Hair Dye And Breast Cancer Risk: New research raises a concern about the safety of permanent hair dyes and cancer with straighteners linked to breast cancer, especially among African American black women.
The study OR research was published this Wednesday in the International Journal of Cancer.
Chemicals in hair dye and hair straighteners
Previous research in animals has found links between certain chemicals in hair dye and hair straighteners connected with cancer cells. But findings from other human studies or other human research on the association between hair dyes and cancer have been inconsistent. This large, prospective study provides firmer evidence of a link between hair dye and breast cancer.
Hair dye and breast cancer risk
White women who are using hair dyes or hair Straighteners did not see a significantly increased risk of breast cancer.
Here, reasons are unclear for Hair dyes and Cancer risk: It may be because different products are designed for women of different ethnic and racial backgrounds, or that variations or several products in hair texture alter the amounts of dye that are applied or absorbed through our skin.
Hair dye and cancer myth or danger
The study followed 46,700 American women who were already enrolled in the National Institutes of Health’s(NIH is the largest biomedical research agency in the world) “Sister Study,” which perfectly tracks breast-cancer-free women whose biological sisters were diagnosed with cancer or with breast cancer.
The women, age 35 to 74, perfectly answered lifestyle questions like, what hair products they used, and updated researchers over an average of eight years.
USA women who have a high risk of breast cancer
The researchers found that, compared to those who did not use dyes at all, women who did had a 9% higher risk of getting breast cancer by hair dye — but when researchers looked specifically at African American black women using dye, they were found to have a 45% higher risk of being diagnosed.
Actually, the study perfectly found that women who had used the dyes and chemical straighteners had a greater risk or chance of being diagnosed with breast cancer. This was especially true if those women identified as Black(African American black women).
Hair Dyes And Cancer Risk
This study also implicated hair straighteners also which is used for straightening or hair especially used by black women who have curly hair, finding a 30 percent increase in the risk of breast cancer among women of all races who reported regular use of the best hair products.
Straighteners For Curls Hair – Breast cancer risk
African-American women were much more likely than white women to use hair straighteners because or their curls hair, the researchers noted.
Still… some preliminary research has linked hair dye to blood and bladder cancer(Bladder cancer is where a growth of abnormal tissue, known as a tumor, develops in the bladder lining).
One study found that salon employees or who are going salon regularly had a small increased risk for bladder and other cancers.
Some scientists said the findings were concerning because of how popular and famous hair products are. In the study, more than half said they had used hair dye(not mention branded or not), and nearly three-quarters of black women reported using hair straighteners.
All Hair Products are tested or safe
Most of the hair products put out there on the market today are not adequately tested or even check for that particular benefit or for safety, and they are not tested for endocrine-disrupting chemicals, referring to additives that interfere with hormones in our body.
Here, researchers note that in the United States, breast cancer incidence remains very high for all women(black lady and white lady) and appears to be increasing for non-Hispanic black lady or women, who also are more likely to be diagnosed with more and more aggressive forms of the disease and more likely to die from it.
Hair dye and breast cancer risk by harmful chemical: You are using Hair products that contain more than 5,000 chemicals which are very harmful to your body, according to researchers, including those with mutagenic and endocrine-disrupting properties such as aromatic amines, which can raise breast cancer risk very fast.
Hair Dye And Breast Cancer Risk Example
Much more research is needed, to know for sure how these hair products are risky to use. For example, very long-term clinical trials with a control group and placebo would be more definitive for breast cancer, but this type of study “would be difficult if not impossible to do.”
“Sometimes science can’t give us all real answers that we really want it to give us,” says Dr. Otis Brawley.
Dr. Doris Browne who is a medical oncologist and former president of the National Medical Association(NMA is the collective voice of African-American physicians and the leading force for parity and justice in medicine and the elimination of disparities in best health), suggests that women should start a friendly conversation with their doctor about their risk for breast cancer.
Very important for all women
“I think it is really important for all women who are suffering from this problem, particularly African and American women, not to panic every time a study comes out,” she says. “But it should really raise our valuable questions for our primary care providers.”
For example, Dr. Doris Browne actually suggests doctors and patients conversation or discuss the use of best hair products. It should be like dyes and straighteners along with other aspects of a “social history” like alcohol consumption, smoking or vaping, obesity and living near natural environmental contaminants.
So, Dr. Doris Browne says, the actual key lesson from this study for both doctors and patients is that “when we are aware of a new association (of breast cancer risk) we really need to increase our surveillance very fast” to include this actual potential risk factor in doctor-patient conversations or discussions.
While it is worth being conscious of the risks associated with cosmetics, Alexandra White says it is too soon to swear off hair dye.
Hair dye and breast cancer risk development tracked
The study actually tracked a relatively very small group of women who really developed cancer. And the disease is actually almost never caused by one thing alone. “We actually know that many different factors influence breast cancer risk,” Alexandra White says.
Dr. White suggested that women switch from permanent dyes to semi-permanent dyes, which were not found to be associated with an increase in breast cancer.
There was no increased risk for women who used semi-permanent or temporary dyes or temporary hair Straighteners, the kind that eventually wash out with shampooing.
Hair dye and breast cancer risk, To reduce the risk of cancer, researcher White says women might want to choose these products instead.
