10 Innocent-Looking Household Items That Can Cause Cancer (Backed by Science)

What’s the Risk?

Non-stick cookware is a favorite in many homes because it makes cooking and cleaning easier. However, many pans have been coated with perfluorooctanoic acid (PFOA), a chemical that the American Cancer Society has associated with kidney and testicular cancer.

When overheated, these pans may also release toxic fumes, raising long-term health concerns.

What to Do Instead

Switch to safer alternatives like:

  • Stainless steel (durable and non-toxic)
  • Cast iron (naturally non-stick when seasoned properly)
  • Ceramic-coated pans (a safer, easy-to-clean option)

2. Air Fresheners 🌬️

What’s the Risk?

That “fresh” scent from plug-in air fresheners or sprays often comes with a hidden cost. Many contain volatile organic compounds (VOCs) such as formaldehyde and benzene, both linked to cancer in long-term studies.

Prolonged exposure may affect indoor air quality and respiratory health, especially in homes with limited ventilation.

What to Do Instead

  • Ventilate naturally by opening windows.
  • Use essential oil diffusers made with organic oils.
  • Add indoor plants, which naturally help filter the air.

3. Plastic Food Containers (Especially When Heated) 🥡

What’s the Risk?

Not all plastics are created equal. Containers labeled with #3 (PVC), #6 (PS), and #7 (polycarbonate) can leach harmful chemicals, including bisphenol A (BPA). Studies have linked BPA exposure to breast and prostate cancers.

 

Heating plastic in the microwave accelerates this chemical leaching process, making it even riskier.

What to Do Instead

  • Use glass or stainless steel food containers.
  • If you must use plastic, look for BPA-free options.
  • Never microwave food in plastic.
