A large study published on Monday suggests that people who use hair-straightening products frequently are more likely to develop uterus cancer.

According to the study leader, the risk of developing uterus cancer goes up to 4% for frequent users.

Profs Uğur Şahin and and Özlem Türeci of BioNTech are interviewed by Laura Kuenssberg.

The BioNTech founders say that vaccines can be used to treat cancer in the near future.

It is important to understand this information. She said that uterine cancer is rare.

Black women are more likely to be diagnosed with uterine cancer than other women, according to the CDC.

For an average of nearly 11 years, researchers tracked 33,970 racially diverse women. 358 women were diagnosed with uterus cancer.

The odds of developing uterine cancer were more than two and a half times higher for women who had used straightening products more than four times in the previous year.

It might have been due to chance that less frequent use of straighteners in the past year was associated with an elevated risk of uterine cancer.

Studies show that hair straighteners contain chemicals that disrupt hormones. Higher risks of breast and ovarian cancer have been linked to the products.

White and colleagues wrote about their findings in the Journal of the National Cancer Institute. There is more research that needs to be done to identify the chemicals that are driving this association.

Race did not affect the link between straightener use and cancer.

Che-Jung Chang said in a statement that the findings may be more relevant for black women because they use hair products more frequently.
