BPA and Phthalates Linked to Head and Neck Cancer

BPA and diethyl phthalate are now linked to head and neck cancer. Researchers found that these everyday plastic chemicals activate the same cancer-driving pathway.

What the Study Found

A 2026 study in Ecotoxicol Environ Saf combined computational and experimental analysis to identify how BPA and diethyl phthalate promote cancer. Both chemicals activate the MEK signaling pathway, a known driver of tumor growth in head and neck cancers.

Head and neck cancers include cancers of the mouth, throat, sinuses, and salivary glands. They're among the most common cancers worldwide, and environmental chemical exposure may be contributing to the rising rates.

Where These Chemicals Come From

BPA is in food can linings, plastic containers, and thermal receipts. Diethyl phthalate is in fragrances, cosmetics, and personal care products. You're exposed to both every day through food, skin contact, and inhalation.

What You Can Do

Choose fragrance-free products. Avoid canned foods and plastic food containers. Use glass and stainless steel. Check labels for phthalates and bisphenols.
