Can chemicals in household products increase endometrial cancer risk?

What's actually in it

Endocrine-disrupting chemicals (EDCs) are in plastics (bisphenols, phthalates), personal care products (parabens, UV filters), pesticides (organochlorines, atrazine), and nonstick coatings (PFAS). These chemicals mimic or block estrogen and progesterone, two hormones that control the growth of the uterine lining.

Endometrial cancer is the most common gynecological cancer in the US, and rates have been rising for two decades. Excess estrogen stimulation is a known risk factor.

What the research says

A 2026 systematic review in Environ Health Perspect gathered the epidemiological evidence linking EDC exposure to endometrial cancer. The review found consistent associations across multiple chemical classes.

Cadmium (a metallic estrogen mimic found in food and cigarette smoke) showed the strongest link. Women with higher cadmium levels had an elevated endometrial cancer risk. Organochlorine pesticides like DDT residues, which persist in the food supply decades after being banned, also showed positive associations.

Bisphenols and phthalates from plastic products stimulated endometrial cell growth in lab studies, consistent with their estrogen-mimicking effects. PFAS showed emerging evidence of association, though the data was less extensive.

The review emphasized that most people are exposed to all of these chemicals simultaneously, and their combined estrogenic effects may be stronger than any single chemical alone.

Reducing total EDC exposure through glass food storage, fragrance-free products, organic produce, and PFAS-free cookware can help lower one modifiable risk factor for this rising cancer.
