Ladies, avoid sitting for long hours to prevent cancer

The study finds that women who spend long hours sitting during leisure time are at 10% higher risk of cancer, including ovarian and breast. The study however does not find the same for men.

Women who sit for long durations are at a higher risk of cancer, including breast and ovarian than those who don't, according to a new study by American Cancer Society.

Sitting during leisure time can increase cancer risk by 10% higher risk of cancer, says the study led by Alpa Patel.

"The higher risk was present even after taking into account body mass index (BMI), physical activity, and other factors," says the study led by Alpa Patel from American Cancer Society.

The study published in the journal Cancer Epidemiology, Biomarkers, and Prevention, however, finds no association between sitting time and cancer risk in men.

"Longer leisure-time spent sitting was associated with a higher risk of total cancer risk in women, and specifically with multiple myeloma, breast and ovarian cancers, but sitting time was not associated with cancer risk in men," says the study.

Only few studies examine the link between sitting time and cancer risks, although extensive research links physical activity to cancer prevention.

Technological advancements and lifestyle changes have increased the time spent sitting over the past few decades. Computers and video games, and changes in transportation have further added to the cause.

The study compares leisure time sitting to cancer risk among more than 146,000 men and women (69,260 men and 77,462 women) who were cancer-free. Between 1992 and 2009, 18,555 men and 12,236 women were diagnosed with cancer.

While researchers find that longer leisure-time spent sitting is associated with a 10% higher risk of cancer in women after adjustment for physical activity, BMI and other factors, the association is not apparent in men.

"Further research is warranted to better understand the differences in associations between men and women," the study says.
