‘Alarming’ growth of breast cancer under 40 years old in the SH.BA

The rate of breast cancer in young women is increasing a nationwide trend that researchers call “alarming”.

But a new study by the Columbia University’s Public Health School revealed significant geographical differences, with New York, New Jersey and Connecticut among the five states with the highest breast cancer rates in women under 40.

Researchers say findings can refine efforts to identify groups at higher risk for the disease.

“The incidence of breast cancer is growing in American women under 40, but so far, it was unknown if the incidence trends changed from the American geographical region,” the first author and professor of epidemiology told the post. Columbia Mailman, for the mail.

“Our findings can more accurately inform whether exposures that change to the prevalence throughout the US also contribute to the risk of breast cancer to young women.”

Using the US cancer statistics database, researchers analyzed breast cancer incidence levels regulated by age in women aged 25-39 from 2001 to 2020.

They found that the level of breast cancer in women under 40 increased by more than 0.50% per year in 21 countries, while remained stable or declining in others.

The western region had the highest growth level from 2001 to 2020. Northeast had the highest absolute level among women under 40 and without significant increase over time. The south was the only region where cases of breast cancer under 40 did not increase over the 29-year period.

The overall incidence of early start breast cancer ranged from 28.6 per 100,000 to Wyoming in 41 cases per 100,000 in Connecticut.

The five countries with the highest incidence of early early start from 2001 to 2020 were Maryland, New York, New Jersey, Hawaii and Connecticut.

What is happening in the three-state area?

Short Answer: They are still realizing it.

“While our study did not examine the fundamental causes of these geographical differences in the incidence of early early breast cancer, our findings highlight the need for further research on the factors that run this increase,” Kehm Post told.

“For example, our group is currently investigating the role of environmental chemical exposures and living behaviors, such as physical inactivity and excessive drinking, about early onset breast cancer,” she added.

Alcohol consumption is a well -created risk factor for breast cancer, with research showing that the more women drink, the higher their chances of developing the disease.

Studies suggest that women who have a drink a day face a risk of 7% to 10% higher than non-peaches, while those who consume 2 to 3 drinks daily have about 20% increased risk, according to the breast cancer search foundation.

Alcohol consumption differs significantly from the state, formed by local drinking culture, laws, policies, urban-rural changes and demographic and socio-economic factors. New Hampshire, Delaware, Nevada, North Dakota and Montana top the list of per capita alcohol consumption, according to the national drug line.

Is something in the water?

Environmental factors can also play a role, although experts still determine what that role may be.

“We have explored how environmental exposures during childhood and early adolescence can affect early onset of breast cancer and relationships with environmental exposure and breast cancer risk has been more stable in young women,” Mary Beeth Terry, senior author and professor of epidemiology at Columbia Mailman Public Health School, told The Post.

“More research, as well as interference, especially in the NYC area, to reduce the long inequalities of breast cancer health we see with more aggressive cancers seen in younger women, especially young women with color, , ”she added.

The study found that Hispanic women had the lowest level of early breast cancer in all regions, ranging from 26 to 100,000 to Midwest to 32.6 per 100,000 northeast.

Non-Hispanic white women were the only group that suffered a statistically significant growth in the incidence of early early breast cancer in all four US regions.

Meanwhile, non-Hispanic black women had the highest incidence of early early breast cancer, a trend that is seen across the country.

“Increasing the incidence we are seeing is alarming and cannot be explained only by genetic factors, which evolve at much longer periods nor by changes in review practices given that women under 40 are under recommended age for routine mammography examination, ”Kahm said.

Be controlled

The US Task Force recommends that all women start breast cancer appearances every two years starting at age 40.

The group updated its recommendation last year, as they previously said women could choose to start a 40 -year -old breast cancer examination, with a stronger push for two -year exams aged 50 to 74.

The measure towards previous shows is partly in response to an increase in the number of breast cancer cases in young women. The incidence rate for those under 50 has increased by about 1.4% per year, overcoming the increase in cases among older women, according to the American Cancer Association.

While the level of death from breast cancer has fallen thanks to improved treatments, it still remains the second most common cause of cancer death among American women. In 2025, the American Cancer Society estimates that 316,950 new cases will be diagnosed in women, with 42,170 expected to die from the disease.
