growth of cancer cells."

Covid "wrecks the body, and that's where cancers can start," he said, "explaining how autopsy studies of people who died of covid-19 showed prematurely aged tissue."

The story notes further that a paper "published in 2023 in the journal Biochimie explored mechanisms the coronavirus could exploit to aggravate several forms of cancer, including lung, colorectal, pancreatic, and oral."
