Breast Cancer Awareness Month 2019: Do Parabens Cause Breast Cancer? Here’s the TRUTH!

Most cosmetic and skincare products these days charge a premium for the "paraben-free" label. Consumers sift through products on supermarket shelves to ensure that the cosmetics they are not using contain chemicals. Parabens are preservatives that are added to cosmetic products to prevent bacteria and other pathogens from growing. About 85 percent of products such as shampoos, creams and lotions contain these chemicals. But why so much parabens fear? The panic that followed the 2004 research led to the association between cancer and cancer after being detected in breast tissue. But the cosmetic industry is insistent that parabens are safe. So does paralysis actually cause cancer? During running Breast Cancer Awareness Month 2019, let's uncover the truth.

Parabens and Estrogen

Breast cancer is an estrogen dependent disease. About 70 percent of them are sensitive to the hormone estrogen. Parabens such as methylparaben, propylparaben and butylparaben are known to have "oestrogenic activity", meaning that they behave like oestrogens in the human body.

Exposure to parabens, therefore, worries scientists contributing to breast cancer risk who say that chemicals alter gene expression and accelerate breast cancer cells.

After the 2004 study Journal of Applied Toxicology, In which parabens were found in 18–20 tumor samples, leading cosmetic companies decided to ban parabens from their cosmetic products.

Does Parabens cause breast cancer?

Although the 2004 study is telling, the cosmetic industry argues that parabens are completely safe for use. Furthermore, the presence of parabens in breast tissue in the study does not necessarily indicate that they are the cause of breast cancer. The Nation Cancer Institute said that the study's authors do not go in search of ultraviolet in other tissues of the body. It is also important to note that scientists could not find where the parabens came from.

While they penetrate the skin, less than one percent of unmetabolised parabens are available for absorption. And when they mimic estrogen, parabens are 10,000–100,000 times less potent than human estrogen according to the CDC.

So the jury is still out on whether they are actually the cause of breast cancer. Studies are mostly conflicting, but, if you want to be on the safe side, avoiding parabens will be your best bet. But paraben-free products will not necessarily protect you from other health problems. Companies can opt for paraben options whose health hazards have not yet been documented.
