Researchers have found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don’t use these products.

The study, published in the International Journal of Cancer, suggests that this risk increased with more frequent use of these chemical hair products.


“Researchers have been studying the possible link between hair dye and cancer for a long time, but results have been inconsistent,” said study author Alexandra White from National Institute of Environmental Health Sciences (NIEHS) in US.

“In our study, we see a higher risk associated with hair dye use, and the effect is stronger in African American women, particularly those who are frequent users,” White said.

Using data from 46,709 women in the Sister Study, researchers at NIEHS, found that women who regularly used permanent hair dye in the year prior to enrolling in the study were nine per cent more likely than women who didn’t use hair dye to develop breast cancer.

Among African American women, using permanent dyes every five to eight weeks or more was associated with a 60 per cent increased risk of breast cancer as compared with an eight per cent increased risk for white women.

The research team found little to no increase in breast cancer risk for semi-permanent or temporary dye use.

An intriguing finding was the association between the use of chemical hair straighteners and breast cancer.

The researchers found that women who used hair straighteners at least every five to eight weeks were about 30 per cent more likely to develop breast cancer.

While the association between straightener use and breast cancer was similar in African American and white women, straightener use was much more common among African American women, the study said.

The researchers cautioned that although there is some prior evidence to support the association with chemical straighteners, these results need to be replicated in other studies.

When asked if women should stop dyeing or straightening their hair, study co-author Dale Sandler, “We are exposed to many things that could potentially contribute to breast cancer, and it is unlikely that any single factor explains a woman’s risk.

“While it is too early to make a firm recommendation, avoiding these chemicals might be one more thing women can do to reduce their risk of breast cancer,” Sandler said.(IANS)

Canadian researchers have discovered an overlooked gene that plays a major role in the development of antibodies

Canadian researchers have discovered an overlooked gene that plays a major role in the development of antibodies, which help the immune system recognize and fight viruses including SARS-CoV-2, bacteria and other causes of infectious disease. The gene -- FAM72A -- facilitates production of high-quality antibodies by enabling the effect of an enzyme called AID (for Activation-Induced Deaminase), the researchers showed.

Immunologists have known for two decades that AID is essential to produce antibodies capable of clearing infections, but the full mechanism of its effect has remained unknown. "Our findings answer the long-standing question of how AID does its work," said Alberto Martin, a professor of immunology at the University of Toronto's Temerty Faculty of Medicine. "FAM72A helps AID to promote mutations in antibody genes that are essential for the development of effective antibodies," he added.

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.

This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.
