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

by

4. Cleaning Products 🧽

What’s the Risk?

That shiny kitchen counter might come at a hidden cost. Many cleaning sprays and detergents contain formaldehyde, ammonia, and 1,4-dioxane, substances flagged by EPA and OSHA for potential carcinogenic effects.

Constant exposure, especially in poorly ventilated areas, increases risks over time.

What to Do Instead

  • Choose eco-friendly cleaning brands.
  • DIY natural cleaners: vinegar + baking soda + lemon work wonders.
  • Always ventilate while cleaning.

5. Candles (Especially Paraffin-Based) 🕯️

What’s the Risk?

Candles create a cozy atmosphere, but paraffin-based ones may release toluene and benzene when burned—both are known carcinogens.

Fragrance oils used in some candles can also contain synthetic chemicals that pollute indoor air.

What to Do Instead

  • Choose beeswax or soy candles with cotton wicks.
  • Use natural essential oils for fragrance.
