Sitting too Much Linked to Breast Cancer

Spending too much time sitting down doesn’t only increase the risk for obesity. New research out of Sweden shows sitting for hours on end at work and during off hours may hike a women's risk of breast and endometrial cancer.

The findings, presented this week at the meeting of the American Association for Cancer Research in Philadelphia, are based on an analysis of medical records for more than 29,000 Swedish women ages 25 to 64 who did not have cancer at the study's start. The women were followed for about 25 years, Fox News reports.

The women were divided into three groups: those who had a sedentary job and did not engage in recreational sports, those who had a sedentary job but did participate in sports (such as running and handball), and those who had a physically active jobs that required more standing up (such as being a teacher) and were active in sports.

The least active women were 2.4 times more likely to be diagnosed with endometrial cancer (a cancer of the uterus lining) and breast cancer before menopause, compared with those who were active at their jobs and in their leisure time.

There was no link between inactivity and an increased risk of breast cancer after menopause.

People who work in offices and sedentary jobs should break up their siting time by going for walks, getting up for coffee, walking to work, or making time for brief bursts of exercise, said researcher Anna Johnsson, a physical therapist at Lund University in Sweden.

The findings echo previous studies that have found a link between inactivity and the risk of various cancers. Some have suggested taking short breaks throughout the day to move around reduces levels of molecules in the blood that are linked with cancer risk.

A 2011 study estimated that being inactive was linked to as many as 49,000 of the 249,000 cases of breast cancer diagnosed each year in the United States.
