Study Shows Hair Dyes & Chemical Straighteners May Cause Breast Cancer

Study Shows Hair Dyes & Chemical Straighteners May Cause Breast Cancer

A study of nearly 47,000 cancer-free women published in the International Journal of Cancer indicates that women who use hair dye and chemical hair relaxer/straighteners could be increasing their risk of breast cancer by up to 60%.

“If women are worried about their breast cancer risk, hair dyes and chemical straighteners may be one exposure they could avoid. However, hair is very important to many women.

Dr. Anne McTiernan, M.D., Ph.D.

Epidemiologist, Public Health Sciences Division at Fred Hutchinson Cancer Research Center in Seattle

Many hair products contain endocrine-disrupting compounds and carcinogens potentially relevant to breast cancer.


Do Hair Dyes Cause Cancer?

The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO). Its major goal is to identify causes of cancer. IARC has concluded that workplace exposure as a hairdresser or barber is “probably carcinogenic to humans,” based on the data regarding bladder cancer. (The evidence for other types of cancer is considered mixed or inadequate.)

The National Toxicology Program (NTP) is formed from parts of several different US government agencies, including the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). The NTP has classified some chemicals that are or were used in hair dyes as “reasonably anticipated to be human carcinogens.”

Are Hair Dyes Regulated?!

In the United States, the Food and Drug Administration (FDA) regulates the safety of cosmetics, including hair dyes, but there are limits on what the FDA can do. The FDA does not approve each ingredient used in hair dyes before it goes on the market, and in general the responsibility for the safety of products and ingredients falls to the manufacturers. Yes, the companies that make hair dyes self-regulate the safety of their own products.

  • The FDA can take action only AFTER cosmetics are proven harmful or in violation of the law (such as being mislabeled).
  • This only applies to new ingredients used in hair dyes as the older ingredients still in use in hair dyes were excluded when the FDA was given the power to regulate them.
  • If cosmetics (including hair dyes) or their ingredients are found to be unsafe, the FDA can request that the company recall the product, although it can’t require a recall.

So should I limit my exposure to hair dye?

Cancer.org says: more studies are needed to help clarify this issue.

Cancerzen.com says Yes! Yes, you probably should. But, if its that one thing you can’t do without – so be it. If you make every effort at clean living in the other areas of your life, you are well on your way. And eventually, there will be newer hair dye products that are vegetable based and less dangerous available.

Stay well!

Tamoxifen: prevents cancer. Also Tamoxifen: causes cancer.

Tamoxifen: prevents cancer. Also Tamoxifen: causes cancer.

How do you know what’s helping and what’s hurting?

My oncologist would tell me about medicines available to increase my odds in fighting or preventing cancer. Every option was weighed, and even a small increase was considered a must-have. But then later I’d read that the same drug that upped my odds 12% came with an 8% risk of causing a different cancer! That’s only a 4% net gain! Is 4% worth all of the misery and other possible side effects?! Ugh!

Tamoxifen is the one drug I fully refused. Several others I have taken were just as gnarly, but for me, I couldn’t throw the dice with Tamoxifen. Even at my last oncologist visit, it was suggested. Eight years out. Still not interested.

I will leave you the with this random collection of possible side effects. Everything below was directly copy and pasted from Tamoxifen’s official website.


Tamoxifen may cause cancer of the uterus, strokes, and blood clots in the lungs. These conditions may be serious or fatal.

If you experience any of the following symptoms during or after your treatment, call your doctor immediately: abnormal vaginal bleeding; irregular menstrual periods; changes in vaginal discharge, especially if the discharge becomes bloody, brown, or rusty; pain or pressure in the pelvis; leg swelling or tenderness; chest pain; shortness of breath; coughing up blood; sudden weakness, tingling, or numbness in your face, arm, or leg, especially on one side of your body; sudden confusion; difficulty speaking or understanding; sudden difficulty seeing in one or both eyes; sudden difficulty walking; dizziness; loss of balance or coordination; or sudden severe headache.

Keep all appointments with your doctor. You will need to have gynecological examinations regularly to find early signs of cancer of the uterus.

