New research suggests that there is a correlation between exposure to certain chemicals while in the womb that may increase the chance of developing breast cancer as an adult, reports DailyTech
Some chemicals, which can be found in the plastic used for water bottles, can interrupt how hormones function in the human body. They can also cause negative effects in the immune, reproductive and neurological systems of humans, reports the source.
Researchers conducted the tests by treating pregnant mice with these chemicals. They observed the adult offspring of the rodents and found that they were producing high levels of a certain enzyme that, when found in humans, ensures a diagnosis of breast cancer.
"These results show that all estrogens, even weak ones can alter the development of the breast and place our children at risk," Professor Hugh S. Taylor, one of the researchers of the study, told the news source.
Researchers are once again raising concerns about the need to monitor women who are pregnant and may be exposed to certain chemicals in the environment.
The American Cancer Society (ACS) estimates that over 190,000 women were diagnosed with breast cancer in 2009.
