Cancer From Chemicals? These Household Products Are Known Carcinogens

We all know to avoid smoking, excessive alcohol use, and tanning bed exposure to lower our cancer risk, but we may not realize the everyday products we use could be every bit as dangerous to our health. From the dryer sheets used in our laundry to cleaning solutions for wiping our cabinets, certain household items contain ingredients that are known carcinogens.

You should always feel safe in your home, so take a look at this list of household products that are known carcinogens. We suggest eliminating them from your home immediately.

1. Air fresheners

Be wary of your air freshener. |

When your house or apartment has a rancid odor, you might be used to grabbing air freshener. While they’re a staple in many American households, conventional air fresheners are a hotbed of substances that can leave you or a loved one in your house very ill. In a 2008 study published in the journal Environmental Impact Assessment Review, researchers tested six products for toxic chemicals, three of which were air fresheners. They found five of the six products tested emitted one or more carcinogenic chemicals.

2. Cleaning products

Products that are keeping your house clean can also contain carcinogenic substances. The Environmental Working Group has a Cleaners Hall of Shame list with the worst offenders. In the Group’s Guide to Healthy Cleaning, they found nearly three-quarters of the 2,500 cleaning products listed contain ingredients that can harm respiratory health, and over one-quarter contain carcinogenic ingredients. If you want to know exactly what ingredients are added, it may be tough for you to find out — half of all products scored low in regards to ingredient disclosure.

3. Dryer sheets

Thanks to the olfactory magic of fabric-softener sheets, warm laundry has become as comforting as ever. They’re a simple product made to soften fabric fibers and give your clothes that irresistible scent. However, the fragrances could pose health risks, as toxins can permeate those sheets and transfer from your clothes to your skin.

In a larger study conducted by the same team we mentioned before, 25 scented household products were tested for hazardous chemicals. Nearly half of all the products tested generated at least one carcinogenic air pollutant, and various brands of dryer sheets were tested in this study.

4. Pesticides

If you have trouble growing fruits and veggies in your garden because of weeds, insects, or small animals, you’ve probably used soil containing pesticides to help your produce grow. Pesticides ward away the living things that can sabotage your summer crops, but they’re also carcinogenic. A growing number of studies are finding evidence pesticides used for home gardening are associated with increased cancer risk.

5. Food dye

Food dyes are everywhere. |

While not a household product itself, food dye is found in nearly every processed food, drink, vitamin, and dietary supplement found in your home. Studies have shown nine types used in the U.S. could be carcinogenic. Use of these dyes has increased fivefold in the U.S. since 1955, and the Center for Science in the Public Interest published a summary on what they found when testing various food dyes. It’s first important to note the studies were performed on rodents and lasted for two years, so we have yet to understand exactly how humans could be affected over a longer period of time.

6. Pet flea collars

Be careful of what you’re putting on your pets. |

You’re not cleaning your house with this product, but if you have a pet that ventures outdoors, we’re betting it has a flea collar. According to SFGate, the U.S. Environmental Protection Agency considers two chemicals found in some varieties of these collars to be carcinogens — propoxur and tetrachlorvinphos. Not only are these chemicals potentially cancer-causing, but they can also cause neurological damage to children.

7. Facial moisturizers

Moisturizing every day is essential for good skin care, but many facial creams contain known carcinogenic chemicals — parabens. Livestrong says these common preservatives are used in foundations, cosmetic creams, and anti-aging products of all kinds. While parabens help to prevent bacterial growth and yeast from forming in your favorite products, the European Commission on Endocrine Disruption has listed these chemicals as category 1 substances known for their endocrine disrupting capabilities. These disruptions can potentially cause tumors or other disorders.

Because parabens have been detected in breast cancer tumors, a lot of people suspect a link to cancer. According to WebMD, parabens can actually mimic estrogen, which is of particular concern because excess estrogen can drive tumor growth.

8. Laundry detergent

We all want clean clothes, but your detergent likely harbors a chemical called 1,4-dioxane, and it isn’t just found in laundry detergent — it’s in automotive coolant liquids, cosmetics, bath products, and even in the air we breathe. Studies show animals exposed to this chemical during their lives were at a much higher risk of developing cancer. While there is little information regarding how humans fare when exposed to 1,4-dioxane over a lifetime, the Department of Health and Human Services and the Environmental Protection Agency consider the chemical a likely carcinogen.

9. Nail polish

Men may not have to worry too much about this potentially cancer-causing product, but women who love to paint their nails may want to think twice about the kind of nail polish they use. Many nail polishes contain formaldehyde, which the Occupational Safety and Health Administration says can raise cancer risks. Formaldehyde can also be found in nail disinfectant tools used in salons, so you may have an even higher risk of exposure if you pay to get your nails done instead of painting them yourself..

10. Incense

Incense may smell great, but it could be carcinogenic. |

If your favorite way of removing unpleasant odors in the house is by lighting incense, you may be harming your health. A review about the safety of candles and incense concluded these products are likely carcinogenic. Some of the research cited an increased risk of cancer in children whose parents burned incense during pregnancy or while nursing. Though one study included found the burning of incense was associated with a decreased chance of developing lung cancer, the authors think societal factors played a role.
