Breast cancer among young women increasing more than genetics or population growth allows for
From my own extensive research, breast cancer seems to be around 1% genetic and 99% caused by diet, lifestyle and environment.
It is why the term for breast cancer in some Asian cultures is translated as “rich women’s disease”.
What has this latest analysis found?
- The rate of advanced breast cancer for U.S. women aged 25-39 nearly doubled from 1976 to 2009
- In 1976, 1.53 out of every 100,000 American women 25-39 years old was diagnosed with advanced breast cancer
- By 2009, the rate had almost doubled to 2.9 per 100,000 women
- The fastest increase of breast cancer in younger women occurred in the most recent era from 2000-2009, at 3.6% increase per year
- Cases of younger women with advanced breast cancer have increased about 2% each year since the mid-1970s
- They have been increasing every year for almost three decades
- Metastatic presentation rose as a proportion of all invasive breast cancer in the 25-39 age group, from 4.4% in the 1970s to 7.2% after the year 2000
- The breast cancer growth in younger women was seen among all races and ethnicities and urban and non-urban areas alike
- The increase was statistically significant and was worrisome because it involved cancer that had already spread to organs like the liver or lungs by the time it was diagnosed, which greatly diminishes the odds of survival
What did the researchers say is responsible for this growth in breast cancer?
“…lifestyle changes, obesity rates, changes in alcohol and tobacco use, diet, exercise, earlier onset of menstruation (mostly caused by diet), use of birth control, delayed pregnancy and other factors…”
Study by Johnson RH, et al as “Incidence of breast cancer with distant involvement among women in the United States, 1976 to 2009” as published in the Journal of the American Medical Association JAMA 2013; 309: 800-805. Rebecca Johnson examined registries and information from 936,497 women who had breast cancer from 1973-2009, 1992-2009 and 2000-2009. This data was from the National Cancer Institute and from the U.S. Surveillance, Epidemiology and End Results (SEER), and published on Wednesday February 27, 2013.
