5 Simple Ways To Avoid Exposure To Cancer-Causing Chemicals In Your Home

1.

Upgrade to non-toxic cosmetics and personal care products 

Chemicals found in cosmetics and personal care products that can raise our cancer risk include heavy metals2, formaldehyde3, phthalates4, parabens5, 1,4-dioxane6, and PFAS (per- and polyfluoralkyl substances, a.k.a. “forever chemicals”).

Some of these chemicals, like parabens, may show up on ingredient lists, but others aren’t always listed. For example, formaldehyde often isn’t listed, but it can be released when other chemicals commonly found in hair products combine and are heated during styling. When “fragrance” shows up on an ingredient list, that product possibly contains dozens of unlisted chemicals (including phthalates, which can be used to make fragrance linger on our skin and hair for longer periods of time).

Thankfully, there are a number of third-party organizations that verify products as nontoxic and free of harmful ingredients, including the Healthy Living App, MadeSafe, and Clearya. 

You don’t have to throw away all of your products and start over. This process is less daunting if you wait until you’re about to run out of something like shampoo, hand cream, or mascara, and use that as an opportunity to pick a new, nontoxic upgrade. 

2.

Eat organic whenever possible

Many of the pesticides used in the U.S. raise our risk of certain cancers, and research has found that people who eat more organic produce have lower levels of pesticides in their bodies7. 

Eating fully organic can be pricey, so it can be helpful to prioritize fruits and veggies that are most likely to absorb pesticides, including strawberries, leafy greens, peaches, pears, nectarines, apples, grapes, bell and hot peppers, cherries, blueberries, and green beans.

Crops that are least likely to absorb pesticides include avocados, sweet corn, pineapple, onions, papaya, frozen sweet peas, asparagus, honeydew melon, kiwi, cabbage, mushrooms, mangoes, sweet potatoes, watermelon, and carrots.

Stop heating food in plastic 

A 2021 study8 by researchers in Switzerland identified more than 10,000 chemicals used in plastics manufacturing, and found that about a quarter of them are “substances of potential concern,” for endocrine disruption, reproductive harm, organ damage, cancer, or environmental toxicity. 

More than half of the chemicals the researchers identified as potentially concerning are unregulated in the U.S., and 901 of those chemicals are approved for contact with food in the U.S. At least 1,000 of these concerning chemicals, including some carcinogens, are harmful even in very small doses. An additional 39% of the chemicals used in plastics manufacturing haven’t been studied enough to determine whether they’re hazardous, according to the study. 

When plastic containers are heated, toxic chemicals can leach into food and make their way into our bodies. When products are labeled “microwave safe,” that means they won’t melt or fall apart in the microwave—it does not necessarily mean they won’t leach toxic chemicals into food when heated. The same goes for things like plastic crockpot liners.

When heating food, I recommend sticking to glass, metal, or ceramic for this reason.

4.

Invest in a good water filter

Contaminants in tap water that can raise our cancer risk include PFAS, arsenic, disinfection byproducts, and hexavalent chromium. Many of these chemicals are unregulated in the U.S., and the Environmental Working Group estimates that more than 100,000 cancer cases in the U.S. are caused by carcinogens in tap water.

I recommend finding a water filter that can effectively remove the contaminants in your tap water. To make this easier, the Environmental Working Group has created a national tap water database where you can look up the contaminants in your region’s drinking water by zip code and learn which type of water filter works best to remove those specific contaminants.

Start filtering indoor air

Americans on average spend 90% of our time indoors, and carcinogens from our cleaning products, gas stoves, and outdoor air pollution can build up and linger in the air in our homes.

We can easily reduce carcinogens in the air in our homes by periodically running an indoor air filter. HEPA filters are best. HEPA systems can be expensive, but there’s an inexpensive DIY version that involves affixing HEPA filters to a box fan.
