  • Long-term night shift work among women increased the risk of cancer by 19%.
  • A meta-analysis using using international data from 61 articles comprising 114,628 cancer cases and 3,909,152 participants.
  • These studies found an association between long-term night shift work and risk of 11 types of cancer.

Women who work overnight have a comparatively high risk of developing cancer than women who do not, say researchers. An analysis of international data has confirmed an association between night-shifts and cancer.

“Our study indicates that night shift work serves as a risk factor for common cancers in women,” said Xuelei Ma, co-author of the study from West China Medical Center of Sichuan University in Chengdu, China.

  • Long-term night shift work among women increased the risk of cancer by 19 percent.
  • Nurses (working in night shifts) had the highest risk of breast cancer, of all the occupations analysed.
  • The population of women working on night shifts have an increase risk of skin (41%), breast (32%) and gastrointestinal cancer (18%).
  • Among female nurses alone, those who worked the night shift had an increased risk of breast (58%), gastrointestinal (35%) and lung cancer (28%).

Methodology

  • A meta-analysis using data from 61 articles comprising 114,628 cancer cases and 3,909,152 participants from North Amercia, Europe, Australia and Asia.
  • The articles consisted of 26 cohort studies, 24 case-control studies and 11 nested case-control studies.
  • These studies found an association between long-term night shift work and risk of 11 types of cancer.

“Nurses that worked the night shift were of a medical background and may have been more likely to undergo screening examinations,” the researcher suggested.

“Long-term night shift workers should have regular physical examinations and cancer screenings,” Ma noted.

High carbohydrate intake may increase cancer recurrence risk

Five-year survival rates among these patients continue to be low, in part because these cancers are often detected in the later stages

Consuming high amounts of carbohydrates and sugar prior to treatment for head and neck cancer may increase the patients’ risks of cancer recurrence and mortality, a new study reports.

Patients who consumed the most total carbohydrates and sugars — in the form of sucrose, fructose, lactose and maltose — in the year preceding the cancer treatment were at greater risk of mortality from any cause during the follow-up period. Out of the 400 cancer patients in the study, published in the International Journal of Cancer, more than 17 per cent experienced recurrence of their cancer, and 42 patients died from it.

Associations among carbohydrate intake and patient outcomes differed by cancer type and stage, said lead author Anna E. Arthur, professor at the University of Illinois at Urbana-Champaign.

However, eating moderate amounts of fats and starchy foods such as whole grains, potatoes and legumes after treatment could have protective benefits, reducing the patients’ risks of disease recurrence and death, he added.

“Our results, along with the findings of other studies, suggest that diet composition can affect cancer outcomes,” said co-author Amy M. Goss, professor at the University of Alabama.

Higher mortality rates were found among people with oral cavity cancer who consumed the greatest amounts of total carbohydrates, total sugars and simple carbohydrates, but the researchers found no such associations among people who had oropharyngeal cancers.

Chronic diseases are not yet included in cancer prevention schemes.
Cancer can be caused due to too much sugar.

“Although in this study we found that higher total carbohydrate and total sugar were associated with higher mortality in head and neck cancer patients, because of the study design we can’t say that there’s a definitive cause-effect relationship,” Arthur said.

Five-year survival rates among these patients continue to be low, in part because these cancers are often detected in the later stages, putting patients at high risk of recurrence, the researchers said. IANS

  1. I was about to take Cruise Ship Management in school last year. But unfortunately, when I received the result in hepatitis b test, it was positive. I don’t know where I got this. I’ve never experienced having sex with any man or boyfriend. I was so disappointed at that time. But then again, it is never the end of the world. I repeated the test in a well-known hospital. But, it came back positive again. Early this year i purchase Hepatitis B herbal remedy online from BEST HEALTH HERBAL CENTRE. They told me i will be negative after 4-5 weeks of usage of their Hepatitis B herbal remedy, which i believed and have faith. After 5 weeks of usage, I did another test my HBsAg came negative in routine checkup, so I have done all investigations for hepatitis B. My test reports are HBsAg negative 0.04 on 22/02/2018. I will never stop telling the world about BEST HEALTH HERBAL CENTRE good work in human life .
