New research funded by the British charity group Breast Cancer Now has shown little or no connection between shift work and bad cancer development. The results contradict a previous report of the International Agency for Research on Cancer. ( pixabay )
Women working during the night shift are not likely to increase their risk of bad cancer, contrary to what the researchers initially thought.
Breast Cancer Now, a UK-based charity, has funded new research to determine the impact of shift work on women's health. The researchers found that working during the evening did not increase the risk of bad cancer in women.
The findings are inconsistent with those presented in a 2007 report by the International Agency for Research on Cancer, which suggested that disrupting the sleep-wake cycle of the body due to shift work was probably carcinogenic.
"A possible link between electrical light exposure at night and an increased risk of bad cancer had been proposed for the first time over 30 years ago, but research has not shown up until recently. here was not conclusive, "said Michael Jones, a scientist at the Cancer Institute, co-author of the Breast Cancer Now study.
"In our new study, we found no overall relationship between women who performed night work in the last 10 years and their risk of bad cancer, regardless of their type of work involving teams of women. night and their age. " such work. "
Risk of bad cancer in women
IARC's 2007 report described a potential link between shift work and an increased risk of bad cancer among women. His findings then served as a basis for the Danish government to pay allowances to dozens of women who claimed to have developed the disease as a result of their night work.
In the latest study, Breast Cancer researchers now developed the findings of the 2016 meta-badysis, which found a weak or no badociation between shiftwork and illness. This earlier research was questioned because of the higher average age of participants and the limited details provided on the nature of shift work for women.
To solve these problems, Jones and his colleagues recruited participants averaging 45 years old. About 17.5% of these people reported being night workers, whose usual work hours were between 10 pm. and at 7 o'clock in the last 10 years. Participant team data were also tracked six years later.
No badociation between shift work and bad cancer risk
Of the 102,869 women who participated in the study, 2,059 of them were subsequently diagnosed with invasive bad cancer. The researchers examined the confounding risk factors badociated with the occurrence of cancer, but they found no overall connection with night work.
The team also did not find a significant difference in bad cancer risk based on the type of night work participants did, the age they started working, or the fact that they started working. before or after their first pregnancy.
The researchers found that the only statistically significant trend observed was that of the average number of night hours worked each week by the participants. However, Jones and his team stated that this result was not supported by previous evidence or even by any proposed biological explanation.
Breast Cancer Now's CEO, Delyth Morgan, said they hoped the results of their study would help many women working at night to ensure that their work habits do not increase their risk of contracting the disease.
Although researchers may have found no correlation between shift work and bad cancer risk, they cautioned that such work habits may still have adverse health effects.
The results of the study sponsored by Breast Cancer Now are presented in the British Journal of Cancer.
