Let's eliminate the environmental exposures linked to breast cancer to stop this disease before it starts. Learn more and join us at www.bcpp.org!

We are the leading science-based policy and advocacy organization working to prevent breast cancer by eliminating our exposure to toxic chemicals and radiation. Our focus is on the intersection of breast cancer prevention and environmental health. We've published 30+ scientific reports and passed 15 laws to improve the health of people and the planet.

In the same week that Bayer, the company that makes the w**d killer Roundup, proposed a seven billion dollar settlement to cancer patients — because it was clear enough that their product was linked to this disease — the Trump administration just announced an effort to boost the production of glyphosate.

Glyphosate is the main chemical in Roundup, and the very one that is causing cancer.

This just shows that the government is not using science to protect our health from toxic chemicals in the environment.

That’s why we need organizations like BCPP to fight for regulation to protect us all.

☕ Your tea might be serving you billions of plastic particles with every cup!

New research found that common teabags made from nylon, polypropylene, and even cellulose release HUGE amounts of tiny plastic particles when you steep them in hot water - we’re talking up to 1.2 BILLION nanoparticles per milliliter! 😱

Scientists tested what happens when these particles meet human gut cells and found they’re definitely getting absorbed. Different types of plastics were taken up by different types of intestinal cells, showing our bodies are interacting with these materials in ways we don’t fully understand yet.

This isn’t just about ocean plastic - it’s in our kitchen, in our tea, and in our bodies. The health effects? Still being studied, but this is a wake-up call that everyday products we consider safe might be exposing us to much more plastic than we thought.

🌿 It’s time to switch to loose leaf tea—there’s a wide variety of tea leaf sieves to choose from—until companies prove their teabags are plastic free.

Consumer Reports Advocacy’s recent article on toxic chemicals hiding in everyday cosmetics reinforces what we've been saying for years.

From phthalates in fragranced products to PFAS in "long-lasting" makeup, formaldehyde-releasers in hair straighteners to parabens in lotions, too many beauty products contain harmful ingredients linked to breast cancer, reproductive harm, and hormone disruption.

✨ Swipe to see how to identify and avoid 5 of the most concerning chemicals and 5 tips to shop safer.

Women of color face disproportionate exposure to these toxic chemicals through products explicitly marketed to them. This isn't just about ingredients—it's about beauty justice.

We've been fighting for safer cosmetics for years through our Campaign for Safe Cosmetics. While we wait for stronger federal regulations, you can protect yourself by voting with your wallet and demanding better from brands.

Phthalates, common chemicals used in plastics, personal care products, food packaging, and much more may drive breast cancer—now the leading cause of cancer death among women ages 20-39, according to a study from the University of Miami Leonard M. Miller School of Medicine.

❌ The research suggests that phthalates interfere with the body’s hormone systems, activate cancer-promoting genes, and make tumors both easier to form and harder to treat.

❌ The review also points out that while EuropeanCommission has restricted several phthalates from all uses, the U.S. has only banned a handful and still allows phthalates in most food packaging and personal care products.

🏛 Luckily, there is action to take! Building on the success of BCPP’s historic California Toxic-Free Cosmetics Act (AB 2762), we’re pushing for passage of the Safer Beauty Bill Package, a federal legislative package aimed at making personal care products safer for everyone, especially women of color and professional salon workers.

Researchers from UCSF and the University of Sydney assessed studies of the health effects of microplastics on human digestion, respiration, and reproduction. Their findings identify microplastic as a suspected hazard that may interfere with human biological processes.

🫁 Evidence was found linking microplastic to changes in animal intestines, possible lung tissue damage, and breathing impairment.

Furthermore, evidence of chronic inflammation, immune suppression, & oxidative stress in the colon and lungs from microplastic suggests it could contribute to cancerous malignancies in these organs.

🤰 In regard to reproduction, and based on previous work with animals, researchers also suspect that microplastics disrupt reproductive hormones, ovulation, and s***m count.

Not only that, but early studies suggest microplastic may pose risks to the placenta, maternal health, and health of the child.

🔬An unrelated and recently published study of cancer patients in Algeria found high concentrations of microplastics in breast cancer tissues (and colon and re**al tissues).

⚠️ Although UCSF and University of Sydney researchers are quick to note that more study is needed, they emphasize practicing precaution in the meantime because plastic is ubiquitous in contemporary life, and exposure to it is constant.

Let’s take a moment to celebrate a win!

In 2020, co-sponsored Senate Bill 1044 to ban the manufacture, sale, and use of firefighting foam that contains PFAS, otherwise known as forever chemicals. Click 🔗 in bio to read the press release.

This was a big step toward better protecting our firefighters, who experience higher rates of cancer than the general population due, in part, to exposure to PFAS in gear, firefighting foam, dust, and smoke on the job. This is especially true for female firefighters.

Then, in May 2024, San Francisco passed an ordinance to ban PFAS in firefighter uniforms, too! San Francisco is now the largest city in the country to equip firefighters with new gear free of forever chemicals. BCPP is proud to have contributed to the momentum toward this success and to a safer reality for SF firefighters.

There are few things cozier than a hot cup of tea...but we now know that the majority of commercial tea bags, when steeped, release billions of particles of microplastics into our tea. Not so cozy!

⚠️In fact, a recent study found that steeping a bag of tea in water at brewing temperature released approximately 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup. That’s much higher than plastic loads released from other foods.

Exposure to microplastics has also been linked to increased breast cancer risk, Type 2 diabetes, coronary heart disease, and stroke.

Celestial Seasonings, one of the largest tea companies in the world, is on its way to plastic free outer packaging, but hasn’t yet addressed its tea bags, where plastic exposure matters the most!

📢That’s why we’re asking Celestial Seasonings to make its tea safer by eliminating plastic from its tea bags.

Do you want your tea microplastic-free? Join us and take action today.

“As the daughter of a cancer survivor, I’ve seen firsthand how one’s environment can dictate one’s risk for the disease – even with the utmost of care. For me, prevention means accountability for those in power to provide a safer tomorrow for ourselves and our loved ones.

The amount BCPP has accomplished across multiple arenas is astounding. How many other organizations can boast dozens of laws passed year over year? How many other organizations can claim that they take major corporations to task and invoke change? All the while, how many can do so while creating advocates and partners at a national scale? In short, BCPP has a history entrenched in results.”

The truth is, breast cancer risk isn’t just about genetics. Whether you carry a hereditary risk or not, we’re all exposed to everyday toxics that increase our chances of developing this disease. That’s why BCPP’s work can’t wait.

Your gift right now does double the work. During our Year-End Match, every dollar you donate is matched dollar-for-dollar—meaning twice the research, twice the advocacy, twice the protection for families everywhere.

We have just days left to reach our $100,000 goal and unlock the full match. https://donate.bcpp.org/campaign/741538/donate?c_src=social&c_src2=FB