Tell your doctor if any of these symptoms are severe or do not go away:

  • increased bone or tumor pain
  • pain or reddening around the tumor site
  • hot flashes
  • nausea
  • excessive tiredness
  • dizziness
  • depression
  • headache
  • thinning of hair
  • weight loss
  • stomach cramps
  • constipation
  • loss of sexual desire or ability

Some side effects can be serious. If you experience any of the following symptoms, call your doctor immediately:

  • vision problems
  • loss of appetite
  • yellowing of the skin or eyes
  • unusual bruising or bleeding
  • fever
  • blisters
  • rash
  • swelling of the eyes, face, lips, tongue, throat, hands, arms, feet, ankles, or lower legs
  • thirst
  • muscle weakness
  • restlessness

Tamoxifen may increase the risk that you will develop other cancers, including liver cancer. Talk to your doctor about this risk. Tamoxifen may increase the risk that you will develop cataracts (clouding of the lens in the eye) that may need to be treated with surgery. Talk to your doctor about this risk.

Symptoms of overdose may include:

  • uncontrollable shaking of a part of the body
  • unsteadiness
  • dizziness

Hot flashes, night sweats, and vaginal dryness are common side effects of hormone therapy. Hormone therapy also disrupts the menstrual cycle in premenopausal women.

  • Risk of blood clots, especially in the lungs and legs
  • Stroke
  • Cataracts
  • Endometrial and uterine cancers
  • Bone loss in premenopausal women
  • Mood swings, depression, and loss of libido
  • Risk of heart attack, angina, heart failure, and hypercholesterolemia
  • Bone loss
  • Joint pain
  • Mood swings and depression

The most common side effects caused by tamoxifen are hot flashes; vaginal dryness, discharge, or irritation; and reduced interest in sex. These side effects are not usually serious, but they can be bothersome.

Other side effects are rare but are more dangerous. These include:

  • Overgrowth of the lining of the uterus (endometrial hyperplasia) and cancer of the lining of the uterus (endometrial cancer).
  • An increased risk of blood clots in the legs (deep vein thrombosis) and the lungs (pulmonary embolism). Changes in the blood’s ability to clot have been reported in patients receiving tamoxifen.
  • A small increased chance of stroke.
  • Ovarian cysts.
  • An increased risk of cataract formation and the need for surgery for cataracts.

Because tamoxifen can cause changes in the lining of the uterus, women who use it should have yearly pelvic exams and should be evaluated further if they experience any abnormal uterine bleeding. Tamoxifen may not work as well if a woman is also taking some types of medicine to treat hot flashes or depression. If you take tamoxifen, talk with your doctor about any other medicines you are taking.

If you are thinking about taking tamoxifen to reduce the chance that you will develop breast cancer, you should talk to your doctor about the risks and benefits of this treatment.

You and your doctor will decide whether the possible benefit of tamoxifen treatment is worth the risks of taking the medication. 🤷🏻‍♀️

EU approval of glyphosate weed killer based on ‘plagiarized’ Monsanto studies

EU approval of glyphosate weed killer based on ‘plagiarized’ Monsanto studies

Regulators in Europe were considering whether or not to continue to allow sales of Monsanto’s Round Up, a glyphosphate-based weed killer, in the EU. The European Food Safety Authority reviewed the assessment from Germany’s Federal Institute for Risk Assessment, and based on their findings in this report, they determined that glyphosphate was safe.

Turns out, the assessment provided by Germany was heavily plagiarized, literally copy-and-pasted from Monsanto’s own agri-chemical industry reports! The scale of plagiarism was extremely alarming; more than 50 percent of the chapters were plagiarized, including whole pages of text.

The World Health Organization has classified glyphosate as a probable human carcinogen. French President Emmanuel Macron has pledged to outlaw it completely in France by 2021.

artificially colored food & candy causes cancer

artificially colored food & candy causes cancer

Food dyes are one of the most widely used and dangerous additives, yet are openly marketed and sold in the US despite proof that they are carcinogens.


The three most widely used dyes, Red 40, Yellow 5, and Yellow 6, are contaminated with known carcinogens … ☠

Another dye, Red 3, has been acknowledged for years by the Food and Drug Administration to be a carcinogen, yet it is still in the food supply.

In their 58-page report (PDF), “Food Dyes: A Rainbow of Risks,” The Center for Science in the Public Interest (CSPI) revealed that nine of the food dyes currently approved for use in the United States are linked to health issues ranging from cancer and hyperactivity to allergy-like reactions.

The European Union has recently placed regulations on labeling food dyes to inform consumers of the health risks. The United States has no such requirement.  🇺🇸 Per Usual.

I’m not even saying outlaw them entirely. Just make it known on the label, so we can make an informed choice ourselves!
