Breast cancer is one of the most common cancers in women. But did you know that your personal care items can also put you at risk? Read on to know the experts' opinion on it.

Breast cancer is one of the leading causes of death worldwide. Having proper awareness about it is an important factor in its detection and timely treatment. Did you know that your cosmetics, daily personal care products can also put you at risk of breast cancer? There are many other toxins in the environment that can cause tumors to develop in women. While genetic predisposition and lifestyle factors are well-established contributors to breast cancer, Dr. According to Karisma Kirti, consultant breast specialist and oncoplastic surgeon, the role of environmental toxins is being recognized as a critical factor in the rising rates of breast cancer. These toxins, which include chemicals found in industrial byproducts, pesticides, plastics and some personal care products, disrupt hormonal balance, damage DNA and promote the development of cancer.

How do environmental toxins threaten breast tissue?

Environmental toxins include a wide range of chemicals, including endocrine-disrupting chemicals (EDCs), carcinogens, and other toxins. EDCs, in particular, are of great concern because they can mimic or interfere with the body's natural hormones, particularly estrogen. Estrogen plays an important role in the development of breast tissue, and prolonged exposure to estrogen or estrogen-like substances increases the risk of breast cancer.

One of the most studied environmental toxins is bisphenol A (BPA), a chemical used in the production of plastics and resins. Containers made with this chemical can leach BPA into food and beverages, leading to widespread human contamination. Research has shown that BPA can mimic estrogen and bind to estrogen receptors in breast tissue, leading to cell proliferation and cancer development. A study published in Environmental Health Perspectives found that BPA exposure is associated with an increased risk of breast cancer, especially when exposure occurs during critical periods of development such as puberty.

Pesticides, which are widely used in agriculture, are another important source of toxins in the environment. Some pesticides, such as organochlorines, are classified as probable human carcinogens. These chemicals persist in the environment and accumulate in fatty tissue, including breast tissue. A 2016 study examined levels of organochlorine pesticides in women with breast cancer and found significantly higher levels compared to controls, suggesting that these chemicals may be linked to the onset and progression of breast cancer.

How can shampoo, cosmetic products cause breast cancer?

Phthalates and parabens, used as preservatives in cosmetics and personal care products, are also implicated in breast cancer risk. Both EDCs are known and have been detected in human breast tissue. Phthalates, used in products such as shampoos, lotions and perfumes, have been shown to disrupt the endocrine system and may increase the risk of breast cancer by altering the expression of genes involved in hormone regulation, Dr. Kirti explained.

Similarly, parabens, used as antimicrobial agents in cosmetics, have been found in breast tumors. A study published by Darbre et al. Parabens have been found in the breast tissue of women with breast cancer, raising concerns about their role in the development of the disease. While the exact mechanisms are still under investigation, the presence of these chemicals in breast tissue suggests that they may contribute to carcinogenesis.

There is growing evidence linking environmental toxins to rising breast cancer rates in women. While more research is needed to fully understand the mechanisms and extent of risk, existing studies highlight the importance of reducing exposure to these harmful substances.

Individuals can take steps to reduce their exposure by choosing products free of harmful chemicals, supporting organic farming, and advocating for clean air and water.
