    SCIENTISTS have raised the alarm over factors fuelling new cases of cancer globally, saying women who work night shift regularly might be at greater risk for a number of cancers. This is the findings of a study published in the journal ‘Cancer Epidemiology, Biomarkers and Prevention’.

    The researchers found that working during the wee hours over the long term was associated with a 19 per cent greater risk of cancer among women. Consequent upon these developments, lead author of the study, Xuelei a, who is an oncologist in the State Key Laboratory of Biotherapy and Cancer Center at West China Medical Center of Sichuan University, urged workers who do night shift on long term to have regular physical examinations and cancer screenings as a strategy to preventing cancers and ensuring early detection.

    “Our study indicates that night-shift work serves as a risk factor for common cancers in women,” he said. Cancer is one of the leading causes of morbidity and mortality worldwide, with approximately 14 million new cases in 2012. The number of new cases is projected to rise by about 70 per cent over the next two decades.
    Similarly, cancer is the second leading cause of death worldwide, and was responsible for 8.8 million deaths in 2015. Globally, nearly one in six deaths is due to cancer. Approximately 70 per cent of deaths from cancer occurs in low- and middle-income countries. According to WHO estimates, cancer is one of the highest killer diseases in Nigeria as 100,000 cancer deaths are recorded annually while 250,000 new cases emerge yearly.

    On the new study, ‘healthday’reported that looking at specific types of cancer, Ma and his colleagues found that the risk of skin cancer jumped 41 per cent, the risk of breast cancer increased 32 per cent and the odds of developing gastrointestinal cancer was 18 per cent higher among women, who were long-term night-shift workers.

    However, the study did not prove that night-shift work caused the risk of these cancers to rise, the report stated. The researchers conducted a review of 61 studies involving almost four million people from North America, Europe, Australia and Asia, to look for an association between long-term nightshift work and the risk of 11 types of cancer.
