Study Reveals Hair Dyes And Straighteners Increase The Risk Of Breast Cancer

What Does The Study Say

Publishedin the International Journal of Cancer, the study explored the possible links between cancer and chemical hair products. It looked at data from 46,709 women in the Sister Study, a long-term investigation focusing on women with a family history of breast cancer. The study aimed to explore how various hair products might influence breast cancer risk, providing crucial insights into the potential dangers lurking in everyday beauty routines.

According to the study, hair products contain Endocrine-Disrupting Compounds (EDC) and carcinogens potentially relevant to breast cancer among women. EDC is a substance that interferes with the body's hormonal system and can mimic or block hormones, leading to health issues such as reproductive problems and certain cancers. Whereas, carcinogens are agents that can cause cancer by damaging DNA or disrupting normal cell processes in the body. 

It was found that women who used permanent hair dye had a 9% increased risk of developing breast cancer compared to non-users. Among African American women, this risk was even more pronounced, as they faced a staggering 60% higher risk compared to their white counterparts, who experienced an 8% increase at similar usage rates.

The use of chemical hair straighteners also posed significant risks. According to the study, women who used these products at least every five to eight weeks had about a 30% higher risk of developing breast cancer. This increased risk was seen in women of all races. However, African American women were more likely to use these straighteners regularly.

What Are the Risk Factors For Breast Cancer?

Breast cancer risk factors can be categorized into those that cannot be changed and those that can be influenced by lifestyle choices. Understanding these factors is crucial for prevention and early detection.

• The risk increases with age, particularly after 50.

• Having a close relative, mother, sister, or daughter with breast cancer significantly raises your risk. Genetic mutations also increase susceptibility.

• Women who have previously had breast cancer or certain noncancerous breast conditions are at a higher risk.

• Early menstruation, before age 12, or late menopause after age 55, having children later in life, or never having children can increase risk.

• Women with dense breasts have a higher risk and may find it harder to detect tumours on mammograms. 

• Being overweight, especially after menopause, increases risk.

What Are The Symptoms Of Breast Cancer?

Breast cancer can present various symptoms, and being aware of these signs is crucial for early detection. Below are a few common symptoms to look out for. 

• A new lump in the breast or underarm is often the first noticeable symptom. It can feel hard or soft and may not always be painful.

• Noticeable changes in the size, shape, or appearance of one or both breasts can be a warning sign.

• Changes in the nipple's appearance, such as turning inward, inverted nipple or developing a rash, can indicate a problem.

• Any fluid leaking from the nipple that is not related to breastfeeding or pregnancy, especially if it contains blood, should be checked by a doctor.

Conclusion

The study on hair dyes, chemical straighteners, and an increased risk of breast cancer highlights the need for ongoing research into the safety of cosmetic products. As the beauty industry evolves, consumers must make informed choices about the products they use. Understanding ingredients and being aware of breast cancer symptoms can empower women to prioritize their health alongside their beauty routines.
